We picked up this base to replace the base on a gamers chair, and it has been used daily for the past couple of months without issue. Easy to install - my 14 year old installed it himself. Good quality and appears durable so far (with a 14 year olds rough daily use).
I PURCHASE THIS ITEM BECAUSE THE ORIGINAL BASE TO MY OFFICE CHAIR STOP WORKING, I HAVE TO SAY, THE ITEM ARRIVED IN GOOD TIME FROM ORDERING, AND THIS BASE OPERATES BETTER THAN THE ORIGINAL EVER DID, A GOOD BUY, VERY HAPPY,
Perfect for what I needed. My old chair legs were Cheap plastic, that broke twice in a month. These legs are VERY sturdy, and the casters are very nice as well.
All metal base, the hydraulic cylinder seems solid, the plate for attaching to the chair seems pretty good. The casters are crap though, plasticky and flimsy feeling. Good thing I had better ones laying around to use.
