Beautyrest
Community verdict
The Beautyrest Hybrid Series Four delivers a luxurious, hotel-like feel with strong pressure relief and excellent motion isolation. Buyers praise its body-conforming memory foam paired with sturdy coiled support, which helps reduce back aches and joint pain for many sleepers. However, several owners note that its extreme weight and tall height make finding fitting sheets difficult, while others cite long break-in times and concerns regarding premature sagging.

The hybrid mattress allows for the memory foam to conform to my body, yet is firm enough my back stays perfectly supported.
even if you have a partner , you will not even hear that he is next to you 😅🤣 , because you will not feel any movements
The series 4 is too tall and too heavy. It’s hard to find good sheets that fit it.
I would not recommend it at all. I have had it for a few months now and since it was delivered I have had problems getting comfortable
