by Amerisleep’s mattress warranty lasts 20 years: full replacement for qualifying defects in years 1–10, then prorated coverage. Transport or labor charges may apply. Visible indentations must exceed 1.5 inches.
Amerisleep AS3
9.1/10
- 20-year warranty: full replacement years 1–10; transport or labor charges may apply
- 365-night trial with full refund if not satisfied
- HIVE 5-zone support, CertiPUR-US certified, made in the USA
- Partial plant-based Bio-Pur foam, open-cell for breathability
- Warranty is non-transferable; second-hand buyers have no coverage
- Sagging must exceed 1.5 inches on unloaded mattress to qualify
The AS3 is the best-seller in Amerisleep's lineup for good reason: medium feel, HIVE zoned support, and the same 20-year warranty that covers every mattress they make. Years 1–10 provide full replacement for qualifying defects; transport or labor charges may apply. That is the strongest practical protection in this price range.
What the Amerisleep warranty covers
Amerisleep's 20-year warranty addresses three categories of defect. All three must arise from defects in materials or workmanship, not from normal use or physical damage.
| Defect type | Covered? | Details |
|---|---|---|
| Sagging greater than 1.5 inches | Yes | Measured without any weight on the mattress. Visible indentation must exceed 1.5 inches depth. |
| Manufacturing defects in materials | Yes | Defective foam, coil, or fabric arising from production, not from use or damage. |
| Cover or foam layer separation | Yes | Cover detaching or foam layers separating at seams due to workmanship failure. |
Years 1–10: full coverage
During the first ten years, Amerisleep covers 100% of the replacement cost. If the mattress develops a qualifying defect (sagging over 1.5 inches, a manufacturing flaw, or cover/foam separation), Amerisleep provides full replacement. Transport or labor charges may apply; confirm the claim logistics before proceeding.
Years 11–20: prorated coverage
From year 11 onward, Amerisleep's warranty terms set the replacement price at 50% of the original purchase price, plus shipping, cover and labor costs. Get the claim cost in writing before proceeding.
The 1.5-inch threshold is measured with nothing on the mattress. A body impression that looks like 1.5 inches under a sleeper may measure under 1 inch on an unloaded surface. Always measure the indentation with the mattress empty and on a flat, supported foundation before documenting a claim.
What is NOT covered
Claiming for any of the following will result in a denial:
| Exclusion | Covered? | Why not |
|---|---|---|
| Body impressions under 1.5 inches | No | Considered normal wear from regular use |
| Damage from removing the cover | No | The cover is not designed to be removed; damage voids coverage |
| Use on an inadequate or broken foundation | No | Foundation requirements must be met; see the section below |
| Stains, burns, cuts, or physical damage | No | User-caused damage is not a manufacturing defect |
| Normal softening of comfort layers | No | Foam naturally conforms to the body over time; this is expected |
| Second-hand purchases | No | Warranty is non-transferable; original buyer only |
The warranty is separate from Amerisleep's 365-night return trial. If you are within the trial period and the mattress is not right, a return or exchange is a separate process. The warranty covers qualifying defects; the trial addresses whether you want to keep the mattress.
How to file an Amerisleep warranty claim
Amerisleep processes warranty claims through their customer service team. The process is documentation-driven: clear photos of the defect and your original order information are the core of any successful claim.
- Document the defect with photos. Photograph the mattress without any weight on it. For sagging claims, lay a straight edge (yardstick or level) across the surface and photograph the gap beneath it to show depth. Measure the sag depth and photograph that measurement too. For defect or separation claims, photograph the affected area clearly in natural light from multiple angles.
- Contact Amerisleep customer service. Reach out via phone or the contact form on amerisleep.com. State that you are filing a warranty claim and identify the defect type. Have your order number, purchase date, and delivery confirmation ready before you call or submit.
- Submit order info, photos, and a written description. Amerisleep's team will request your purchase documentation and the photos you collected. Write a brief description of when the defect appeared and how it has progressed. The more specific the documentation, the faster the review.
- Wait for Amerisleep's review decision. The review team evaluates your photos and order history against the warranty terms. Follow up by phone if you have not received a decision within 5–7 business days of submission.
- Receive your resolution. Ask for the approved replacement terms and any payment, transport, or labor charges before scheduling the exchange.
- Return the defective mattress if required. Amerisleep may require the original mattress to be returned before or with the replacement. Confirm return logistics with the customer service team before discarding or moving the original mattress.
Amerisleep needs proof of original purchase to validate a warranty claim. Save your order confirmation email and delivery receipt. If you purchased through a third-party retailer, keep that receipt, as retailer purchases may have different warranty fulfillment processes than direct amerisleep.com orders.
