by Nectar Alternatives: Amerisleep AS3 and Saatva Classic Compared (2026)
Two strong replacements for shoppers moving off Nectar: a medium-feel all-foam bed from Amerisleep and a customizable innerspring from Saatva.
The Amerisleep AS3 is our top pick to replace a sagging Nectar. It is a medium-feel all-foam bed built to balance support and softness for every sleep position, with Bio-Pur foam, a 100-night trial, a 20-year warranty, and free shipping and returns. If you want coils instead of foam, the Saatva Classic is our runner-up.
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) so you can match the feel you are used to
- Two height options for different bed frames and preferences
- 365-night home trial gives you a full year to decide
- Lifetime warranty on the mattress
- Free white-glove delivery, including removal of your old mattress
- Innerspring construction moves more than all-foam, so light sleepers may notice a partner shifting
- White-glove delivery is scheduled rather than shipped in a box
The Saatva Classic suits shoppers who want a traditional innerspring feel. Its three comfort levels let you choose a firmness.
What Nectar is known for
Nectar sells memory foam mattresses and backs them with a 365-night home trial and a Forever Warranty on mattresses. The trial starts on the delivery date, and a return request on an opened mattress can be made no earlier than 30 days and no later than 365 days after delivery. Returns depend on the mattress being in a sanitary condition with no rips, stains, or signs of wear, and Nectar works with donation partners who assess eligibility on site.
The Nectar Premier Memory Foam Mattress is a 13-inch model the brand positions around pressure-relieving memory foam and a cool-to-the-touch cover. Shipping and returns are free. Nectar also offers a Forever Warranty on mattresses, which is non-transferable and valid only for the original purchaser, with coverage against defects in material and workmanship starting from the date of delivery.
Those terms are generous on paper, which is why Nectar is a common first purchase. A mattress that has started to sag is a comfort and support problem, and the right replacement depends on what you want next, not on what you had before.
Construction and materials
The Amerisleep AS3 is an all-foam mattress built around Bio-Pur foam. Amerisleep describes it as a medium-feel bed designed to balance support and softness for every sleep position, which makes it a straightforward swap for a memory foam mattress that has lost its shape. All-foam construction means there are no coils to transfer motion.
The Saatva Classic takes the opposite approach. It is an innerspring mattress with three comfort levels (Plush Soft, Luxury Firm, Firm) and two heights. Choosing a comfort level lets you decide how much give the surface has before you buy. Innerspring builds generally feel more responsive than foam.
Nectar's Premier model is a 13-inch memory foam mattress. Memory foam conforms closely to the body, which is what makes it good at pressure relief when it is new, and also what makes sagging noticeable once the foam loses resilience.
Feel and firmness
The AS3 has a medium feel.
The Saatva Classic does not have a single firmness. You pick Plush Soft, Luxury Firm, or Firm at checkout.
Pressure relief
Pressure relief is about how well a surface spreads load at the hips, shoulders, and lower back. The AS3's Bio-Pur foam is built to cushion those contact points while still supporting the midsection.
The Saatva Classic's Plush Soft and Luxury Firm comfort levels give cushion at the joints, while the Firm option keeps the surface more level. Because it is an innerspring, the support comes from the coil system rather than from foam conforming.
Cooling
Foam mattresses trap heat when the material is dense and closed off. The AS3 is an all-foam build with Bio-Pur foam, so weigh it against a coil build if heat is your main complaint.
The Saatva Classic's innerspring construction leaves more open space inside the mattress than a solid foam block.
Nectar's Premier model is marketed with a cool-to-the-touch cover, so cooling is a stated priority for the brand.
Motion isolation
All-foam mattresses isolate motion better than innerspring mattresses, because there are no coils to bounce a partner's movement across the surface. If you share a bed and your partner gets up at night, the AS3 will absorb that movement more than the Saatva Classic will.
The Saatva Classic, as an innerspring, transmits more movement.
Trial period and warranty
The Amerisleep AS3 comes with a 100-night trial and a 20-year warranty, with free shipping and returns. The trial is shorter than Nectar's 365 nights, so you have a tighter window to decide.
The Saatva Classic comes with a 365-night home trial and a lifetime warranty, matching Nectar's trial length. Delivery is free white-glove service, which includes setup and removal of your old mattress.
Nectar's mattress trial is 365 nights from delivery, with return requests accepted between day 30 and day 365 on opened mattresses, and its Forever Warranty covers defects in material and workmanship for the original purchaser. If your current Nectar is still inside its trial or warranty window, check your dates before you buy a replacement.
Price and value
We do not publish prices on this page. The AS3 pairs a 100-night trial with a 20-year warranty and free shipping and returns on an all-foam build. The Saatva Classic pairs a 365-night trial with a lifetime warranty and free white-glove delivery that includes old-mattress removal. Compare the trial length, the warranty, and the delivery service rather than the sticker price alone.
Who should buy each mattress
Buy the Amerisleep AS3 if: you want to stay on foam. It suits sleepers who want a medium feel, motion isolation from a partner, and a 20-year warranty. The 100-night trial and free returns make it a low-commitment swap.
Buy the Saatva Classic if: you want to leave foam behind for a traditional innerspring, or you want to choose your firmness. It suits sleepers who want a full 365-night trial, a lifetime warranty, and free white-glove delivery with the old mattress taken away. Pick Plush Soft, Luxury Firm, or Firm, and choose between the two available heights.
If your Nectar is sagging, our top pick is the Amerisleep AS3 : a medium-feel all-foam mattress with a 100-night trial, a 20-year warranty, and free shipping and returns. If you would rather have coils, a choice of three comfort levels, a 365-night trial, a lifetime warranty, and free white-glove delivery with old-mattress removal, the runner-up is the Saatva Classic .
Frequently asked questions
My Nectar is sagging. What should I replace it with?
The Amerisleep AS3 is our top pick. It is a medium-feel all-foam mattress built to balance support and softness for every sleep position, with Bio-Pur foam, a 100-night trial, a 20-year warranty, and free shipping and returns. If you want an innerspring instead, the Saatva Classic offers three comfort levels, two heights, a 365-night trial, a lifetime warranty, and free white-glove delivery with old-mattress removal.
Should I replace foam with foam, or switch to an innerspring?
Both are valid. Staying with foam (the AS3) keeps the motion isolation you are used to. Switching to an innerspring (the Saatva Classic) gives you a more responsive surface and a choice of three comfort levels. Your sleep position is one thing to weigh.
How long do I have to try a replacement?
The AS3 comes with a 100-night trial and the Saatva Classic with a 365-night home trial. Nectar's own mattress trial is 365 nights from delivery, with return requests on opened mattresses accepted between day 30 and day 365, so if your current mattress is still inside that window, check your dates first.
Does the Saatva Classic come with delivery and old-mattress removal?
Yes. Saatva includes free white-glove delivery, which covers setup and removal of your old mattress. The AS3 ships free with free returns.
Which alternative is better for couples?
The AS3, if motion isolation is your priority. All-foam construction absorbs a partner's movement instead of transferring it across coils. The Saatva Classic moves more, but it gives each sleeper a choice of comfort level.
