It was super easy to set the bed up using these risers. They perfectly fit the wooden dorm bed. The bed was also stable with them under. I worried when I bought them and they worked better than I would have hoped! Excellent purchaseWe needed the extra space for storage in my son’s very small dorm room. I had seen someone else used these so I bought just in case we needed them. Definitely came in handy, so easy and useful!We used these on my desk to get it closer to the height of our bed since I use it as my nightstand as well. They were easy to use, we had the desk up higher in minutes!!! I can see me buying more to raise other pieces of furniture in the house. ????Excellent! Used these sturdy risers to raise the height of a 48 inch long table to make it a good height for sewing projects! No back pain with last project!the inner size is too small for my son's bed. but would be goodThese bed risers rise my bed effectivelyFit great for square post.What I need was just riser for desk. I bought this one. The set for desk works well. But the left big one for other bigger furniture turns out to be useless to me.Does what it says on the tin, each leg comes in 2 parts to either use the small or large part on its own or they are stackable together to make the largest piece, very good quality, used to lift a laser machine higher to save on my back, works 100%sturdy and well designed. The lid traps the chair foot securely and reliably.A tad overpriced - but very convienent .Excellent product very strong, used to raise my bed up to a point that allows me out of bed easily. The old bed height was slow low it was difficult at my age to get out, now I just swing out my legs and stand up. Same in reverse no longer an excessive drop!Excellent, new Bed was way too low, these have restored comfortategood quality
