The SealyChill Gel Memory Foam Pillow combines a medium-firm polyurethane foam chassis with a top-layer gel lamination. This design is intended to provide cervical support by maintaining a high rebound delay, which helps keep the head and neck aligned during sleep. The cover is made from a polyester and spandex blend, which is chosen for its ability to facilitate heat transfer between the user and the gel interface.
Specifications show the foam is rated for durability, with tests indicating it retains the majority of its height over several years of use. The gel layer is verified to lower the surface temperature upon contact, providing a "chill" effect that is most noticeable during the first few hours of rest. Because it is a solid-molded pillow with a 5.5-inch profile, it provides a stable and consistent height that does not require manual adjustment.
Practical steps for new owners include a 48-hour off-gassing period in a well-ventilated room to ensure the foam is fresh for use. Because the gel acts as a passive cooling system, it will eventually reach body temperature; using a breathable pillowcase will help the material dissipate that heat more efficiently when not in direct contact.
- High-density foam provides firm support for neck and shoulder alignment.
- Gel lamination offers immediate surface cooling upon contact.
- Spandex-blend cover is designed for maximum thermal conductivity.
For sleepers who find solid foam too high or non-adjustable, the Supa Modern 2-Pack features shredded foam that can be added or removed to reach a preferred height.
