Amerisleep AS5 Hybrid Mattress Reviews (2026)

The AS5 Hybrid is worth considering if pressure relief is your first priority and you genuinely enjoy a soft mattress. Its Bio-Pur and Active Flex comfort layers create a deep cradle, while the pocketed coils keep the surface easier to move across than most slow-response foam beds. Side sleepers received the clearest benefit: shoulders settled without feeling pinched, and the hips stayed cushioned through long stretches on one side.

This is not a versatile medium-feel bed. Stomach sleepers can feel their hips dip out of line, and back sleepers who prefer a firm surface may miss stronger lumbar support. The plush perimeter also compresses noticeably when you sit on it. For the right sleeper, however, the combination of pressure relief, quiet partner performance, and a more responsive feel makes the AS5 Hybrid a compelling soft hybrid.

Who it’s for

• Side sleepers who need generous cushioning at the shoulders and hips
• Couples who want strong motion isolation without choosing an all-foam mattress
• Combination sleepers who prefer a soft surface but do not want to feel stuck

Who should skip it

• Strict stomach sleepers who need firmer support beneath the hips
• Back sleepers who prefer a flat, supportive feel with minimal sink
• Anyone who regularly sits on the edge and wants a rigid perimeter

Four testers followed our mattress testing process and rotated through back, side, and combination sleeping over several weeks. Each person followed the same routine, including long side-sleeping intervals, time spent lying on the back, repeated position changes, and sitting and lying near the perimeter. We also checked surface temperature, recovery after compression, and movement across the bed. Every performance category—support, cooling, pressure relief, motion isolation, responsiveness, edge support, and durability—uses the same 5-point scale.

After 48 hours of expansion, our sample measured 13.9 inches tall. The team’s average firmness rating was 3.5 out of 10, close to Amerisleep’s 3-out-of-10 soft designation. The first sensation was a deep, even cradle rather than springy lift. On my back, my hips settled lower than they do on a medium hybrid, but the coil system kept the mattress from feeling flat. Rolling onto my side brought the design into focus: the shoulder sank in gradually, pressure around the outer hip eased, and the surface stayed stable beneath the waist.

Mia, our most consistent side sleeper, had the best alignment of the group. Her shoulder had enough room to settle without forcing her neck upward. Marcus liked the cushioning in short back-sleeping sessions but felt his hips drop too far after a full night. Position changes were easier than expected for such a soft mattress; Active Flex and the coil core helped the comfort layers regain shape without the slow pull common to dense memory foam.

Heat control was good, not exceptional. The surface rose 5.6°F after 30 minutes of lying still and cooled to within 1.8°F of its starting temperature 10 minutes after we got up. Partner movement was better controlled: after a 10-pound ball was dropped from 6 inches on one side, vibration on the opposite side settled in an average of 0.8 seconds across three drops. The perimeter was the weaker result. Under the same 150-pound load, it compressed 1.2 inches more at 2 inches from the edge than it did in the center, matching the softer feel we noticed while sitting.

What we liked

• Deep, even pressure relief around the shoulders and hips during side sleeping
• Enough rebound to make turning easier than it is on many soft all-foam beds
• Quiet partner performance that keeps most movement close to its source

Who it is best for

• Dedicated side sleepers, especially those who feel pressure on firmer mattresses
• Couples who want a soft surface without frequent motion-related wake-ups
• Lightweight and average-weight back sleepers who enjoy a deep cradle

Where it falls short

• Stomach sleeping allows too much hip sink for dependable alignment
• The edge feels secure enough while lying down but compresses when seated
• Very hot sleepers may still notice warmth in the thick foam comfort system

• Mattress type: soft hybrid
• Profile: 14 inches
• Brand firmness: 3/10 (soft)
• Comfort system: open-cell Bio-Pur memory foam and responsive Active Flex foam
• Support system: individually wrapped coils over a stabilizing foam base
• Cooling features: Refresh cover, open-cell foam, and airflow through the coil core
• Sleep trial: 100 nights; Amerisleep asks customers to try the mattress for at least 30 nights before starting a return
• Warranty: 20 years
• Shipping and returns: free within the contiguous United States
• Materials: fiberglass-free; polyurethane foams are CertiPUR-US certified
• Origin: made in the USA from domestic and imported components; covers are sewn in Canada
• Foundation: use a solid or slatted base with gaps no wider than 2.75 inches; do not use a box spring

Choose the AS5 Hybrid if you spend most of the night on your side and prefer a clearly soft mattress. It also makes sense for couples who value motion isolation but want more lift than a traditional memory foam bed provides. Combination sleepers can move without much resistance, although anyone who regularly rolls onto the stomach should think twice.

Body weight changes the experience. Lightweight sleepers are more likely to receive cushioning without excessive sink, while heavier back sleepers should pay close attention to hip position during the trial. Hot sleepers will find the hybrid build more breathable than a comparable all-foam mattress, but the thick comfort stack is not the coolest option available.

Two close alternatives serve slightly different needs. The Helix Sunset Luxe is another soft hybrid for side sleepers, but its zoned lumbar support and firmer perimeter give it a more structured feel. The Nolah Evolution offers three firmness choices, making it the safer option when two sleepers agree on the features they want but not on an ultra-soft feel.

The AS5 Hybrid is soft by design, so its main limitation cannot be fixed with a different foundation or a longer break-in period. Stomach sleepers and back sleepers who need a level surface beneath the hips should choose a firmer mattress. The perimeter also feels softer while seated than the coil construction might suggest, and very warm sleepers may prefer a thinner comfort system with less foam around the body.

The AS5 Hybrid remains the best fit of this group for shoppers who want the deepest foam cradle and the strongest emphasis on side-sleeping pressure relief. Its motion isolation also gives it an advantage for couples who are easily disturbed. The alternatives below make more sense when you want a softer bed but need more structure, more firmness choices, or a springier surface.

Helix Sunset Luxe: This 13.5-inch soft hybrid is the closest match to the AS5 Hybrid. It adds zoned lumbar support and a reinforced perimeter, so it feels more controlled through the middle and steadier at the edge. Choose it if you want a plush pillow top but worry that the AS5 Hybrid will let your hips sink too far.

Saatva Classic Plush Soft: Saatva’s 3-out-of-10 option pairs a cushioned Euro top with a responsive dual-coil system. It feels springier, offers stronger seated-edge support, and includes in-room setup, but it does not absorb partner movement as thoroughly as the foam-forward AS5 Hybrid. It is the better choice for sleepers who want plushness without a deep memory-foam hug.

Nolah Evolution: The current 14-inch Evolution comes in Plush, Luxury Firm, and Firm. Its zoned foam and coils provide more firmness flexibility than the AS5 Hybrid, and the optional cooling pillow top appeals to hot sleepers. Choose it when you like a premium hybrid build but are not certain that an ultra-soft mattress is right for you.

• Use the full 30-night adjustment period before deciding whether the deep cradle suits you.
• Choose a side-sleeping pillow that fills the space between your head and the mattress without tilting your neck upward.
• Use breathable sheets and a lighter comforter if you tend to sleep warm.
• Rotate the mattress from head to foot every three to six months to promote even wear; do not flip it.
• Sit a few inches in from the perimeter if you want a steadier surface while getting dressed.
• Place the mattress on a solid platform or slats spaced no more than 2.75 inches apart.
• If your lower back feels strained while lying on your back, place a thin pillow beneath your knees and reassess your alignment.
• Use separate blankets if a partner’s tugging, rather than mattress movement, interrupts sleep.
• Add a breathable mattress protector early to keep the cover clean without trapping unnecessary heat.
