  • Seems sturdy, easy to assemble
Color: Gold
The plastic leg base thingy on my office chair cracked and the hydraulic column thing went through and was dragging on the floor. I needed either a new chair or a new base. This was $75, spendy, but cheaper than a whole new chair. I like the gold color, it was easy to assemble, took about five minutes. You just attach the legs to the central assembly and screw them in. I wish there was some kind of instruction on how to remove the old hydraulic thing from the chair, but YouTube helped with that. The wheels roll well enough. Hopefully it’s sturdy enough for my chonky booty, but it says heavy duty. The shiny gold is very fancy. Oh, it raises up taller now, which is great, as I always wished my chair went up just an inch higher. So if you need a replacement base for a beloved office chair, this one does the job, and it’s shiny. ... show more

  • Good replacement for a 4-Spoke unit
Color: Silver
I purchased the replacement base to use on a old desk chair which had only four legs(not legal today). The assembling of the base was straight forward. After putting the chair onto the base the overall height was too high. This was partially due to having to add an adapter plate on the chair in order to bolt on the tilt mechanism. The most effective change to lower the height was to replace the wheels with a smaller diameter set. I could have purchased a different chair base but this one is made with steel where the others were plastic. This unit is much sturdier. ... show more

  • New base saved the day! Worth the money.
Color: Gold
My velvet task chair from Wayfair broke 2 years in, and wasn't under warranty. I was reluctant to get rid of it, because I love the color and feel of the seat. After SEVERAL attempts at fixing, this base replacement was my last hail Mary before throwing out the chair. I bought a base plate and this base set, and the two together worked perfectly to restore my chair to her former glory. It feels more stable now too. Big fan of the gold, this is a very high quality base. ... show more

  • Wish more product details upfront
Color: Silver
A great replacement choice. Only problem is that it doesn't highlight uo front that this kit includes the longest (of four) choices of lift cylinders. I was misled as the description says 'universal' fitting. Only to find out later that there are actually four sizes of lift cylinders available on their website - all are called 'universal' LOL. Unlucky for me, my existing lift cylinder was the shortest. So instead of returning the whole package back to faithful Amazon, I just otdrtrd the extra cylinder that I needed, since I like the overall product anyway. So future buyers, check your size of cylinder first!. That's my advice! ... show more

  • Great fit
Color: Black
Easy to install on an old but loved office chair. Made the chair feel like new. The wheels on this are great. Much better quality than the original wheels and looks like they will last a long time!

  • Works great!
Color: Gold
I bought this to put on the wide office chair that you can sit criss-cross in. It didn’t originally have any wheels on it. This fits perfectly. The wheels roll smoothly! Love the gold color option!
