Product Description

Give your Tempur-Pedic® mattress the solid support it deserves with the TEMPUR-Flat® Foundation. Engineered to replace a traditional box spring, this durable platform creates a perfectly flat, stable surface to protect the shape, comfort, and lifespan of your mattress. Unlike standard foundations that can flex or sag over time, the TEMPUR-Flat® delivers consistent, long-term support for optimal spinal alignment and deeper, more restorative sleep.

Available in two height options, the 9" High Foundation matches the look of a traditional box spring, while the 5" Low Foundation is ideal for modern beds and tight stairways. Upholstered in a sleek gray fabric, it blends seamlessly with your bedroom décor. For anyone looking to maximize mattress performance and comfort, the TEMPUR-Flat® Foundation is the perfect pairing—strong, stylish, and built to last.

Why It Works

Built to Prevent Sagging, Not Just Hold Weight

A solid, flat platform is engineered specifically to prevent mattress sagging and preserve the pressure-relief performance above it.

A Low-Profile Option for Tight Spaces

The 5-inch low profile is built to fit through narrow halls, stairways, or tight spaces a standard foundation can't.

Designed to Match, Not Just Support

Upholstered in stylish gray fabric, it's built to match Tempur-Pedic aesthetics, not just function as a hidden base.

In their own words

Two delivery professionals unloading a wrapped mattress from a white van outside a home.

Choose white glove delivery and our trained professionals bring your solution inside, assemble, position exactly where you want it, and make sure it’s ready to use.

No hauling. No guesswork. No leftover cardboard.

Ideal for larger items like massage chairs, adjustable mattress sets, and zero gravity recliners. Because the only thing you should have to do is sit down and feel the difference.
