Simmons Beautyrest Split Queen 9" Regular Flat Foundation 700810116-5051 (2 Stück bestellen)

The whole process was straightforward once I figured out I needed two, and the split foundation supports our heavy hybrid mattress without any sagging. Assembly took maybe ten minutes total, and the 9-inch height works perfectly with our low-profile frame.

Ordering two was a bit tricky, but the 9-inch height sits perfectly under my hybrid mattress and feels much sturdier than my old wooden frame. The foundation aligns perfectly with the mattress edge, and it’s completely silent when I move around at night.

Swapped out my old box spring without a hitch—this flat foundation sits perfectly under my hybrid mattress and the queen size matches the frame exactly. Took about 20 minutes to set up alone, and it feels solid with zero squeaking.
