Such high quality padded fabric and solid metal. It has great remotes and 2 USB ports on each side. This is really nice. Raises both head and knees. Remotes have a flash light, memory function and flat button. Very easy to put together. Used two 10 inch memory foam mattresses.
I bought 2 twin XL's to make a split king, so they can go up and down independently, but you can also pair the two sides to go up and down together.
Highly recommended and really great quality. Just beware that the packages are really heavy. 
Still not sure which bed frames could fit around this though - ended up just getting a headboard instead.
