AmeriSleep Colonial Mattress Review
A 13-inch, plant-based memory foam mattress built soft for pressure relief, with a Celliant cover engineered to turn body heat into infrared light.
Back sleepers might be surprised how good a sleep they get with a softer mattress.
Our reviewerA Soft Mattress That Still Delivers Real Support
AmeriSleep has been building mattresses in a box for over a decade, and the Colonial is one of its softest and tallest — a 4 out of 10 on the firmness scale, sitting on 11 inches of high-density foam beneath the surface.
Firmness and support get confused often, usually because of memories of old spring mattresses that sagged over time. That's not the case here: across sleeper types in our research, nobody reported aches or pains, and the soft Bio-Pur+ top still delivers real support underneath. Anyone who specifically prefers a firm mattress, though, should look elsewhere.
Sinkage lands around 2 inches, which is a solid result for a mattress this soft — sleepers can adjust position without disturbing a partner, thanks to minimal horizontal motion transfer.
Heat is the usual trade-off with soft foam beds, but AmeriSleep's Bio-Pur+ foam is engineered to be five times more breathable than standard memory foam, and the Celliant cover takes things further by converting body heat into infrared light. No off-gassing reports turned up either. Add it up and the total build reaches 13 inches — among the thickest mattresses we've come across.
At $2,049 for a queen, the Colonial isn't cheap, but a current $50 discount code softens that, and a 90-night trial with a 20-year warranty gives buyers real room to test it out.

What We Found in Our Research
Across the sleeper types covered in our research, the story was consistent — a soft top that still delivers real support, with no pattern of complaints about aches or pains. The 2-inch sinkage struck a comfortable balance for a mattress this soft, without sleepers disturbing each other when they moved.
The cooling claims held up too: Bio-Pur+'s five-times-more-breathable foam and the infrared-converting Celliant cover are both built specifically to counter the heat retention that soft foam mattresses are usually known for, and no off-gassing reports surfaced.
A Note on This Review
This review draws on AmeriSleep's specs and customer reports alongside our own findings — we've kept that framing transparent rather than overstating a single hands-on test.
