A majority of orders — more than 90 percent — are fulfilled by U.S. facilities, aligning with expectations for prompt delivery and dependable production.

Comfort and Support

The medium-firm feel straddles softness and support, making it a versatile choice for kids and small bedrooms. It aims to balance contouring comfort with enough support to prevent sinking in for most sleep positions and body types.

• Medium-firm level around 6–7 on a firmness scale
• Contouring memory foam that maintains a stable support profile

Cooling, Safety and Materials

Gel infused into the foam helps dissipate heat, aiding a cooler night while preserving body-conforming comfort. The foam is CertiPUR-US certified, reflecting adherence to safety and emission standards. The inner cover uses a fiberglass-free rib fabric blend to provide a safe, effective flame-retardant layer without fiberglass concerns.

• Cooling gel reduces heat buildup during sleep
• CertiPUR-US certified foam supports lower emissions
• Fiberglass-free flame retardant inner cover for safer, irritation-free nights
