Sleep Innovations 3 Inch Support Foam Green Tea Mattress Topper review

Sleep Innovations' 3-inch topper is the firm option on this list. It uses responsive support foam that the company says feels more buoyant and uplifting than memory foam, with a medium firm feel meant to keep the back aligned in any position. That makes it a fit for a mattress that has become too soft rather than one that is too hard. The cover is hypoallergenic, machine washable and woven with green tea and cool-touch fibers, and the open-cell foams are designed to release heat. It comes in full, queen and king only. When we checked, a full was $199.99, a queen $219.99 and a king $239.99. Sleep Innovations backs its toppers with a 10-year warranty. Sleepers who want the hug of memory foam should look higher on the list, since this topper is built for support first.
