This is the second time I've bought a mattress topper, the first one was for our motorhome that only had a thin mattress, the bed I have at home is OK but since having my hip replacement, I found the bed uncomfortable then realised I always have a good night's sleep while away. I ordered it on Sunday and it was delivered Tuesday morning at 8am giving the topper time to expand. Also I love the cover supplied with it and could really do with a spare for when it needs washing. Love, love love it
