Review on 💪 Efficient FRNIAMC Hydraulic Gas Lift Cylinder: Heavy Duty 400LBS Capacity, 22'' Overall Height (8'' Stroke) by Renee Patterson

I bought this topper to convert an ordinary office chair into a high chair to use at my high dining table (estimated countertop height). Once I finally got the original cylinder attached to the chair (in theory it was easier than done) this cylinder was easy to fit. Tuck it in and add some pressure. I did notice that it doesn't have a snug fit at the top where the cylinder connects to the chair, but that doesn't cause any stabilization issues and I really like that it sits slightly backwards. Maybe it actually works as intended, I'm not sure. The height doesn't stay in place. It goes up when I stand up and down when I sit down, which has been the case since I first used it. I also notice that my height decreases when I change my weight a lot or sometimes when I get up and sit down again. Several times a day I increase the altitude again. Recently it got worse after about 2 months of use. It doesn't bother much at the moment, so I'll keep using it.