Foundation requirements
Using an inadequate foundation voids the warranty. Amerisleep specifies the foundation types that maintain coverage:
| Foundation type | Warranty valid? | Notes |
|---|---|---|
| Slatted foundation (slats 2.75 inches apart or less) | Yes | Slats must be no more than 2.75 inches apart across the full width |
| Solid platform base | Yes | Continuous solid surface with no gaps |
| Box spring in good condition | Yes | No broken or bowing sections |
| Slatted foundation (gaps wider than 2.75 inches) | No | Insufficient support; voids warranty |
| Broken, bent, or bowing frame | No | Cannot provide adequate support; voids warranty |
| Adjustable base (Amerisleep brand) | Yes | Designed for compatibility; verify with customer service for third-party adjustable bases |
The 2.75-inch maximum slat gap is stricter than many standard bed frames provide. Measure the gap between slats before placing your Amerisleep mattress on a new or existing frame. If gaps exceed 2.75 inches, add slats or use a bunkie board. This is a common reason warranty claims are denied on otherwise legitimate defects.
Amerisleep warranty vs competitors
A 20-year warranty is above average for the mattress industry. Here is how Amerisleep stacks up against the brands most commonly compared to it:
| Mattress | Type | Firmness | Trial | Warranty | Queen price |
|---|---|---|---|---|---|
| Amerisleep AS3 | All-foam Bio-Pur | Medium 5/10 | 365 nights | 20 years (10 full + 10 prorated) | $1,149 (queen) |
| Nectar Classic | All-foam memory foam | Medium-firm 6.5/10 | 365 nights | Lifetime | ~$699 |
| Saatva Classic | Innerspring hybrid | 3 options: ~4/6/8 | 365 nights | Lifetime (free replacement years 1–2, then repairs with a $149 fee) | $2,229 |
| Helix Midnight | Hybrid | Medium 6/10 | 365 nights | Lifetime | ~$1,099 |
| Casper Original | All-foam | Medium-firm 6/10 | 100 nights | 10 years | ~$799 |
| Tempur-Pedic Cloud | All-foam TEMPUR | Medium 5/10 | 90 nights | 10 years | ~$1,700 |
Compare what happens after the first decade as well as the headline term. Amerisleep’s second decade is prorated, so a late claim can involve a replacement charge.
For most buyers, the 10-year full-coverage window is what matters most. Mattresses rarely develop qualifying defects after year 10 on a proper foundation. The 20-year prorated tail is a nice secondary benefit, but the first decade of full replacement coverage is the real value.
Frequently asked questions
How long is the Amerisleep warranty?
The mattress warranty runs for 20 years. The first ten provide full replacement coverage for qualifying defects; the second ten are prorated. Transport or labor charges may still apply.
What does "prorated" mean in the Amerisleep warranty?
Prorated coverage means you share the replacement cost during years 11–20: Amerisleep's terms set it at 50% of the original purchase price, plus shipping and labor. Confirm the amount due on your approved claim before agreeing to a replacement.
Does the Amerisleep warranty cover normal body impressions?
No. Normal body impressions (the slight softening and conforming of foam to your body shape over time) are not covered. The warranty only activates when visible sagging exceeds 1.5 inches measured on an unloaded mattress surface. Impressions under that threshold, even if visible, are considered normal wear.
Can I transfer the Amerisleep warranty if I sell the mattress?
No. The Amerisleep warranty is non-transferable. It applies only to the original buyer listed on the purchase order. If you sell or give the mattress to someone else, the warranty does not transfer to the new owner.
What photos do I need to file a warranty claim?
For sagging claims: photograph the mattress unloaded with a straight edge across the surface showing the gap, plus a close-up measurement of the sag depth. For manufacturing defect or separation claims: clear photos of the affected area from multiple angles in natural light. Include your order confirmation in the documentation package.
Does the warranty cover the mattress cover?
Yes, if the cover separates from the foam layers due to a workmanship defect. However, damage caused by removing the cover yourself is explicitly excluded. Do not attempt to unzip or remove the Amerisleep mattress cover; if there is a cover issue, contact Amerisleep customer service before touching it.
What foundation do I need to keep the warranty valid?
A slatted foundation with slats no more than 2.75 inches apart, a solid platform base, or a box spring in good condition. Broken frames, sagging foundations, and slatted frames with gaps wider than 2.75 inches void the warranty. Check your slat spacing before setup; gaps over 2.75 inches are the most common avoidable warranty-voiding mistake.
How does the Amerisleep warranty differ from the 365-night trial?
They are completely separate programs. The 365-night trial is a satisfaction guarantee: if the mattress is not right for you within 365 nights, you return it for a full refund. The warranty covers manufacturing defects and sagging that develop over the 20-year life of the mattress. You cannot use the warranty to return a mattress you simply do not prefer; that is what the trial is for.
Is the Amerisleep warranty valid if I bought through a retailer?
Warranty fulfillment for mattresses purchased through authorized third-party retailers may differ from direct amerisleep.com purchases. Contact Amerisleep customer service with your retailer receipt to verify warranty eligibility and the claim process for your purchase channel.
How does Amerisleep's 20-year warranty compare to Saatva's lifetime warranty?
Amerisleep’s 20-year term changes to prorated coverage after year 10. Compare that cost-sharing arrangement with the lifetime terms described above when deciding what long-term coverage is worth to you.
Amerisleep's 20-year warranty is solid, stronger than most brands, with full replacement coverage for qualifying defects in years 1–10; transport or labor charges may apply. The practical requirements are simple: keep your order confirmation, measure sag correctly on an unloaded mattress, and verify your foundation's slat spacing before setup. If you do those three things, the warranty works exactly as advertised.
