7.5 Inch Twin Metal Box Spring - Sturdy Mattress Support with Wood Slats for Bed Frame | Best Price | Ideal for Guest Rooms, Dorms & Small Spaces

Perfect for what I needed: a sturdy, metal foundation. I have an old fashioned bed frame that doesn't have support beams across the center, only on the edges. As a result I have broken two foundations because the wood was too thin to act as the only support. I guess most wooden foundations assume your bed frame has support across the middle. Well, this frame is all steel wrapped in a fabric cover. The top is a slightly springy steel mesh that is very sturdy. It can easily hold two adults (and a cat), but it's only a foundation so you'll need an actual mattress and bed frame too. Great build quality, no assembly (it folds flat; useful for moving!), and reasonably inexpensive. Exactly what I needed.
