They worked excellent for the 1st couple weeks, then 1 wheel started to make a squeaking noise, which makes it feel like a wheel is dragging now. Thankfully they were cheap. 1st couple weeks, my chair never rolled so quiet and smoothly.

Lets start off by saying I'm a big guy. I weigh 400lb and I've had some good luck with office/computer chairs and I've had some bad luck.

I am currently sitting in a LayZBoy branded big and tall chair. I've had it well over a year and never really had a complaint other than the arm bolts loosening which I fixed with epoxy. Well just a few days ago I noticed my chair was tilting when I was trying to move around in it. Upon further inspection I needed a new wheel; and now we're talking about these bad boys.

These wheels feel very sturdy in hand, they look very sleek. Installing them was a breeze, I've tried other wheels in the past that didn't quite fit like expected but that was not a problem with these. The next thing I noticed after installing them is how MUCH easier my chair moves on my carpet now. My apartment has a standard low cut carpet and the old wheels would give me some resistance every now and then trying to scoot. As of the writing of this I can't think of a single negative thing to say of these caster wheels.

If any of this changes in the future I will return to edit this review, hopefully that will not be needed.

Tl;dr: These caster wheels are amazing, on carpet they roll like a dream and have a very nice fit and finish.

good wheels I made the mistake of buying wrong wheels first time BUT ill explain why on both

For the record I recommend buying these excellent wheels --just avoid the other ones

1. these black wheels are roughly 95% the same height as the standard office chair wheels that come with most chairs theses are the 2 inch wheels and there what you want to buy avoid the 3 inch wheels

2. there made a lot better and are mostly metal where as standard wheels are mostly plastic well built and solid

3. they roll and glide easily and fit in easy and for the 20.00 paid and excellent value
4. also while they aren't as wide as the other wheels they will do less damage to you floors or carpets

Now the problems with he other roller blade wheels I bought

for the record the company's customer service was great --OFFICE OWL -- chair wheels there 100% satisfaction guarantee was perfect they gave me a full refund after just providing a bit of info and the reasons why I was returning it

1. I bought 3 inch wheels so the listing said but they where a bit taller then that about 1..1/4 taller
2. the wheels where so drastically taller that 2 times my chair tipped over I fell forwards didn't get hurt but still wasn't nice
3. also due to fact that the wheels where very narrow that's probably another reason they tipped over where as normal standard wheels about probably 3 inches wider then theses
4. the height of them was so much different I could no longer get my desk keyboard slid out all the way anymore because they would bump in to my arms rests
5. also I noticed poor leg circulation due to the difference of height and moderate to increasing lower back pain due to these so unless your tall and have long legs make sure you always measure the height of your chair and wheels first before buying new wheels
6. the only good thing about these was they did work well and they glided across floor very well

I bought to replace wheels on chairs that are, at least, 30 years old.
The chairs has the plastic double wheels on them. My husband is 6'1" and 270 and, well, one of the wheels finally gave out. Not to mention that they didn't roll the best anymore. Now he can sit in the chairs without worrying about the wheels, thanks to the weight rating.
These chairs now ZOOM across the floor. It was like putting roller blade wheels on the chair. You have to sit down with purpose or your moving to the other side of the room.
We love them! The cat, not so much. She loved jumping in the chair when she was playing. Now that they move so well, she's stopped doing the run and jump into the chairs.
The chairs are also a lot quieter now. They are on an upper floor and, if someone was downstairs, the noise of the chairs moving would drown the tv out. Not anymore.

I highly recommend these as replacement wheels.

Careful when you push off for the first time. You'll be sailing across the office wondering why you didn't know about these sooner. A real pleasure.
