Mattress Warranty Prorated vs Non-Prorated: The Math That Separates Real Coverage From Marketing Language

A prorated mattress warranty depreciates the value of your mattress on a published schedule. A non-prorated warranty pays full replacement or repair regardless of how many years have passed. The difference is the single most important variable in mattress warranty coverage, and it explains why two beds marketed as having "lifetime warranties" can produce wildly different payouts on the same defect. Saatva, Tempur-Pedic, and Amerisleep are the three mass-market brands with the strongest non-prorated language. Most of the rest, including most "lifetime" warranties from Nectar, DreamCloud, Bear, and Brooklyn Bedding, prorate after year ten or fifteen.

TL;DR Direct Answer

• Non-prorated: Full replacement value across the warranty term. Saatva (lifetime, $99 repair-for-life after year 2), Tempur-Pedic (10 years full), Amerisleep (years 1-10 full).
• Prorated: Customer pays a depreciation share. Typical schedule: 50 percent at year 5-7, 75 percent at year 8-10. Nectar, DreamCloud, Brooklyn Bedding, Bear (years 11+), most Mattress Firm SKUs after year 5.
• The marketing trick: "Lifetime warranty" without "non-prorated" almost always means full coverage for 10 years then prorated thereafter. Read the fine print.
• 10-year prorated math on a $1,500 Queen: 50 percent at year 5 = customer pays $750 toward replacement. 75 percent at year 8 = customer pays $1,125. 100 percent at year 10 = customer pays full retail.
• Saatva's $99 repair fee starting year 3 is the most generous payout structure on the market: same fee in year 3 as in year 30.
• The other variable that matters: sagging threshold. Tempur and Amerisleep at 0.75" beat Saatva at 1.0-1.5" and Mattress Firm at 1.5".

What Prorated and Non-Prorated Actually Mean

A warranty defines who pays for what when a covered defect occurs. The legal structure is contractual: the manufacturer agrees to remedy specific defects (sagging beyond a threshold, foam splitting, coil failure) under specific conditions (clean mattress, proper foundation, original purchaser). The single question that determines the payout is whether the remedy includes full replacement or a depreciation share.

Non-prorated means the manufacturer pays the full cost of replacement or repair, no matter how many years have passed within the warranty term. A 10-year non-prorated warranty pays full replacement in year 1, year 5, and year 10. The customer pays nothing toward the replacement product itself, though some brands charge a flat handling or shipping fee (Saatva's $99 repair fee, Tempur's $175 shipping fee).

Prorated means the manufacturer pays only a percentage of replacement cost, with the percentage decreasing over time according to a published schedule. The customer pays the remaining share. A typical 10-year prorated schedule pays 100 percent in years 1-2, then drops by 5 to 10 percent per year, until the customer is paying nearly the full retail in year 10. A "lifetime prorated" warranty extends the depreciation schedule indefinitely, often with a floor (50 percent reimbursement) that holds for the remaining life of the product.

The two structures are not interchangeable. A 10-year non-prorated warranty pays out roughly four times the dollar amount of a 10-year prorated warranty on a year-eight claim. Brands rarely advertise the proration schedule prominently. The number that matters is buried in the warranty PDF, not on the marketing page.

The Math: A $1,500 Queen Across 12 Brands

Here is the actual financial outcome of a covered sagging defect on a $1,500 Queen mattress, filed at different points in the warranty term, across the major brands. The defect is a 1.5-inch indentation, which exceeds every brand's threshold. The customer's out-of-pocket cost is the variable.

