Office Chair Lifting Rod Fixing Pipe Clamp Connect the clamp to the large office chair cylinder piston to prevent the seat from sinking, with a variety of matching sizes and heights【Upgrade】

easy to install and very durable. super easy to fit on the shaft and pretty adjustable by mixing up which ones you want to use. They work great for keeping the chanir stem from sinking lower and lower.

Works great. Cheaper and easier than replacing the cylinder. Just as advertised.

I guess it’s my fault for not reading all of the product details, but I was disappointed to see that these clamps were 3D printed clamps and not made from a solid piece of product. I will say that’s they did clamp on the piston easily and have worked so far.

What a pleasant surprise what a great way to fix your chair. It took about five minutes if not, and the chairs as good as new.

The Hydraulic system in my office chair failed and to replace it, I would have to pay for a new system and installment. I searched for an alternative fix and found ARSUNOVO Office Chair Lifting Rod Fixing Pipe Clamps. It took me less than 3 minutes to clamp these onto my chair and I don't have to take time out to keeping raising my chair repeatedly. I received 4 clamps of various widths. I used three for the height I wanted. If I want to change the height, I can just remove one or more clamps and I don't have to worry about replacing the hydraulic system. Works great, well made and for the price saved me a lot of time, money, and frustration. The Clamps are black which matched the black base of my chair making them not even noticeable.

As described but after short useage one of the rings broke in half. Still able to use the remaining without any problems.

GREAT VALUE - DO WHAT THEY SAY THEY DO AND THEY WORK. I SAVE A LOT OF MONEY BECAUSE FOR YEARS WHEN THE TUBE UNDER THE CHAIR NO LONGER STAYS UP AND IT DRIVES ME CRAZY GOING DOWN ON ITS OWN, I WOULD THROW AWAY THE CHAIR. THIS LAST CHAIR I ONLY GOT A FEW MONTHS AGO AND ALREADY IT WAS SINKING SLOWING ON ITS OWN WHERE MY LEGS FELT LIKE SPIDER LEGS TO A KID CHAIR. I DID NOT WANT TO HAVE TO BUY A NEW CHAIR AND I RESEARCH TO SEE IF THERE WAS A WAY TO FIX IT ON YOU TUBE. ALL OPTIONS SEEMED COMPLICATED BUT I WAS WILLING TO TRY. UNTIL THIS POPPED UP ON MY COMPUTER SEARCH. I TOOK A LEAP OF FAITH AND LO AND BEHOLD, I USED 3 OF THEM AND MY CHAIR HAS NOT GONE DOWN. LOVE LOVE LOVE AND WOULD BUY THIS PRODUCT AGAIN.

Very helpful

These are perfect for my sinking chair. Arrived much sooner than anticipated, and so easy to put on to my office chair which had started to sink a centimetre or so every 15 minutes, until I put it back up again. I've added these, and now the chair can't sink. They work really well, and don't notice them at all. So easy to install. Very happy with these (much cheaper than a new chair!!)

el producto es bueno, pero en un movimiento se abrió, lo solucioné con un cincho de plastico y listo

C'est parfait, c'est moins cher qu'aller acheter une autre chaise et c'est super solide

Broke after 1-day Hollow Brittle Plastic
