I thought the foundation well designed out and easy to assemble. The foundation is best used with a low, low, low profile twin bed frame (4" or lower). When combined with a mattress on a taller bed frame, the bed was taller than comfortable or appropriate. I bought two of these with one fitting nicely with a low profile frame and headboard. The second foundation when paired with a nice Wayfair taller frame was so high that I had to abandonee the second foundation which cannot be returned after assembly.