Brand	Year 2 Claim	Year 5 Claim	Year 8 Claim	Year 11 Claim	Year 20 Claim
Saatva Classic ($1,500 Queen)	$0	$99	$99	$99	$99
Tempur-Pedic Cloud ($2,000 Queen)	$175 ship	$175 ship	$175 ship	Out of warranty	Out of warranty
Amerisleep AS3 ($1,500 Queen)	$0	$0	$0	~$750 (50% prorated)	Out of warranty
Nectar ($1,200 Queen)	$0	~$300-600 (varies)	~$600-900	~$600 (50%)	~$600 (50%)
DreamCloud Premier ($1,400 Queen)	$0	$0	$0	~$700 (50%)	~$700 (50%)
Casper Original ($1,200 Queen)	$0	~$600 (50% after yr 5)	~$800	Out of warranty	Out of warranty
Sealy Posturepedic ($1,400 Queen)	$0	~$350 (25%)	~$700 (50%)	Out of warranty	Out of warranty
Purple Mattress ($1,400 Queen)	$0	$0	$0	Out of warranty	Out of warranty
Helix Midnight Luxe ($1,800 Queen)	$0	$0	$0	~$900 (50% after yr 10)	Out of warranty
Bear Elite Hybrid ($2,400 Queen)	$0	$0	$0	~$600-1,200 (50-75%)	~$600-1,200
Brooklyn Bedding Aurora ($1,900 Queen)	$0	$0	$0	~$950 (50%)	~$950
Zinus Green Tea ($600 Queen)	~$60 (10%)	~$300 (50%)	~$480 (80%)	Out of warranty	Out of warranty

The pattern is clear. Saatva is the only brand where the year-20 claim still pays out, and pays out at the same $99 cost as the year-3 claim. Tempur-Pedic and Amerisleep offer strong non-prorated coverage for the first decade. After year 10, only Saatva and the Bear/Brooklyn Bedding "limited lifetime" tier still cover the mattress at all, and only Saatva does so on a flat-fee basis.

Typical Proration Schedules

Proration schedules vary by brand but follow predictable patterns. Here are the typical structures we documented in May 2026.

The 10-year linear schedule: Customer pays 10 percent of replacement cost per year owned starting in year 1 (or year 2 in some cases). At year 5, customer pays 50 percent. At year 10, customer pays 100 percent (effectively no coverage). Used by some legacy mid-tier brands and by Zinus.

The 5-year cliff schedule: Full non-prorated coverage for years 1-5, then prorated 50 percent for years 6-10. Customer pays 50 percent at year 6, 75 percent at year 9. Used by Casper Original.

The 10-year cliff schedule: Full non-prorated coverage for years 1-10, then prorated 50 percent for the remaining lifetime. Customer pays 50 percent at year 11 onward. Used by Helix (in lifetime limited models), Bear (50 to 75 percent depending on damage assessment), Brooklyn Bedding Aurora, Nectar, DreamCloud.

The 10-year ramp-down: Years 1-2 full coverage, years 3-5 customer pays 25 percent, years 6-8 customer pays 50 percent, years 9-10 customer pays 75 percent. Used by Sealy Posturepedic and some legacy Mattress Firm SKUs.

The flat-fee structure: Customer pays a flat handling or repair fee regardless of years owned. Saatva's $99 repair-for-life starting year 3. This is functionally a non-prorated lifetime warranty with a fixed transaction cost.

Brand Mapping: Who Is Truly Non-Prorated

Strip out the marketing language and the universe of truly non-prorated mattress warranties is small.

Lifetime non-prorated (Tier 1): Saatva is the cleanest example. The warranty pays full replacement for years 1-2 and a flat $99 repair fee for every subsequent year. The repair option remains available indefinitely. There is no proration ever. WinkBeds Original offers 10 years of full non-prorated coverage, then transitions to a prorated repair structure for the remaining lifetime. Bear Elite Hybrid offers 10 years of full coverage, then 50 to 75 percent depending on the defect type for years 11+, which sits at the edge of non-prorated.

10-year full non-prorated (Tier 2): Tempur-Pedic is the standout. The Cloud, Adapt, and ProAdapt lines all carry 10 years of full replacement, no proration. The $175 return shipping fee is a flat handling cost, not a depreciation share. Beautyrest offers 10-year non-prorated on most of its lineup. Leesa Original is 10-year non-prorated. Helix base mattresses (not Luxe) are 10-year non-prorated.

