Very comfortable and supportive. This is the second mattress we bought. The first was for our guest bedroom for our house in Naples. My 91year-old mother-in-law enjoyed sleeping on it so much we bought her one for her own house.
This one took a little longer to fully stretch out, but after 2 days if was perfect.
I was really excited to get this mattress after reading all of the reviews on the website. However, the bed is very firm. Normally sleep on my side and when I do that on this bed my hip hurts. I was given a mattress topper to help ease this but the topper doesn't seem to be very quality.
