The Beautyrest Black® Mattress Foundation is a solid steel, non-flexing base engineered to match and support your Beautyrest Black® mattress. Choose the 9" standard profile for a traditional bed height, or the 5.5" low profile for a lower, more modern look and easier moves through tight stairways. Both heights are backed by Beautyrest's 10-Year Limited Warranty.
The Foundation Built for a Black® Mattress
A Beautyrest Black® mattress is engineered around individually wrapped coils that move independently. That only works if what's underneath stays perfectly still — which is exactly what this foundation does. Solid steel struts create a rigid, non-flexing platform, so the coils do the responding and the base does the supporting.
The quilted border fabric is finished to match the look of your Beautyrest Black® mattress, so the set reads as one piece rather than a mattress sitting on a mismatched box.
Choose Your Height
Standard Profile
9" High Profile
The traditional choice. Adds height to the bed for a classic, substantial look and an easier sit-down and stand-up. Pick this if you're replacing a standard box spring and want the bed to sit at the same height as before.
Low Profile
5.5" Low Profile
Same support, 3.5" less height. Pick this if you have a thick mattress, a tall bed frame or a low headboard and don't want the bed towering — or if a narrow stairway or tight doorway makes a full-height foundation hard to get into the room.
Why You'll Love It
- Solid steel construction — steel struts promote support and durability, with no flex to work against your coils
- Two heights — 9" standard or 5.5" low profile, same price at every size
- Matched finish — quilted border fabric designed to coordinate with your Beautyrest Black® mattress
- Steel grid sleeping deck — the mattress rests on a steel grid and reinforced cover, not directly on slats
- Not manufactured with fiberglass
- 10-Year Limited Warranty

Compatibility
What It Sits On
This foundation needs a supporting frame underneath — a standard metal bed frame, a platform frame or a traditional base. Queen and larger sizes should be used with a frame that includes center support running to the floor.
It is a flat, stationary foundation. If you want head and foot articulation, choose a Beautyrest® adjustable base instead — a foundation and an adjustable base do the same job of supporting the mattress, so you only need one.
Delivery
Choosing a Delivery Option
- Free Thru Door Delivery — included when the foundation is purchased with a mattress. Brought through your front door.
- Thru Door Delivery — the same service when the foundation is purchased on its own.
- White Glove Delivery — carried to the room of your choice and set up in place.
Made to Last
Backed by a 10-Year Limited Warranty
Your Beautyrest® foundation comes with a 10-Year Limited Warranty, and is not manufactured with fiberglass. Using a matching foundation is also the simplest way to keep your mattress properly supported over its life — a sagging or flexing base is one of the most common causes of premature mattress wear.
