by Amerisleep AS3 vs IKEA Mattresses (2026): Side-by-Side Comparison
One brand builds a single medium-feel foam mattress with a 100-night trial. The other sells a whole aisle of spring, foam and hybrid options with a different return process. Here is how the two buying experiences actually compare.
The Amerisleep AS3 is our top pick here. It is one medium-feel all-foam mattress designed to balance support and softness for every sleep position, with a 100-night trial, a 20-year warranty, and free shipping and returns. IKEA is a retailer with a broad lineup of spring, foam and hybrid mattresses in many firmness levels, which is useful if you want to shop in person or compare many options side by side. The trade-off is that IKEA's return window depends on whether the mattress is opened, and you have to evaluate each model yourself. If you want a single, clearly specified mattress with a straightforward trial and warranty, choose the AS3. If you want to lie on several mattresses in a store first, start at IKEA and check the current return terms before you buy.
Amerisleep AS3
A medium-feel all-foam bed that Amerisleep builds to balance support and softness for every sleep position.
Saatva Classic
- Three comfort levels (Plush Soft, Luxury Firm, Firm) and two heights let you dial in the feel
- 365-night home trial is longer than the AS3's 100 nights
- Lifetime warranty covers the mattress for as long as you own it
- Free white-glove delivery includes setup and old-mattress removal
- Innerspring construction isolates motion less than an all-foam bed like the AS3
- You pick from three fixed comfort levels rather than one medium feel
- Delivery is scheduled rather than shipped in a box
The Saatva Classic is an alternative if you want an innerspring feel, a longer trial, and white-glove delivery with your old mattress hauled away. It earns the runner-up spot here because the AS3's medium-feel all-foam build is a simpler answer for shoppers who just want one well-rounded mattress.

Construction and materials
The Amerisleep AS3 is an all-foam mattress built around Bio-Pur foam. It is a single construction in a medium feel, designed to balance support and softness so it works across sleep positions rather than forcing you to choose between a firm or a soft model.
IKEA does not sell one mattress; it sells a catalog. The current US lineup includes pocket spring, memory foam, and foam models, with listings labeled firm or medium firm and some marked for cooling. Popular models in the range include VALEVÅG, VESTERÖY, ÅNNELAND, VÅGSTRANDA, and ÅBROTTEN, among others, and several are offered in multiple sizes and firmness levels.
That variety is the point. If you already know you want pocket springs versus foam, or you want to compare a firm model against a medium firm one, IKEA gives you the options. If you would rather have one mattress in a medium feel, the AS3 is the simpler path.
Feel and firmness
The AS3 has a medium feel. Amerisleep builds it to balance support and softness for every sleep position, so you are not choosing between a firm and a soft version. It is one feel, clearly stated.
IKEA's firmness varies model by model. Listings in the current range are labeled firm or medium firm, and several models are offered in more than one firmness level. There is no single "IKEA feel" to evaluate. Before you buy, check the firmness label on the specific model you are considering, and if you can, lie on it in a store. That is one genuine advantage of buying from a retailer with physical locations.
Pressure relief
Pressure relief is about how well a mattress cushions your hips, shoulders, and other contact points so you are not waking up sore. The AS3's Bio-Pur foam and medium feel are built to give that cushioning without letting you sink too far.
With IKEA, pressure relief depends entirely on which model you pick. A firm pocket spring mattress and a memory foam mattress will feel very different at the shoulder and hip. Check the construction type and firmness label on the specific model, and note that some listings are marked cooling. If pressure relief at the hips and shoulders is your main concern, compare a few models in person rather than assuming one IKEA mattress behaves like another.
Cooling
The AS3 uses Bio-Pur foam.
IKEA's cooling story varies by model. Some foam and memory foam listings in the current range are explicitly marked cooling, while others are not. If you sleep hot, filter the lineup for models with that label and check what the product page says about the materials. Also consider construction: pocket spring models tend to allow more airflow through the mattress than solid foam blocks.
Motion isolation
Motion isolation matters if you share a bed. All-foam mattresses like the AS3 generally absorb movement well, so a partner tossing and turning is less likely to transfer across the surface. That is one of the quieter advantages of a foam build.
IKEA's range includes both foam and pocket spring models. Foam models will typically isolate motion better than spring models, though pocket springs are designed to reduce motion transfer compared with traditional linked coils. If you are a light sleeper sharing a bed, lean toward a foam model in the IKEA lineup and check the construction type before you buy.
Trial period and warranty
Amerisleep backs the AS3 with a 100-night trial and a 20-year warranty, plus free shipping and returns. That means you have a defined window to decide the mattress is not right, and returning it does not cost you extra.
IKEA's return policy is structured differently. IKEA offers a 365-day return policy for unopened products. Open products can be returned within 180 days with proof of purchase for a full refund. Returns are handled at the Exchanges & returns desk in an IKEA store; for items delivered from a store, you contact the Customer Support Center to schedule a pickup. Returns are not accepted at IKEA Planning Studio or IKEA Pick Up Point locations.
The practical takeaway: the clock on an IKEA return depends on whether the mattress is opened. If you open and sleep on it, you are working with the 180-day window rather than the 365-day one, and you need your proof of purchase. With the AS3, the 100-night trial applies to the mattress you are actually sleeping on, with free returns. For warranty terms on a specific IKEA model, check the warranty documentation that ships with the product or ask the retailer directly, since terms can differ by model.
Price and value
We do not list prices on this page because they change with sales, sizes, and promotions. What matters for value is what you get for your money: a defined trial, a stated warranty, and a clear return process.
The AS3 gives you a 100-night trial, a 20-year warranty, and free shipping and returns on a single, clearly specified mattress. IKEA gives you a wide range of models at many price points, a 365-day return window for unopened products and 180 days for opened ones with proof of purchase, and the option to see the mattress in person before buying. Neither is objectively better value; they are different value propositions. Decide whether you would rather have one mattress with a straightforward policy, or the ability to browse and compare many options with a return process that depends on the product's condition.
Who should buy each mattress
Buy the Amerisleep AS3 if: you want one medium-feel all-foam mattress that balances support and softness for any sleep position, you prefer shopping online for a single clearly specified model, and you want a 100-night trial with a 20-year warranty and free shipping and returns. It is a good fit if you share a bed and want the motion-absorbing qualities of foam, or if you simply do not want to compare a dozen models before deciding.
Buy from IKEA if: you want to see and lie on mattresses before committing, you already know you prefer pocket springs or foam, or you want to browse many firmness levels and sizes in one place. It is also worth considering if the ability to return an unopened product within 365 days, or an opened one within 180 days with proof of purchase, fits how you like to shop. Before you buy, check the specific model's construction, firmness label, warranty terms, and current return conditions with the retailer.
The Amerisleep AS3 is one medium-feel all-foam mattress built to balance support and softness, with a 100-night trial, a 20-year warranty, and free shipping and returns. IKEA is a starting point if you want to shop in person, compare many models, or choose a specific construction and firmness yourself. Just check the return terms for the exact condition of the product and the warranty for the specific model before you buy. If you want the simpler, clearly specified option, choose the AS3.
