Will this make my mattress feel softer?

Yes. The 3-inch TEMPUR layer adds a soft, plush feel and pressure relief, which is the main reason owners buy it. It is best for firm mattresses; on an already soft bed it may feel too soft.

The cover is a breathable, moisture-wicking knit and the foam is TEMPUR's cooling version, but memory foam still runs warmer than latex for some sleepers. Hot sleepers report mixed results.

Will it stay in place?

It has Staytight corner straps that anchor it to the mattress. Owners generally report it stays put, though it can shift if the mattress is very smooth or the fit is loose.

Can I wash the cover?

Yes. The cover zips off and is machine washable. Wash it separately and follow the care label, and expect to wrestle the foam back into the cover afterward.

How thick is it, and does it change the mattress height?

It is 3 inches thick, so it raises the sleep surface by about that much. Check that your sheets still fit over the added height.

Is it good for side sleepers?

Side and combination sleepers tend to like it most because the soft foam cushions shoulders and hips. Stomach sleepers often find it too soft.