20-year with 10 years non-prorated (Tier 2.5): Amerisleep is the only brand at this tier in mass-market DTC. Years 1-10 are fully covered. Years 11-20 are prorated, typically at 50 percent. This sits between Saatva's lifetime structure and the 10-year-only tier.

"Lifetime" prorated (Tier 3): Nectar, DreamCloud, Brooklyn Bedding Aurora, Bear Original. These warranties extend coverage past year 10 but only with 50 percent customer contribution. The marketing language obscures this, but the warranty PDF makes it explicit.

10-year prorated (Tier 4): Casper Original, Sealy Posturepedic, Stearns & Foster, Serta, Sleepy's (Mattress Firm house). Coverage drops sharply after year 5, and most claims filed in year 7+ result in significant customer co-pay. Zinus and Linenspa sit at the bottom of this tier with proration starting in year 1 or 2.

Saatva: Why $99 Repair-for-Life Wins the Math

Saatva's "Friends for Life" warranty is the most generous payout structure in the market. The mechanics: full replacement at no charge during years 1-2 for any covered defect. Starting year 3, Saatva offers a repair-and-recover service for a flat $99 fee, which includes pickup of the defective mattress, repair or re-cover of the defect, and return delivery via the white-glove crew. The $99 fee never changes. The repair option remains available for the entire lifetime of the original purchaser.

For warranty claims involving structural failure that cannot be repaired (severe coil failure, foam decomposition), Saatva offers a "Fairness Replacement Option" allowing the customer to receive a prorated replacement once during the lifetime of the mattress, with the proration based on years of ownership. This is the one carve-out where Saatva does apply proration, and it is the customer's choice to invoke it rather than the brand's default response. Most claims are handled through the $99 repair channel.

The math on a year-15 sagging claim on a $1,500 Queen Saatva: customer pays $99, Saatva picks up the mattress, repairs the defect, returns the mattress, and the warranty resets for any subsequent issue. Same $1,500 Queen at Nectar in year 15: customer pays $750 (50 percent of original retail) toward a replacement, plus shipping logistics. At DreamCloud: same $750 plus pickup coordination. At Casper: warranty has expired entirely. Saatva pays out $99 across every year of the warranty term. Nectar and DreamCloud pay out $750. The Saatva structure is $651 less expensive on a single claim filed in year 11 or later.

Tempur-Pedic: 10-Year Non-Prorated, Strictest Threshold

Tempur-Pedic's 10-year warranty is the strongest 10-year coverage in the industry. Full replacement on any covered defect, no proration ever, no co-pay on the replacement product. The $175 return shipping fee is the only out-of-pocket cost. The trade-off is the sagging threshold: Tempur requires a documented indentation of 0.75 inches measured with a quarter and straight edge. This is the strictest threshold among the major brands (Saatva is 1.0 to 1.5 inches depending on model, Sealy and Beautyrest are 1.5 inches). The strict threshold benefits Tempur in two ways: low-density foam claims rarely meet it, and the 7 lb/ft³ density of Tempur memory foam genuinely resists sag for the full warranty term.

Tempur's 10-year ceiling is also a real ceiling. After year 10, the mattress is uncovered. A defect in year 11 is the customer's problem entirely. For buyers who want certainty for one decade and replacement intent at year 10, this matches the typical mattress lifespan (7 to 10 years per Sleep Like the Dead's longitudinal owner surveys). For buyers who plan to keep the mattress for 15 to 20 years, Saatva's lifetime structure provides material additional value.

Amerisleep: 20 Years With a Decade of Non-Prorated

Amerisleep's 20-year warranty is the longest documented warranty term in mass-market DTC outside Saatva's lifetime structure. The terms: full non-prorated replacement for years 1-10. Years 11-20 are prorated at typically 50 percent, meaning the customer pays half of the original retail toward a replacement product. The sagging threshold is 0.75 inches, matching Tempur and tighter than Saatva. The Bio-Pur plant-based foam at 4 lb/ft³ density is genuinely durable, and Amerisleep's HIVE 5-zone support layer engineering means hip and shoulder zones see less repeated compression than uniform-density alternatives.

