The mattress is really comfy nice medium firm mattress, the covering is nice material, we left if for about 4 days to actually open it’s self up properly as after been shrink wrapped it takes time for it to readjust to being open. Very good value for the money and very quick delivery times. I would definitely recommend it to my friends & family, if they asked about it.

Works well on a day bed where mattress thickness for trundle storage would be an issue. Guests report that it is very comfortable.
