by The best place to buy Amerisleep in 2026 is amerisleep.com direct: all models, a 100-night trial, a 20-year warranty, and an active sitewide discount that beats Costco and Mattress Firm pricing. For in-person testing, the company's own showrooms in Phoenix, Scottsdale, and Houston let you test every model and order at website pricing. Costco carries an AS3-equivalent at a lower sticker price, but once Amerisleep's 30% promotion is active, the direct site is cheaper.
Amerisleep AS3
9.1/10
- Best pricing when ordered direct at amerisleep.com, with a 30% sitewide discount active in 2026
- Full 100-night trial and 20-year warranty apply only through the direct channel
- HIVE 5-zone support system, CertiPUR-US certified, partially plant-based Bio-Pur foam
- Free shipping and free return pickup included
- No same-day delivery; ships FedEx with typical lead time of 3–7 business days
- Softer edges than a coil hybrid, so sleepers over 230 lb may prefer the AS5 Hybrid
The AS3 is Amerisleep's best-seller and the model most buyers are looking for. Ordering through amerisleep.com gets you the best price, the full warranty, and a hassle-free 100-night trial. It is the clear first choice before checking any third-party channel.
Where Amerisleep is sold in 2026
Amerisleep keeps its retail footprint intentionally narrow. Unlike Serta or Sealy, it does not wholesale through furniture chains or department stores. There are four channels where you can purchase an Amerisleep mattress in 2026:
- Amerisleep.com: the primary channel; all models, best pricing, full trial and warranty
- Amerisleep showrooms: four company-owned locations in Arizona and Texas for in-person testing
- Costco: AS3-equivalent model at Costco-exclusive pricing; Costco return policy applies
- Mattress Firm: select store locations carry floor display models; MSRP pricing, no Amerisleep.com discounts
Amerisleep mattresses are not carried by Amazon (authorized), Wayfair, Target, or general furniture chains. Any listing on those platforms comes from unauthorized resellers. Buying outside the four channels above voids the Amerisleep warranty and trial. For a full picture of every model before deciding where to buy, see our Amerisleep brand hub.
Retailer comparison: pricing, trial, and warranty
| Mattress / Retailer | Type | Firmness | Trial | Warranty | Queen price |
|---|---|---|---|---|---|
| Amerisleep.com AS3 | All-foam Bio-Pur (direct) | Medium 5/10 | 100 nights | 20 years | From $1,049 (30% off) |
| Costco AS3-equivalent | All-foam (Costco SKU) | Medium 5–6/10 | 90 days | Costco terms | ~$1,229–$1,299 |
| Mattress Firm AS3 | All-foam (floor display) | Medium 5/10 | 120 nights (MF policy) | 20 years | MSRP $1,449 |
| Amerisleep Showroom AS3 | All-foam Bio-Pur (in-store order) | Medium 5/10 | 100 nights | 20 years | Same as website |
Buying direct at amerisleep.com
Amerisleep.com is the default answer for most buyers. Every model in the lineup is available, AS1 through AS5, the Organica, the AS3 Hybrid, and the AS5 Hybrid, and the direct site is where the full 100-night trial and 20-year warranty apply without restriction.
Pricing is the decisive advantage. Amerisleep runs a sitewide discount reliably around every major sale window, and as of mid-2026 a 30% promotion has been running continuously. That brings the AS3 queen from $1,449 MSRP to approximately $1,014. No Costco price or Mattress Firm bundle consistently beats that once the discount is active. Before purchasing anywhere else, check current Amerisleep promo codes to confirm the live discount.
Shipping is free across the continental US via FedEx. Returns are free as well, Amerisleep coordinates mattress pickup so you do not need to transport it yourself. Financing is available through Klarna at 0% APR for qualifying purchases.
The one limitation of the direct channel is delivery time. Standard orders ship in three to seven business days. If you need a mattress on a specific date, Mattress Firm's local distribution can sometimes move faster. For everyone else, the direct site has no real competition.

