by Amerisleep Retailers 2026: Where to Buy AS3, AS5 In-Store & Online
Amerisleep mattresses are available direct, through select Costco locations, and at a limited number of Mattress Firm stores. Here is exactly where to buy, what each channel offers, and where pricing is best.
TL;DR — Best Place to Buy Amerisleep in 2026
For most buyers: Amerisleep.com. You get all models, the full 100-night trial, a 20-year warranty, free shipping and returns, and an active 30% discount code that makes every mattress significantly cheaper than any third-party retailer. The AS3 queen runs $1,449 before discount; with the 30% promo it drops to roughly $1,014. No Costco price or floor-model deal beats that combination. The only exception: Costco members on a tight budget who want a one-time return convenience and can live with a limited model selection and a 90-day return window instead of 100 nights.
What this guide covers
Where Amerisleep Is Sold
Amerisleep is a direct-to-consumer mattress brand that keeps its retail footprint intentionally narrow. Unlike Serta, Sealy, or Tempur-Pedic, Amerisleep does not wholesale through a large network of furniture stores or department stores. There are five channels where you can purchase an Amerisleep mattress in 2026:
- Amerisleep.com — the primary sales channel, all models, best pricing
- Amerisleep showrooms — four owned-and-operated locations in Arizona and Texas for in-person testing
- Costco — limited model selection, Costco-exclusive pricing, Costco return policy
- Mattress Firm — select store locations carry Amerisleep display stock
- Sleepy's / Sleep Number select markets — occasional availability in specific regional markets
That is the complete list. Amerisleep mattresses are not carried by Amazon (authorized), Wayfair, Target, or general furniture retailers. Any listing you find on those platforms is either an unauthorized reseller or a different brand. Buying outside the five channels above voids the warranty and trial period.

Amerisleep.com: The Primary Channel
Amerisleep.com Best for most buyers
URL: amerisleep.com — Models: AS1, AS2, AS3, AS4, AS5, Organica, AS3 Hybrid, AS5 Hybrid — Trial: 100 nights — Warranty: 20 years — Shipping: Free — Returns: Free
Buying direct gives you access to the full lineup, the longest trial, and the manufacturer warranty. The 20-year warranty is one of the strongest in the foam mattress category — most competitors offer 10 years. The 100-night trial begins the day of delivery and allows a full refund on returns; Amerisleep coordinates the pickup so you do not need to transport the mattress yourself.
Promotions are the decisive factor. Amerisleep.com runs a 30% off sitewide discount reliably around major holidays (Memorial Day, Labor Day, Black Friday), and as of early 2026, the promotion has been running continuously. No physical retailer or Costco pricing consistently beats the discounted Amerisleep.com price once that promotion is active.

Amerisleep Showroom Locations
Amerisleep operates four company-owned showrooms in the Southwest United States. These showrooms exist for in-person testing only — you can try every model before ordering. Final purchases are processed at website pricing through the Amerisleep.com system, so you get the same price, trial, and warranty as ordering online.
Scottsdale, AZ
Open Monday–Saturday, hours vary. Call ahead to confirm availability of specific models.
Phoenix, AZ
Open Monday–Saturday. All AS1–AS5 models on display.
Houston, TX
Open Monday–Saturday. Full model lineup available for testing.
Amerisleep has periodically opened and closed pop-up showrooms in other Southwest cities. Check amerisleep.com/showrooms for current confirmed addresses before making a trip. MattressNut verifies showroom addresses quarterly via direct contact with Amerisleep.
Amerisleep at Costco: What Is Actually Available
Costco Limited selection
Models: AS3-equivalent (foam, medium firmness) — Trial: 90 days (Costco return policy) — Warranty: Per Costco terms — Price: Approximately $1,229–$1,299 queen
Costco carries what is effectively an AS3-specification mattress under a Costco-exclusive SKU. The mattress uses Amerisleep's Bio-Pur foam construction and performs comparably to the standard AS3, but it is sold as a Costco-branded item rather than a named AS3. This matters for two reasons: the Amerisleep 20-year manufacturer warranty does not apply (Costco's own return and warranty terms govern), and you cannot compare the Costco model to the AS3 specification sheet on a one-for-one basis.
