I have it for 3 years in 200x160 and I am very satisfied, it really is so good that it feels like it takes away your fatigue... When I went to the store and lay on it, one side was more inclined because many people were lying on it, so I thought that after years it would sit a little, indeed after 3 years it has sat a little but it's not something tragic, also it's not double-sided. Its height is 33cm as far as I remember

In less than a month from purchasing it, it sank as if someone weighing 200 kilograms was sleeping on it. I weigh 50 kilograms. I wake up in the morning and my whole body hurts. The worst purchase I have ever made.
