I have a Flexispot C7...awesome ergonomic office chair, until, the plastic base literally split under my big and tall weight. It was rated to 300lbs, and I'm just a bit over that...but, after 8 mos, it failed. So what was I going to do? I played with getting another office chair, rated to heavier weights, but my C7 is pretty darn confortable, I sit for 8-12 hrs per day as I work from home. Then, I found THIS solution. Inexpensive, and rated to 2500...I figured I'd give it a shot. It arrived in less than a week this morning, and 10 mins of simple assembly and my C7 is now ready to roll again! What a great solution to a problem that many of these "normal sized people" office chairs present. Recommend you get the Lifelong Office Chair Wheels Replacement Rubber Chair Casters for Hardwood Floors and Carpet, Set of 5, Heavy Duty Casters for Chairs to Replace Office Chair Mats - Fits 98%...as well, for hardwood floors.

I had an office chair with a plastic star base. 1 year and 1 day after I bought it, one of the arms broke where the caster attaches. I was worried I'd have to buy a whole new chair, but looked and found this.The hardest part was getting the old star base off the gas cylinder. if you can't get the old one off, look for a video on youtube where they show you how to remove the clip and take the base off the cylinder. Once I did that, I was able to put it on the ground and whack at the base with a rubber mallet and it dropped off. I had literally hit it 50 times with WD-40 sprayed all in there and it didn't budge, but once I took it off, 2 hits on the old base and it was off.The new base went together perfectly. The five arms have two screws each to attach them to the center. This is much sturdier and a little taller than my old base, so that's nice. Totally worth the purchase!

I have very long legs that I sometimes tuck under my chair. This base is curved so well and I don’t run over my toes! It’s also extremely sturdy and can handle someone over 450lbs for sure!

Bought this base to add to an office chair. I believe it’s noted in the description but this base does NOT come with wheels. Not an issue I already had some. The base itself gets loose every couple of months or so and it’s not a huge deal, just need to retighten the screws. You’ll know because the chair will start rattling and then you’ll see the legs are a little wobbly. So far retightening has worked and no issues with stripping. Overall a good product.

I admit I'm a large guy but the damage to my office chair actually came when changing out the casters for a heavier style...I heard a "crack" but couldn't see any damage until about a month later when one leg just gave way. Enter this new chair base. All I can say is, awesome! I purposely ordered a metal base thinking I could bypass any structural problems down the road. I admit, I was a bit taken back when the package arrived and it wasn't a large, flat box like I had expected. I did find it was super easy to assemble however and they even tossed in a cheap hex-key (allen wrench) to do the job. I had the base put together in 5 minutes and slid my chair's hydraulic cylinder into waiting for trouble that never showed up! I did push on it a bit more than necessary simply because the chair sat so much higher than it had on the original base. Trust me...this is a great problem! The other was so low I felt as if I was at a preschool table again. Now...I am a man behind my desk! The unit assembled easily, is quite sturdy and now my chair rolls with ease! What is not to love??

Replaced cracked chair base. Straightforward repair. Stronger than original molded resin base

Have a great char at work that is comfortable and affordable. Problem was the plastic base slowly cracked around the wheel mounts. Assembly of the new metal stand went well. Only critique (which is not a fault, just hindsight) is that its a little taller, so if your height is an issue, also look into a shorter piston base to go with this produce. 10/10.

I received the first box damaged and there are no screws in the box, so I ordered a replacement, the second box came damaged and there are no screws in the box. I’ll be returning the second order to. No quality control whatsoever. The base actually seems solid metal and sturdy but it is worthless without the screws the sides twist and fall off.

Avevo bisogno di sostituire la base della mia serie da ufficio danneggiatasi dopo neanche troppo utilizzo.Mastery Mart si è rivelata un ottimo sostituto, di materiale decisamente più resistente e robusto rispetto alla precedente, sono anche riuscito a recuperare le rotelle della sedia che si adattano perfettamente anche a questa base.Nonostante l'utilizzo intensivo, ritrovandomi a lavorare da remoto, non ho avuto ancora problemi da questa base.

Acheté pour changer le pied de ma chaise de bureau qui commençait à me lâcher (je pèse plus de 130 Kg).Le nouveau pied est à assembler : branches à emboiter sur un anneau central puis à visser avec les vis et la clé tout deux fournies. 5 minutes sont suffisantes pour le montage.Le pied donne une impression de robustesse, debout dessus il ne bouge pas et est très stable au sol. Il s'agit de tubes complet et non de demi tubes comme l'on peut trouver sur les pieds de chaise standard qui lâche au bout d'un moment.A voir son évolution dans le temps mais pour l'instant j'en suis très satisfait.
