Think about

- A 250-300 lb side sleeper rated back support and pressure relief only 3 out of 5 after 4 years (Apr 2026).
- A 4-year owner of the cooling-cover version, sleeping on the firm side, called it moderately worn and rated support and pressure relief 3 out of 5 (Jan 2026).

Most Plank owners on GoodBed rate it well even after several years, though heavier sleepers and one firm-side owner gave middling scores.
What people liked
What independent reviewers found
- Sleep Foundation (Oct 2026): Testers found both sides very firm and stable, best for back and stomach sleepers over 230 pounds, with strong edges and a cooler surface than most foam beds; it gave little pressure relief for side sleepers and passed more motion than typical foam. Tested the standard home-size Brooklyn Bedding version, not an RV size. Page carries shop links and discount offers. Read it ↗
- Mattress Clarity (Oct 2026): Testers said it suits heavier and stomach sleepers, but lighter side sleepers felt it too hard, cooling was slightly below average, and the extra-firm side had the steadier edges and motion results. Tested the standard home-size Brooklyn Bedding version, not an RV size. Tested both sides. Site discloses affiliate programs and free review products. Read it ↗
Their testing, in our words. We haven’t tested these mattresses ourselves, and we don’t repeat their scores.
