Sleep Inc Sleep Cool 14" Medium Hybrid Full Mattress balances responsive support and comfort-forward memory foam with a pocketed coil core to keep nights cool and restorative. A breathable cooling cover and black side panels help dissipate heat while polyurethane layers work with the coil system to deliver targeted pressure relief and reduced motion transfer. Made in the USA and backed by a 10-year warranty, this full mattress pairs easily with standard foundations or a box spring for dependable nightly support.
