What independent reviewers found
- NapLab (May 2026): Lab testers found the Medium-Firm side supportive in every sleep position across weight groups, with the plush side better suited to side sleepers. It slept cool, sitting edges held up well, it was very bouncy with more motion transfer than average, and a strong new-foam smell took about two weeks to fade. Tested the Medium-Firm and Plush options of the October 2025 update; firmer and medium feels were estimated, not tested. Affiliate commissions disclosed on page. Read it ↗
- GoodBed: Rated the M3 with 1.0 medium-firm coils a Medium (5) on its scale. Best for mainly back sleepers, couples wanting different feels per side, edge sitters and those who want to stay cool; not ideal over 225 lb, especially stomach sleepers. Medium-firm coil version; GoodBed earns from partner and cash-back offers. Read it ↗
Their testing, in our words. We haven’t tested these mattresses ourselves, and we don’t repeat their scores.