Costco pricing in context: At $1,229 to $1,299 queen, Costco pricing is roughly 10 to 15 percent below Amerisleep MSRP. However, with the 30% off sitewide promotion running at Amerisleep.com, the direct-site price drops to approximately $1,014 queen. That means Amerisleep.com's discounted price is $215 to $285 lower than Costco's "deal" pricing. The Costco purchase makes financial sense only if you cannot access or do not want to use the Amerisleep.com promotion.
Costco return policy: Costco allows returns on mattresses within 90 days. This is more restrictive than Amerisleep.com's 100-night trial. The practical difference: 90 days gives you three months to evaluate versus just over three months with the direct site. For most buyers this is not a meaningful gap, but if you tend to need extended adjustment periods, the 100-night trial has real value.
Costco availability: Not all Costco locations carry Amerisleep stock. Availability varies by warehouse and changes seasonally. Costco.com has more consistent availability than in-club floor display. Check Costco.com before visiting a warehouse.
Amerisleep at Mattress Firm
Mattress Firm Select locations only
Models: Select (varies by store, typically AS3 and one hybrid) — Trial: 120 nights (Mattress Firm Sleep Trial) — Warranty: 20-year Amerisleep manufacturer warranty — Price: MSRP (no promotional discount)
A subset of Mattress Firm locations carry Amerisleep floor models. This is not a chainwide distribution arrangement — store-level availability varies significantly by region. Mattress Firm stores in Phoenix, Houston, and select Southwest markets are more likely to carry Amerisleep stock given Amerisleep's geographic concentration. Call your local Mattress Firm to confirm availability before visiting.
Mattress Firm trial vs. direct: Mattress Firm offers its own 120-night Sleep Trial on qualifying mattresses, which is longer than Amerisleep.com's 100-night trial. However, the exchange and return process through Mattress Firm involves an in-store transaction rather than Amerisleep's direct pickup service. If you need an exchange due to firmness preference (e.g., want to swap an AS3 for an AS4), Mattress Firm's process differs from the direct-to-consumer model. Read Mattress Firm's current trial terms before purchasing.
Pricing at Mattress Firm: Mattress Firm sells Amerisleep at MSRP. No independent promotional discount from Amerisleep.com applies at Mattress Firm. The AS3 queen lists at $1,449 and the AS5 at $1,849. If you plan to purchase at Mattress Firm, ask whether any current in-store promotions or bundle pricing applies to your specific order date.
In-store delivery advantage: One genuine benefit of purchasing through Mattress Firm is coordinated same-day or next-day delivery in markets where Mattress Firm has local distribution infrastructure. If you need a mattress on a specific date and Amerisleep.com's shipping timeline does not accommodate it, Mattress Firm may offer faster local delivery.
Other Retailers: Sleepy's and Select Markets
Sleepy's (now integrated into Mattress Firm) and a small number of regional sleep specialty retailers occasionally carry Amerisleep models in select markets. This distribution is not consistent or chainwide. If you see an Amerisleep mattress at a retailer not listed above, verify the following before purchasing:
- Confirm the retailer is an authorized Amerisleep dealer (contact Amerisleep directly at amerisleep.com/contact)
- Verify the 20-year manufacturer warranty applies through that retailer
- Confirm the trial period and return process
- Compare the in-store price to the current Amerisleep.com promotional price
Unauthorized third-party Amazon listings for Amerisleep mattresses exist and should be avoided. Amazon does not have an authorized Amerisleep distribution agreement, and purchases through those listings void the warranty and trial period.

Frequently Asked Questions
Is Amerisleep sold at Costco?
Yes, Costco carries an Amerisleep foam mattress in a limited selection, typically an AS3-specification medium-firmness model. Availability varies by Costco warehouse location. The Costco version is sold under Costco's own terms — Costco's 90-day return policy applies, not Amerisleep's 100-night trial — and the Amerisleep 20-year manufacturer warranty may not apply directly through Costco. Pricing at Costco runs approximately $1,229 to $1,299 for a queen, which is below Amerisleep MSRP but typically higher than Amerisleep.com during active 30% off promotions.
Is Amerisleep sold at Mattress Firm?
Select Mattress Firm locations carry Amerisleep floor models. This is not a chainwide arrangement — availability depends on your local market, with better availability in Southwest US cities like Phoenix and Houston. Pricing at Mattress Firm is at MSRP with no Amerisleep.com promotional discounts applied. Call your local store before visiting to confirm Amerisleep is in stock.
