What independent reviewers found
- Mattress Clarity (Sep 2026): Reviewers found its thick foam contained motion well despite a fairly responsive feel, but the edges collapsed a bit when sitting or lying near them. Some smell for a few days. Site discloses affiliate programs and free review products. Read it ↗
- NapLab (May 2026): Soft at 4/10; best for side sleepers, and any position under 150 lbs. Excellent cooling, very low motion transfer, softer sitting edge. Low bounce; odor lasted about 3 days; priced well above average memory foam. All-foam AS5. Site discloses affiliate commissions. Read it ↗
- Sleepopolis (Oct 2026): Testers averaged just under 6/10. Recommended for side sleepers and couples; the reviewer's hips sank when on his stomach. Motion isolation among the best he tested; edges felt secure. All-foam AS5. Conflicting update dates on page. Site discloses affiliate commissions. Read it ↗
- Sleep Foundation (Apr 2025): Rates it soft; suits side sleepers and people under 130 lbs. Motion isolation 9 and pressure relief 9, but temperature control 5; most back and stomach sleepers over 130 lbs may find it too soft. Brand-wide review; gives the AS5 firmness as 3 in one place and 4 in another. Discloses affiliate commissions. Read it ↗

Sources & sample limits
7 GoodBed owners: one written review (2020) and 6 ratings only Sample: 7 owner reports.
GoodBed entries are mostly ratings only, and the written one is from 2020, so it may be an earlier version.
Research checked October 14, 2026. These are sourced observations, not our own product tests or a star rating.
What owners report
Only a couple of reviews on Amerisleep's Trustpilot page name the AS5. One side sleeper with shoulder trouble found it soft yet supportive, cool and good at isolating motion; another said a king bought about ten years ago still performs. Complaints were about a bed frame, shipping time and the king's weight.
Owners like
- Soft but supportive for a side sleeper
- Still performing after about ten years
- Isolates motion and feels cool
Owners mention
- Heavy and bulky in king
- Slow shipping, damaged box
