Tempur-Flat™ High Profile Foundation

The flat, non-flexing base your Tempur-Pedic was built to sit on

A box spring is built to flex. Your Tempur-Pedic mattress is built so it never should. That mismatch is why a great bed can start to feel tired early: the base sags in the middle, the comfort layers follow, and the support you paid for quietly goes soft. The Tempur-Flat™ High Profile Foundation fixes the root cause. It is a rigid, flat platform that holds your mattress dead level from edge to edge, at the taller, traditional bed height most people picture when they think "a real bed."

What a flat foundation actually does for the bed on top of it

• Even, full-surface support. No slats to feel through the mattress, no soft spot in the center. The whole sleep surface stays the same firmness whether you lie in the middle or roll to the side, so the materials work the way the engineers intended.
• It protects your investment. A solid base keeps the foam and coils from fighting a sagging deck, which is what most foundation-related warranty claims trace back to. Tempur-Pedic and most premium brands require a flat, rigid foundation for exactly this reason.
• Classic High Profile height. This is the taller of the Tempur-Flat options. It lifts the mattress to a standard bed height that is easy to sit on the edge of, easy to get into, and right where a standard headboard expects the top of the bed.
• Built for Tempur-Pedic, friendly to the rest. Designed to pair with Tempur-Pedic mattresses, and a correct match for any bed that calls for a flat, solid foundation instead of a flexing box spring.

How to know if High Profile is the right one

The math is simple: foundation height plus mattress height equals your finished bed height. High Profile is the tall pick, best under a standard-height mattress (roughly 10 to 12 inches) when you want that classic, sit-on-the-edge bed. If your mattress is already tall, a high-profile base can push the top of the bed up near hip height, which is a chore to climb into, and a lower base is the better call. Tell a showroom your exact mattress model and the team will run that math with you before anything ships.

This is a base, not a bed frame

The foundation carries the mattress; it still needs something to carry it. It sits on a metal bed frame or a platform bed. If you do not already have one, add a bed frame in the same order and it arrives ready to set up. Want the head and foot to raise instead? Compare the adjustable bases, which replace a flat foundation entirely.
