BLTPress Chair Base Replacement, 28 Inch Office Swivel Chair Base, 330 LBS Weight Capacity, Height Adjustable Complete Under Seat Kit

May have to drill some holes as I did for the mounting bracket, but it works amazingly well on a 50+ year old office chair.

Good quality use everyday

fits exactly onto the bottom of my chairs where the old ones where. very nice

Ok. So this has “mobility”. We attached this to an existing seat. It’s from the blue train on the Superman (ROS) at SFNE. Measurement for THAT specific seat didn’t match up but my husband was able to attach it to the seating (which is very measuring specific). It worked fine and does what it spec says on the description. Make sure your measurements match. Good fit. Everyone in the rollercoaster community is impressed.

Wotks as expected. Easy to install.

Purchased this base replacement Aug 2022, and then upgraded the wheels. Everything was good up until this morning when i rolled back from my desk the the leg broke. I'm only 200lbs and this base is rated for weight up to 330lbs and I'm the only one that uses this chair. So disappointed.

Replaced the bottom on an old office chair I've had a long time and is special to me. The replacement was exactly the same despite the chair being over 20 years old. It is perfect !!

Bottom half of office chair, welding cracked. Looked on line for replacement part. Ordered one that looked closely to the damaged part. But holes did not line up to the holes under seat. But used wood screws to bolt under seat and it worked. Thank you
