Mattress topper

Yes, I recommend this

Bought for a guest bed. It came packed tightly in vacuum bag and took several days to fully fluff up after shaking and plumping. Feels quite substantial and should make improve the comfort level of the bed. Not tried yet.

Silentnight Airmax Matteress topper

Originally posted on Silentnight

I bought this a month ago and have been very happy with it. It is thick and cosy. The one problem is that it stores too much heat from our electric blanket so we have to remember not to leave the electric blanket on to get too hot, and then its fine.
