Suissly Medium Firm Mattress Review
A latex-and-coil hybrid built for back sleepers who want real push-back, wrapped around materials Suissly builds to be organic and low-impact.
Back sleepers will be in heaven with the medium firm mattress.
Our reviewerA Firmer Feel Built for Back Sleepers and Responsive Nights
The Suissly Medium Firm is one of those beds that could reasonably change how shoppers think about a box mattress. It pairs a latex top with an inner layer of pocket coils, producing a feel and a response we haven't found in other mattresses-in-a-box.
At a 7 out of 10 on our firmness scale, it reads firm at first touch, though it does soften slightly as it disperses a sleeper's weight. About 2 inches of sinkage keeps the surface from feeling like quicksand while still delivering real cushioning.
The pocket coils beneath the latex top are the standout: they add a springiness rarely found in traditional latex-and-foam beds, and that responsiveness paid off beyond just sleep. Back sleepers in particular found the support excellent.
We had no complaints on temperature or off-gassing. The latex top kept us cool regardless of room temperature, and the mattress arrived with no significant smell, a reflection of Suissly's focus on organic materials and earth-friendly manufacturing.
At $999 for a queen before discounts, it lands solidly in the middle of the mattress-in-a-box pack, backed by a 100-night trial, a 10-year warranty and free U.S. shipping.

Our Hands-On Review
This bed scored a 7 out of 10 on our firmness scale — firm at first touch, though it softens slightly as it disperses a sleeper's weight thanks to the pocket coils beneath the latex top. We recorded about 2 inches of sinkage, enough to cushion without ever feeling like quicksand.
Temperature was a non-issue: the latex top kept us cool regardless of room conditions, and we found no significant off-gassing on unboxing — notable for a brand this focused on organic, earth-friendly materials.
Built for More Than Sleep
The coils and top latex layer combine to give a responsiveness we haven't found in other box mattresses — good news for energetic couples, and enough to earn this bed a spot on our list of top mattresses for sex.
