This hybrid mattress combines cooling comfort, targeted support, undisturbed sleep, and easy setup to suit different sleep needs. It has a 3D knitted fabric cover paired with cooling memory foam-this combo boosts breathability and wicks away moisture, keeping you cool through the night, while the gel-infused memory foam and independent pocket coil system work together to offer full-body support, align your spine, and relieve pressure.The zoned pocket coils add more practicality: they absorb motion, cut down on noise, and enhance edge stability, so your partner's or pet's movements won't disturb your rest. Plus, the mattress ships compressed in a box-you just unroll it and let it expand for 24 to 72 hours-making delivery and setup hassle-free, and it works well for back, side, and stomach sleepers alike. Size: medium.
