5 x 50mm Double Wheel Office Computer Chair Castors, Coldene Castors

Perhaps I'm too heavy for these casters, but after only a few days' use of them on my office chair (and I don't sit in the chair all day every day, only for about 2 hours a day at most), one of the casters came adrift. I say came adrift because it didn't exactly break, but the wheel is in two halves with a bar in between joining them, and they pop together, and it came unpopped. I popped them back together and sat back on the chair, but the next day either the same one or another one (they are identical) did the same thing, and then the next day it happened again. So I took them off and put the old ones back on. As I said, perhaps I am too heavy for them, but I didn't see anywhere that they have a weight limit. I wouldn't buy them again for the reason given.

We have a couple of old office chairs and when a castor got broken I thought we'd have to chuck out the chair - especially when all DIY shops had nothing like them. So I was surprised to find these on Amazon and still thought they probably wouldn't fit - but they do! And five are cheaper than one from the shops so delighted. They arrived quickly and well packaged so all pristine.

I only needed one castor but these seemed good value. Just as well as another one broke a week later. I still have another three in my desk drawer so this pack was excellent value. The castors are decent quality too.

Having had broken wheel on office chair I decided to replace all 5. They were easy to push on and I can now use my seat again. Lot cheaper than a new chair

Terrible, only needed to replace one wheel on my office chair, but they seemed good value. After about a couple of weeks the replacement wheel broke, I didn't mind to much as I had another 4 spares. I have now gone through all spares and it is always the replacement wheel that breaks. The quality is awful, do not buy!!!!

They did the job, simple to replace just unplug the old ones and push in these. The chair is a lot smoother. Its nice to be able to get hold of them and not throw the chair away.

HAD THEM BEFORE. THEY FIT WELL AND WORK WELL BUT ARE SOMEWHAT WEAK AND PRONE TO BREAKAGE.HOWEVER THEY ARE VERY CHEAP AND SO REPRESENT GOOD VALUE.

It's a castor - not much else to say about it. Still working on a daily basis. Recommended.
