High-tech comfort, redefined! The mattress from the Loop Nano collection represents the new generation of smart comfort in a box. Designed to deliver firm, stable, and healthy sleep, it combines innovation, support, and freshness in perfect harmony.

Beneath its ultra-soft quilted cover lies 2″ of copper-infused anti-microbial gel, which helps regulate temperature and keeps the surface clean and cool night after night. Next, 1″ of responsive nano pocket coils adjusts to every body movement, providing targeted support and reducing motion transfer. Then, a layer of bio soy transition foam and high-density bio soy foam adds durability, comfort, and stability. Finally, 8″ of ultra high-density base foam delivers solid, consistent support for restorative sleep and long-lasting performance.

With its firm feel and generous 13.5″ profile, the Loop Nano offers balanced comfort that’s perfectly compatible with electric adjustable beds.

And since it comes in a box, setup takes just a few minutes!

You can rest easy knowing that a portion of every purchase goes to the Quebec Breast Cancer Foundation—the reason behind that bright magenta touch.

RD Furniture also offers several king 78″ mattresses designed for pure comfort—ideal for those who love extra space without crossing over to the other side.
