Quilt Layers
  • Cooling Cover: Crafted from a Tencel™ and cooling yarn blend, this cover is soft, breathable, and designed to wick away moisture while maintaining a cool-to-the-touch surface.

Comfort Layers

  • High Density Medium Foam: Provides transitional support and reinforces overall comfort.
Support System
  • 948 Pocketed Coils: Individually wrapped, tempered steel coils (13.5 gauge) deliver responsive, durable support.

  • Foam Encased Edge: Reinforces the perimeter for better edge support and usable sleep surface.
  • 2″ Base Foam: Adds stability and long-lasting structure to the mattress.
Technology That Elevates Sleep
  • QUBE Technology: The upgraded 8lb gel-shell QUBEs independently adjust to your body, reducing motion transfer and minimizing tossing and turning.
  • Graphite Infused Talalay: Enhances breathability and durability while helping dissipate heat more efficiently.
  • Kikoo Thermo-Regulation: Graphite-infused bands have been tested to reduce surface temperature by up to 35%, helping you stay cooler and sleep deeper.

We understand that a mattress purchase is an important investment for you, which is why we offer a one-time mattress exchange within 365 nights of the original purchase. It is important that you sleep on your new mattress for a minimum of 30 nights. Your body needs time to adjust to your new mattress support system. In the event that you do not love your mattress, we work closely with you on re-selecting a different mattress of equal or greater value. The Comfort Guarantee handling fee is $299.95 within our local delivery zone. Exchanges outside of our local delivery zone will be subject to current delivery rates. Our delivery team will inspect all exchanges prior to removal. It is required that your mattress must be sanitary, in like-new condition, and the law tag must be attached to each item. Mattresses that do not meet these requirements are not eligible for exchange. All mattresses are handcrafted and have up to a 1” dimension tolerance.

Our 365 Night Comfort Guarantee provides a one-time exchange privilege and applies only to the mattress. Please reach out via our Contact page to initiate a mattress comfort exchange.

ALL SALES ARE FINAL on power bases, accessories, furniture, frames, custom orders, and exchanged mattresses.
In compliance with strict national and state bedding laws, and as detailed in the manufacturer’s warranty, BedMart is unable to warranty or exchange a mattress that is stained or unsanitary.
