Sturdy, easy to put together. Wish the one with the wireless remote wasn’t back ordered for a year! Cord on the remote should be longer.
If you try to use all 4, or even 2, “corner pieces” they will pop off (we bought a 10 inch mattress, maybe they’d stay on if you have a thinner mattress). We just have one in and I just slide the top of the mattress over a couple inches everyday, no biggie, but they should have taller ones for thicker mattresses or say you need a thinner mattress
