Some Beautyrest mattresses are good for heavy people, but most are not thick or supportive enough for bodies over 300 lbs.
The best specific Beautyrest models for heavy people include the Beautyrest Black, Beautyrest Black Hybrid, and Beautyrest Harmony Lux.

These three models are the thickest Beautyrest mattresses we’ve reviewed to date, and all offer slightly firm (7) to firm (8) firmness options.
The Black and Black Hybrid models are the highest tier the brand offers, which includes the thickest designs, densest foams, and more supportive coil units — specifically the series 3 and 4 versions.
For those who cannot afford the series 3 or 4 in the Black Collections, the Harmony Lux is the best option, due to its lower price, optional firmness, and more supportive coil unit.


That being said, not all heavy sleepers prefer the feel of a super firm mattress. For most heavier sleepers, medium-firm to firm mattresses can offer sufficient support.
