I bought 2 sets of the Lift Your Table Risers Extenders and they are absolutely awesome. They are very sturdy and should hold up very well. I looked a other Risers and didn't like the ones that were only about 2 inches deep to hold the table legs because I was worried the table would fall over if bumped or moved. The Risers go on up the the curve of the table leg (about 6 - 8 inches). I even moved the table around with the Risers on and the table just glided on the carpet with no hint of tipping over. I even lifted the table and the Risers stayed on until I took them off myself. They were packed so well, that I can put the Risers back in the boxes all nice and neat. Shipping was immediate, I received them in less than a week. I am definitely recommending these Risers. They are worth the price. I needed to raise my folding tables for doing crafts/sewing projects and leaning over a regular table height was really killing my back. I would try to do some of these projects on my kitchen island which was great for the height except I had to put everything away to use the island for other things... like cooking (lol). My kitchen island isn't very large, so big projects had to be rolled/folded to work on them and that can be very frustrating. With 2 six-ft folding tables side-by-side, I have an enormous work area (6ft long x 5ft wide). I also have the choice of using one or two tables depending on the project size. Now I can start a project, take a break, and it's still there to continue working on it later.