Amerisleep showroom locations
Amerisleep operates four company-owned showrooms in the Southwest United States. These exist specifically for in-person model testing. You can lie on every mattress in the AS1–AS5 range before committing. Final purchases are processed at Amerisleep.com pricing, so showroom buyers receive the same trial, warranty, and shipping terms as ordering online.
The Scottsdale location functions as the brand's flagship. Phoenix and Houston are the other high-availability markets. Amerisleep occasionally opens and closes additional Southwest locations. Check amerisleep.com/showrooms before making a trip to confirm current hours and addresses.
If you are deciding between the AS3 and AS5, the showroom is genuinely useful. The firmness gap between those two models, medium at roughly 5.5/10 versus soft at roughly 3.5/10, reads as significant on a spec sheet but feels more concrete once you actually lie on both. For couples with different firmness preferences, spending 20 minutes testing motion transfer on both models in person is worth the drive.
For dedicated showroom guides with current hours and addresses, see our Houston showroom page and Scottsdale showroom page.
Amerisleep at Costco: what is actually there
Costco carries what is effectively an AS3-specification mattress under a Costco-exclusive SKU. The construction uses Amerisleep's Bio-Pur foam and performs comparably to the standard AS3, but it is sold as a Costco item rather than a named AS3 model. That distinction matters for two reasons.
First, the Amerisleep 20-year manufacturer warranty does not apply to the Costco version. Costco's own return and warranty terms govern. Second, you cannot compare the Costco model spec-for-spec to the AS3 on the Amerisleep website, because Costco does not publish the same construction details.
On pricing: Costco typically prices the mattress at $1,229 to $1,299 queen, roughly 10–15% below Amerisleep MSRP. That sounds appealing until you factor in the active Amerisleep.com discount. With a 30% off promotion running, the direct-site AS3 queen lands at approximately $1,014, which is $215 to $285 less than the Costco price. The Costco purchase only makes sense financially if you cannot use or do not want to use the Amerisleep.com promotion.
The other factor is the return window. Costco allows returns within 90 days. Amerisleep.com gives you 100 nights (just over three months). The practical gap is small, but if you tend to need a longer adjustment period, the 100-night trial has real value.
Not all Costco locations carry Amerisleep stock. Availability varies by warehouse and changes seasonally. Check Costco.com before driving to a warehouse.
Amerisleep at Mattress Firm
A subset of Mattress Firm locations carries Amerisleep floor models. This is not a chainwide arrangement. Store-level availability varies by region, with better coverage in Phoenix, Houston, and other Southwest markets where Amerisleep has its showroom presence. Call your local Mattress Firm to confirm Amerisleep is on the floor before visiting.
Pricing at Mattress Firm is at MSRP. No Amerisleep.com promotional discount applies through the Mattress Firm channel. The AS3 queen lists at $1,449 and the AS5 at $1,849. If the 30% Amerisleep.com discount is active, you are paying $430+ extra for the same mattress through Mattress Firm.
Mattress Firm does offer its own 120-night Sleep Trial on qualifying mattresses, which is 20 nights longer than the direct-site trial. That is a genuine structural difference. The exchange and return process runs through Mattress Firm's in-store system rather than Amerisleep's direct pickup service, so read the current Mattress Firm trial terms before purchasing, since conditions and fees vary.
The strongest case for Mattress Firm is delivery speed. In markets where Mattress Firm has local distribution infrastructure, same-day or next-day delivery is sometimes available. If a hard move-in date makes timing critical, Mattress Firm can solve a logistics problem that the direct site cannot. For everyone else, the price premium is hard to justify.
Where not to buy Amerisleep
Amerisleep does not have an authorized Amazon distribution agreement. Listings on Amazon come from third-party resellers. Purchasing through those listings voids the Amerisleep warranty and trial period entirely, and you have no recourse with Amerisleep if something goes wrong with the mattress.
