I’m very happy with this purchase! It’s incredibly soft and comfortable while still providing a nice level of firmness and support. I’ve been sleeping really well on it. The only minor issue is that all four corners seem slightly compressed or sunken. I initially thought they would fully expand and return to their normal shape over time, but they still seem to be that way. Aside from the corners, I’m very satisfied with everything else. It’s comfortable, supportive, and I’ve been enjoying it so far. I would definitely recommend it!. Anonymous. Fri Oct 16 2026

[This review was collected as part of a promotion.] The quality of this mattress is excellent. It is a heavy, thick mattress with a soft and durable cooling cover. It feels like a mattress that will stand up to the test of time. I’ve had a few budget memory foam mattresses, and there is a marked difference in quality between those mattresses and this mattress. This mattress is soft, but it is definitely not plush. I would say it is medium firmness. When you lay on the mattress, it sinks in, but you do not melt into it. There is little to no motion transfer, so you do not feel your partner moving through the night. I love that there is a 100 night trial so you can shop with confidence.. Aprilb. Thu Feb 19 2026
