Suissly Firm Mattress Review
A Dunlop latex-and-foam hybrid built firm for back and stomach sleepers, made from nearly all-organic, earth-friendly materials.
One of the most comfortable firm mattresses we've tested.
Our reviewerA Firm Bed With Just Enough Give
The Suissly Firm pairs a Dunlop latex top with a high-density foam base for a firm bed that still finds a little softness, rather than feeling like a plank.
It rates 7 out of 10 on firmness. Oddly, it felt softer than Suissly's own Medium at first, then firmed up the longer we laid on it — landing as a bed best suited to back sleepers, and possibly too firm for side sleepers, who we'd point toward the Suissly Medium instead.
The memory foam middle layer disperses weight evenly over the high-density foam beneath, giving genuinely good joint relief by easing pressure points.
Sinkage measured about 1 inch at the center — this isn't a bed that hugs the body — but the latex top does a good job killing horizontal motion transfer, so couples can move around without disturbing each other.
We found no heat retention issues, which tracks with latex-topped beds generally, and no off-gassing beyond the faint smell most box mattresses have that clears within a few hours. Suissly's construction is also almost entirely organic.
At $999 for a queen, it lands a touch above the industry average, but the imported natural latex and premium materials make a solid case — especially for back and stomach sleepers, larger individuals, and anyone shopping for an earth-friendly bed.
Why We Love It
- Excellent joint relief from the memory foam over high-density foam combination
- Latex top significantly reduces motion transfer — good for couples
- No heat retention or off-gassing issues
- Nearly all organic and recycled materials, backed by a 10-year warranty
Considerations
- May be too firm for side sleepers, who can feel hip and shoulder compression
- Minimal contouring at just 1 inch of sinkage — won't hug the body
- At $999 for a queen, priced a bit above the industry average
Sleeping on the Suissly Firm Mattress
The combination of Dunlop latex and memory foam gives this bed a notable feel: it starts out softer than Suissly's Medium mattress, then firms up the longer you lie on it, ultimately landing as a firm, back-sleeper-friendly bed.
The memory foam layer disperses weight evenly over the high-density foam beneath, easing pressure points for excellent joint relief.
Sinkage measured around 1 inch at the center — there's a little contouring, but this mattress won't hug your body. The top latex layer does reduce horizontal motion well, so sleepers can move around without disturbing a partner.
Not Recommended for Side Sleepers
We aren't sure we'd recommend this bed for side sleepers, as the firmness may compress the hip and shoulder. Suissly's Medium mattress is a better fit for that sleep position.
We Recommend This To Readers Who:
-
Want a much firmer mattress
The 7/10 firmness rating delivers real, structured support.
-
Are back or stomach sleepers, especially larger individuals
The high-density foam base provides the support these sleep positions need.
-
Want an earth-friendly mattress
Every part of the Suissly is either 100% organic or recycled.
