HON Perch Stool, Sit to Stand Backless Stool for Office Desk, Black (HVLPERCH)

Works well. One thing to note is you will need something to keep it in place if you are on a tile floor as it will slide if you lean on it. Would have been better if it had a base that had more grip and weighed more.To the person who said the seat failed because of 2 3/4" screws. That is because you installed it wrong. There is actually zero weight on the plastic sleeve. You did not have the metal cylinder in the correct place. This happened to me because the stickers that said to line up here were offset and luckily i tested it out with some force before sitting on it.Before you sit move it in all directions with some force with your hands to make sure the metal cylinder is in place or you will be hitting the floor in no time

Product is well made. Easy to put together. Only thing I did different, instructions say to attach plastic cover in the beginning, I attached with the screws when all complete. You could crack plastic if you do it at the beginning.

I have really gotten used to this stool for my standing desk. Unfortunately the first stool I received started lowering while I sat/leaned on it. The happy part of this review is that they sent me a new one very quickly along with postage paid return shipping label so there was not cost to me for the return and the new one works flawlessly.

When I first got the stool it worked fine. After 5-6 weeks, when i sit or lean on the seat, the hydraulic that regulates the seat height slowly sinks until I'm at the lowest point. For background I'm ~205 pounds.

It works well for my adjustable desk. It takes time to get use to.
