Our take on the Beautyrest Cotton 3-in. Thick Soft

The Beautyrest Cotton 3-in. Thick Soft is a medium-firm mattress topper built from cotton filling over a Bonell and pocket spring core. It adds roughly three and a half inches of cushioning to a firm or aging mattress and softens pressure points without the full cost of a new bed. It suits sleepers who want a plusher surface on a hard mattress or a guest bed. Against foam toppers it breathes better and keeps more bounce, but it is heavier, less contouring and harder to move.

Questions and answers

Will this make a firm mattress softer?
Yes. The cotton fill and spring core add about three and a half inches of medium-firm cushioning, which takes the edge off a hard mattress. It will not turn a firm bed into a plush one.
Does it sleep hot?
Cotton breathes better than memory foam, and most owners report it sleeps cooler than foam toppers. A mattress protector and breathable sheets help further.
Can I use it on an adjustable bed?
The spring core is flexible enough for most adjustable bases, but check that the topper stays put when the head or foot section raises. A grip pad underneath helps.
How do I clean it?
The cotton surface is not machine washable. Spot clean and air it out, and use a washable mattress protector over it for regular cleaning.
Does it need a box spring or foundation?
No. It sits directly on your existing mattress. A flat, supportive mattress underneath gives the best result.
Will it fit a king mattress?
It is sized for a king mattress. Measure your mattress before ordering, since some deep mattresses stretch the fit.
