Super comfortable thick mattress. Double fitted sheet fits it perfectly. It does fold to pack away but is obviously quite bulky to store (although it could never fold away flat with the thickness of the mattress!). Having said that, I'm still able to store it upright inside a fitted wardrobe. Very good purchase & is so much better than a camp bed when people stay.. Deborah. Sutton Coldfield, GB.
