The Leesa Oasis Chill Hybrid is a 13.5-inch premium cooling mattress designed to deliver an optimal balance of pressure-relieving comfort and targeted support. Engineered specifically for hot sleepers, it features an Ultra Cool Cover infused with advanced fibers to maintain an ideal sleep temperature, paired with a layer of copper-infused memory foam that actively draws excess heat away from the body.

Beneath the cradling foam layers, an 8-inch core of individually wrapped, zoned lumbar springs provides concentrated support around the hips while ensuring excellent edge structure and maximum airflow. With its medium-firm, "cushion-firm" feel, the Oasis Chill offers outstanding spinal alignment, making it a perfect haven for back, side, and combination sleepers seeking a cool, restorative night's rest.