Amerisleep's structure is the strongest value play for buyers who want premium DTC quality at a sub-$1,500 Queen price with longer-than-Tempur coverage. The AS3 Queen at $1,249 on sale, paired with 10 years of full non-prorated coverage and 10 more years at half-price replacement, is a competitive position against Saatva's $1,500 to $1,800 Queen with lifetime $99 repair. Saatva still wins the absolute math on year 11+ claims, but Amerisleep's initial price premium is roughly $250 to $550 lower.

The "Lifetime" Marketing Trap

The phrase "lifetime warranty" without the qualifier "non-prorated" is the most common marketing trap in the mattress industry. Nectar markets a "Forever Warranty." DreamCloud markets a "Lifetime Warranty." Both terms imply unlimited coverage. Both warranties are functionally 10-year non-prorated warranties with a depreciated payout structure for the remaining lifetime.

The Nectar Forever Warranty PDF, available on the Nectar website, specifies that after year 10 the customer can request a repair or replacement but pays 50 percent of the original retail value plus a $50 transportation cost. A 10-year-old Nectar Queen ($1,200 original retail) producing a 1.5-inch sag in year 12: customer pays approximately $650 ($600 plus $50 shipping) toward a replacement. The same defect on a 12-year-old Saatva: customer pays $99 flat.

DreamCloud's structure is essentially identical. The "lifetime" claim is technically true (coverage extends beyond year 10) but functionally similar to a 10-year warranty with a 50 percent depreciation floor.

When evaluating a "lifetime warranty," look for two phrases in the warranty PDF: "non-prorated" (meaning full coverage regardless of years) and "flat fee" or "repair fee" (meaning a fixed handling cost without depreciation). If neither phrase appears in the lifetime tier, the warranty is prorated.

Sagging Threshold: The Second Variable That Decides Claims

The proration question is half the equation. The other half is whether your claim qualifies in the first place, which is governed by the sagging threshold. The threshold is the minimum measurable indentation depth that the brand recognizes as a covered defect. Lower threshold equals more claims approved.

Brand	Sagging Threshold	Foam Density (Comfort Layer)	Implication
Tempur-Pedic	0.75"	7 lb/ft³	Strictest threshold; densest foam can support it
Amerisleep AS3	0.75"	4 lb/ft³	Strict threshold with mid-density foam
Saatva Loom & Leaf	1.0"	5 lb/ft³	Moderate threshold; high-density foam easily meets it
Purple	1.0"	Hyper-Elastic Polymer grid	Grid structure rarely sags traditionally
Helix	1.0"	2.5-3 lb/ft³	Moderate threshold; lower-density foam
Saatva Classic	1.5"	Coil-on-coil	Coil construction; threshold less critical
Sealy, Beautyrest, Serta	1.5"	1.5-2 lb/ft³	Loose threshold protects low-density foam
Nectar, Zinus, IKEA	1.5"	1.5-3 lb/ft³	Loose threshold; foam sags just below threshold

The pattern is not coincidence. Brands selling at 4 lb/ft³ or higher density (Tempur, Amerisleep, Saatva Loom & Leaf) can afford strict thresholds because the foam genuinely does not sag fast. Brands at 1.5 to 2 lb/ft³ set loose thresholds (1.5 inches) because their foam sags faster and a strict threshold would trigger too many claims. The "Sagging Threshold Trap" of low-density foam paired with a 1.5-inch threshold is the single biggest reason BBB warranty denial complaints concentrate at Mattress Firm SKUs and budget Amazon brands.

How to File a Claim That Actually Gets Paid

Whatever brand you own, the mechanics of a successful claim follow a predictable pattern. Documentation matters more than the underlying defect.

