Base Simmons Beautyrest Cal King 5.5" Low Profile - 700810116-6070 (Encomendar 2)

Had to order two for my king-size setup, but the 5.5-inch low profile worked perfectly with my hybrid mattress. The foundation feels sturdy and the no-return policy gave me confidence in the build quality before buying.

The low profile is perfect since our bedroom ceiling is a bit low, and the box springs fit the frame without any wobble. Setup was straightforward with two people, and the mattress sits flush with no sagging. Just make sure you know you need two units for a Cal King.

I’ve had mine set up for a few weeks now, and the low-profile design is perfect for keeping my bed at a comfortable height. My hybrid mattress fits snugly and doesn’t shift at all. The support feels solid without any squeaking.
