Well made, very sturdy. We have split king adjustable base we found the the fit was snug and as previously stated in an review, were concerned about the adjustable base rubbing against the side railings and the potential fraying of the fabric and wear on the motor. So, we removed the inside plastic bar on the two sides pieces since you do not need that or the wood slates if you have the adjustable base. It worked, and the bed moves much smoother now inside the frame. Best to remove these side pieces before you put the bed together so you can lay bed sides flat on floor and use an electric screwdriver if you have one, the screws are extremely long and there are 7 per side, time consuming and tiring if using regular screwdriver. Definitely recommend two people for assembly. There is a you tube video of someone putting together the Puffy frame, worth watching since the included instructions are pictures only. Highly recommend this bed frame, We love it!