1. Photograph the defect with a straight edge and a quarter. Lay a straight edge (a yardstick or carpenter's level) across the indentation. Place a US quarter in the deepest part. Photograph from a perpendicular angle. Save three photos: top-down, side angle, and close-up.
2. Photograph the law tag and the foundation. The law tag confirms the warranty applies. The foundation confirms you have not voided the warranty through unsupported center or wide slats.
3. Pull the original receipt. Most brands require proof of purchase. Saatva and Tempur store this in the customer account; Mattress Firm requires the paper receipt.
4. Call customer service, not the website chat. Phone agents have more discretion than chat bots. Frame the call as a question, not a demand. Ask: "I have a defect that meets the sagging threshold. What is the process to file a claim?"
5. Document everything in writing. Email the brand after the call summarizing the conversation, the claim number, the photos uploaded, and the expected timeline.
6. Escalate if needed. If the claim is denied unfairly, file a BBB complaint, submit a state Attorney General consumer complaint, and consider small claims court for amounts under $5,000 to $15,000 (varies by state). Magnuson-Moss Warranty Act protections apply.

Frequently Asked Questions

What does prorated mean on a mattress warranty?

Prorated means the warranty depreciates the replacement value of the mattress over time. The customer pays a depreciation share that increases with years owned. A typical 10-year prorated schedule has the customer paying 50 percent at year 5, 75 percent at year 8, and 100 percent at year 10. Non-prorated warranties pay full replacement value across the warranty term without any customer co-pay on the replacement product.

Is Saatva's warranty really non-prorated for life?

Yes. Saatva's "Friends for Life" warranty pays full replacement at no charge for years 1-2 and a flat $99 repair-and-re-cover service for every year thereafter. The $99 fee never changes. There is no depreciation, no time ceiling on the repair option, and no co-pay on the replacement product. The one carve-out is the optional "Fairness Replacement," which the customer can invoke once for a prorated replacement; most claims go through the $99 repair channel and bypass proration entirely.

Is Tempur-Pedic's 10-year warranty non-prorated?

Yes. Tempur-Pedic's 10-year limited warranty is fully non-prorated for the entire 10-year term. The customer pays the $175 return shipping fee on covered claims. The replacement product is free. After year 10, the warranty expires entirely; there is no extended coverage.

Does Amerisleep have a non-prorated warranty?

Amerisleep's 20-year warranty is non-prorated for years 1-10 and prorated for years 11-20. During the first decade, covered defects are repaired or replaced at no charge. After year 10, the customer pays approximately 50 percent of the original retail toward a replacement. The sagging threshold of 0.75 inches matches Tempur-Pedic and is stricter than Saatva.

Why does Nectar's "Forever Warranty" pay less than Saatva's?

Nectar's Forever Warranty is non-prorated for the first 10 years and prorated 50 percent for the remaining lifetime. A year-11 Nectar claim pays out 50 percent of the original retail, with the customer paying the other 50 percent plus a transportation fee. Saatva's lifetime warranty has no proration ever, with a flat $99 fee covering the entire repair process. On a $1,500 Queen, a year-11 Nectar claim costs the customer approximately $750. The same Saatva claim costs $99.

What sagging depth qualifies for a warranty claim?

The threshold varies by brand. Tempur-Pedic and Amerisleep require 0.75 inches. Saatva Loom & Leaf, Purple, and Helix require 1.0 inch. Saatva Classic and most Sealy, Beautyrest, Serta, Nectar, Zinus, and IKEA SKUs require 1.5 inches. The measurement is taken with a straight edge across the indentation and a quarter for scale, photographed from a perpendicular angle.

What voids a mattress warranty?

The most common voids across brands are: stains (any stain, including unrelated stains), improper foundation (no center support for queen+, slats wider than 4 inches), removed law tags, and failure to use the mattress on a supportive base. Sleeping arrangements (rotation schedules, weight limits) are also common void clauses. Almost every BBB complaint about denied warranty claims traces back to one of these conditions.