The same applies to Wayfair, Target, and general furniture retailers. If you see an Amerisleep mattress on any platform not listed in this guide, verify authorization directly with Amerisleep (amerisleep.com/contact) before purchasing. Confirm the 20-year warranty and 100-night trial apply through that specific retailer before completing the transaction.
Where to buy Amerisleep in 2026: the verdict
For most buyers, the answer is amerisleep.com. The combination of all available models, a 100-night risk-free trial, a 20-year warranty, free shipping and returns, and an active 30% discount makes the direct channel the only realistic first choice in 2026. No retailer in the US consistently beats that package.
If you want to test in person first, the Amerisleep showrooms in Phoenix, Scottsdale, and Houston let you do that without giving up any purchase terms. You test on-site and order at website pricing.
Costco makes narrow sense for members who cannot or do not want to use the Amerisleep.com discount and are comfortable with the 90-day return window instead of 100 nights. Do the math first. If the 30% promotion is active, Costco is more expensive.
Mattress Firm is useful in two specific scenarios: you need same-day delivery that the direct site cannot accommodate, or you live outside Phoenix/Houston/Scottsdale and want to try an Amerisleep mattress in person before committing. Beyond those cases, the MSRP pricing at Mattress Firm does not compete with Amerisleep.com's active discount.
Buy at amerisleep.com for the best price, the full warranty, and the 100-night trial. The AS3 is the best-seller and the right starting point for most buyers. Check the current discount before looking anywhere else.
Frequently asked questions
Is Amerisleep sold at Costco?
Yes. Costco carries an AS3-equivalent foam mattress in limited quantities. Availability varies by warehouse. Costco's 90-day return policy applies, not Amerisleep's 100-night trial, and the Amerisleep 20-year manufacturer warranty does not extend to the Costco version. Pricing runs $1,229–$1,299 queen, which is typically more expensive than amerisleep.com once the active 30% discount is applied.
Is Amerisleep sold at Mattress Firm?
Select Mattress Firm locations carry Amerisleep floor models, mainly in Southwest US markets. Pricing is MSRP with no Amerisleep.com promotional discounts. Mattress Firm's own 120-night sleep trial applies. Call your local store before visiting, this is not a chainwide stocking arrangement.
Can I buy Amerisleep on Amazon?
No, not through an authorized seller. Amerisleep has no authorized Amazon distribution agreement. Third-party Amazon listings void the warranty and trial period. Purchase only through amerisleep.com, a company showroom, or a confirmed authorized retailer.
Where are Amerisleep showrooms located?
Amerisleep operates showrooms in Scottsdale, AZ (flagship), Phoenix, AZ, and Houston, TX, plus occasional other Southwest locations. Purchases at showrooms are processed at amerisleep.com pricing, so you receive the same trial, warranty, and shipping terms as ordering online.
Is Amerisleep cheaper at Costco than on the website?
At MSRP, Costco pricing is roughly 10–15% lower. But Amerisleep.com's active 30% discount brings the AS3 queen to approximately $1,014, which is $215–$285 less than Costco. Check amerisleep.com's current promotions before purchasing at Costco.
Does Costco carry the AS5?
No. Costco only stocks an AS3-equivalent medium-firmness model. The AS5 (soft, ~3.5/10) is available only through amerisleep.com, a company showroom, or an authorized Mattress Firm location that carries it.
Does buying from a retailer affect the Amerisleep warranty?
It depends on the retailer. Authorized retailers like select Mattress Firm stores preserve the full 20-year Amerisleep manufacturer warranty. Costco substitutes its own warranty terms. Unauthorized third-party sellers, including Amazon resellers, void the warranty entirely.
Which model should I buy?
The AS3 is Amerisleep's best-seller and suits most back and combination sleepers at medium firmness (roughly 5.5/10). Side sleepers who need deep shoulder pressure relief typically prefer the softer AS4 or AS5. Heavier sleepers and stomach sleepers usually do better with the firmer AS2 or the AS5 Hybrid for its coil support. See our AS3 review and AS5 review for side-by-side firmness comparisons.
