The UniPon Medium Firm Queen Size Mattress is a 14-inch hybrid design that pairs comfort foam layers with individually wrapped 2.0mm reinforced steel coils. It is built for side sleepers who need pressure relief in the shoulders and hips while maintaining proper spinal alignment, and the zoned lumbar support adds extra stability where it matters most.

This mattress is designed to sleep cool. The breathable knit cover, cooling gel-infused foam, and airflow-promoting pocket coils help dissipate heat and moisture, making it a good choice for warm sleepers.
