I love how this comfortable mattress pad adds to the comfort of our new bed which is a NEST hybrid with a combination of inner spring at the base and gel infused memory foam at the top. But the feature I like best is the way it keeps our sheets, which are a bit large for this new mattress, from shifting all over the bed and puddling up in certain areas! It has a slightly grippy quality, and I am loving that! The only negative things I could say are: It must be washed in an oversized front loading washer/dryer. Mine is not large enough to handle it. And the elastic sides that you use to "attach" the mattress pad to the mattress seem kind of flimsy, but here's the thing... once this pad is in place, it does not move. The grippy quality really holds it in place more than the elastic sides do, so I don't think the elastic sides really do much of the work.
