We've had this since late September '22 & are really upset with it. After just a few weeks it went from really good to lumpy & uncomfortable. There is a trench now on both sides of the mattress (my partner & I weigh 190 lbs each) and the centre is significally higher and harder than the edges. The fabric is also piling and discoloured. Please see pictures and maybe shop for a better mattress than this one.
