Add a plush, supportive layer of memory foam to your existing mattress with the BROOKSIDE 2.5 Inch Gel Infused Memory Foam Mattress Topper. Designed to contour to your curves, this topper supports your lower back keeping your spine neutral. Settle into your most comfortable sleep position without the pain from pressure points. And if you sleep with a partner, the material absorbs motion and isolates it rather than transferring it. That means you will not feel a thing when your partner rolls out of bed. We embrace our CertiPUR-US certification. No harmful chemicals were used in manufacturing this memory foam. Backed by a 3-year U.S. warranty.
