We ordered 2 GhostBed All-in-One XL Twin foundations to turn our XL twin mattresses into a split king. The foundations are easy to put together and they look great sitting side by side. So much more simple than having a metal frame and box springs and the legs will not harm the floor like metal frames some times do. We are very satisfied with our purchase.
I really appreciate this foundation. Easy to assemble, very sturdy, doesn't make any noise and looks great. The only thing that I didn't liked was the fact that they advertise as if I want, I could buy an extra set of legs to increase the height. I couldn't find this product on their website.