Can I buy Amerisleep on Amazon?
Amerisleep does not have an authorized Amazon distribution agreement. Listings you find on Amazon are from third-party sellers and are not authorized. Purchasing through those listings voids the Amerisleep warranty and trial period. Buy only through amerisleep.com, an Amerisleep showroom, or a confirmed authorized retailer.
Where are Amerisleep showrooms located?
Amerisleep operates showrooms in Scottsdale, AZ (HQ), Phoenix, AZ, and Houston, TX, plus occasional locations in other Southwest US cities. Showroom purchases are processed at website pricing, so you receive the same trial, warranty, and shipping terms as ordering online. Visit amerisleep.com/showrooms for current confirmed addresses before making a trip.
Is Amerisleep cheaper at Costco than on their website?
At MSRP, Costco pricing is approximately 10 to 15 percent lower. However, Amerisleep.com regularly runs a 30% off sitewide promotion that brings the AS3 queen from $1,449 to approximately $1,014. That discounted price is $215 to $285 lower than Costco's typical pricing. Check Amerisleep.com's current promotions before purchasing at Costco.
Does Costco carry the AS5?
No. Costco's Amerisleep offering is limited to a medium-firmness foam mattress comparable to the AS3. The AS5 (soft, 3.5/10 firmness) is not available through Costco. To purchase an AS5, you need to order through Amerisleep.com, a showroom, or a Mattress Firm location that carries it.
What is the return policy if I buy Amerisleep at Mattress Firm?
Mattress Firm's own 120-night Sleep Trial policy applies. This is longer than Amerisleep.com's 100-night trial. However, the exchange process differs: exchanges and returns are handled through Mattress Firm's in-store system rather than Amerisleep's direct pickup service. Review current Mattress Firm trial terms at the time of purchase, as specific conditions vary.
Does buying from a retailer affect the Amerisleep warranty?
It depends on the retailer. Purchasing through an authorized retailer (confirmed Mattress Firm locations carrying Amerisleep stock) preserves the 20-year Amerisleep manufacturer warranty. Purchasing through Costco substitutes Costco's own warranty terms. Purchasing through unauthorized third-party sellers (Amazon resellers, unapproved dealers) voids the Amerisleep warranty entirely. When in doubt, confirm authorization with Amerisleep directly before purchasing.
Can I try an Amerisleep mattress in person before buying?
Yes, through two channels: Amerisleep's own showrooms in Phoenix, Scottsdale, and Houston, and select Mattress Firm locations that carry floor display models. The showroom experience is preferable because all models are on display and staff are trained specifically on Amerisleep's lineup. At Mattress Firm, model availability varies by store and floor staff may have limited Amerisleep-specific knowledge.
Which Amerisleep model is best for side sleepers?
The AS5 is Amerisleep's softest model (3.5/10 firmness) and is designed specifically for side sleepers who need shoulder and hip pressure relief. The AS3 at medium firmness (5.5/10) works for combination sleepers who also sleep on their side but need more support than the AS5 provides. See our full AS5 review and AS3 review for firmness-based comparisons.
Verdict: Where to Buy Amerisleep in 2026
Recommendation by buyer type
Most buyers: Amerisleep.com. The combination of all available models, a 100-night trial, a 20-year warranty, and an active 30% discount makes the direct site the best purchase option for the majority of people. There is no retailer in 2026 that consistently beats Amerisleep.com's discounted price while also matching the warranty and trial length. Order online, use the current promotion, and take advantage of the free return pickup if the mattress is not right.
Costco members on a budget: If the limited AS3-equivalent model meets your needs and you are comfortable with Costco's 90-day return policy instead of 100 nights, Costco is a reasonable secondary option at a non-promotional price. Do the math before purchasing — if Amerisleep's 30% discount is active (check before buying), the direct site is cheaper.
Want to try before buying: Visit an Amerisleep showroom in Phoenix, Scottsdale, or Houston. You test every model and purchase at website pricing, so you get the in-person experience without sacrificing any purchase terms. Mattress Firm is an option if you live outside those cities, but call first to confirm Amerisleep floor stock at your specific location.
