Review: Good bed for the price - I’ve had the bed for about 5 months now, great bed. Have no issues with temperature, comfort, fit or support. I am 6ft 250lbs. I got a queen size and it’s working out great. I’d say the only thing reviews were correct about is, sitting on the edge will cause you to slowly slip off the bed. Edges are much more softer than the center. Other than that, I sleep great and can’t complain.
Review: Firm but soft - First mattress I’ve purchased in about 10 years and I love it. Size is a king and my sleep quality is amazing. I’m a hot sleeper and it is very cooling. Suitable for kids as well. I purchased the full size mattress for my kid.

### ⭐⭐⭐⭐⭐ Firm but soft

### ⭐⭐⭐⭐⭐ Fantastic mattress, sleeping like a baby!
*by C***B on 20 August 2026*

Great mattress, a little on the firm side, for me, because of my hips/arthritis. I bought a nice memory foam topper & now I’m sleeping like a baby. Probably the best mattress I’ve ever had. My daughter tried it out and loved it, so much, that she, and her fiancé, added a king size one to their wedding shower registry. ( of course , I HAD TO buy it for them ) The newlyweds, absolutely, love it.
