Two inch Bragada toppers are good for stomach sleepers and those who want to soften up a fairly comfortable bed. You will still be able to feel some of what is under the pad. Three inch Bragada toppers are a very popular thickness - it is most often recommended for side sleeping because when sleeping on your side you increase the pressure points of your hips, shoulders and other joints. 3 inch toppers absorb this pressure nicely and conforms to the natural curve of your body. Four inch Bragada toppers will completely transform your sleep surface. You will feel mostly the foam and very little of what is underneath. Recommended for side and back sleepers or those who want the feel of a foam bed but without the expense of a foam bed.
