I weigh 110kg. The mattress deformed in the areas with softer cells. As a result, I was missing the hard cells in my back. I wouldn't recommend it for our weight.
I weigh 60kg and I've taken on a medium firmness, I've had it for 3 years, if I don't turn it regularly I can feel the middle sagging slightly, otherwise I'm satisfied.
im about 71kg. I put a topper on the mattress. i would look online what they recommend. Mattress sellers are all a bit wishi washi with what the recommendations are .The terms arent fixed to any weight recommendations. Else the mattrass is nice
I find the mattress rock hard. Unfortunately, I bought another one. It's better to lie on a test bed, especially if you're a bit heavier. Would never blindly buy one again.
