Does this Heavy Duty cylinder only fit into other "Heavy Duty Big &amp; Tall" chairs, or is this made to replace the standard (up to 250 lb) cylinders?

It will fit most chairs quite well. There are some chairs that have bases with smaller or, in some cases, larger holes for the post to sit in. However, in my experience this is a "standard" size diameter. It is worth noting that this cylinder is quite tall. This cylinder is as tall when it is fully compressed as the original cylinder for my chair is at its full length. But, then again, it IS for big AND tall.

Hi, can't say for sure as it sounds like your holes are elongated. Best thing is to maybe order one and see if it fits. I will say, all 4 of our chairs needed new parts and these worked perfect.

I don't know. I got them for my desk chair with arms. The only name I could find on the chair is "True Seating Concepts". I could not find the casters to fit in any local store. After much trial and error, I went on-line, and using the exact measurements of the old stem, found this one that fits perfectly. I bought a set so they would all be new, but saved the three unbroken old ones in case of another breakdown.

Most cylinders are fairly "standard" in diameter. There are a few by some companies that are the exception but, I would say you should be safe in buying this for virually any chair base. If you are not certain you can always measure the hole in the base of your chair and check it against the specs for the cylinder,

My research to find replacement casters found that most chair brands utilize standard size casters.

Yes it should fit, but you might have to drill new holes if they don't line up. I have purchased 3 of these swivels for 3 very different chairs. One lined up perfectly, one needed 4 new holes drilled, and one needed a piece of steel to addsupport and for 2 new holes. I bought the steel at Home Depot for eight dollars. All the chairs/ swivels work great.

Glenn,I wouldn't know about this brand however, most chairs with these types of cylinders have the same dimensions where they interface with the chair. I would measure your chair or contact Serta.John

sure... it actually comes with pads for custom fit to different thickness legs. Also, it has a removable insert so it will even fit a lawn chair. In short, yes it will fit any chair out there. AND I use mine lots. Actually, I have the one that came with my zero G, and this one. Table on both sides now.

I cant say for certain if it will or it wont. I searched a couple of web sites before ordering mine and they stated that about 90% of the chairs on the market can use the same basic parts. Mine was sold to me with a good return policy so I ordered a set of casters and a new piston and hoped for the best. They both fit perfectly and were easy to install. YouTube has good vids on piston replacement. Repair parts are a lot cheaper than a new chair. Good luck!

Hi, I just responded, but I think I am wrong. There is a heavy duty cylinder with a 1.1" shaft that is closer to the 28mm of your cylinder. Hope this helps.

Original was probably 3/16th inch. I couldn't find that size so I read where 1/4 inch had been used by some that repaired there gravity chairs. It was a little tight but I believe it is much stronger. Time will tell.

Not sure if it is an EXACT replacement for a D400p, BUT this part worked perfectly on my "odd make" chair I bought at Staples! Key work in the part name is "UNIVERSAL" and it appears to be exactly the same as other chairs I have had problems with. Amazon offers an EXCELLENT replacement policy if it is the wrong part! Go for it! MY replacement part works JUST GREAT! RGGale

I am 6'9" and 330 lbs. I bought this chair 2 years ago and loved it until the gas cylinder failed, converting this into a low-rider. I tried to replace the cylinder myself using a "universal" cylinder; that failed; so I bought this chair a second time. The gas cylinder has again failed after one year. I love the chair, just wish I could find it with a non-adjustable post in lieu of the gas cylinder as I have no need to lower the chair. Really comfortable, though...

It may fit in if diameter is same, but won't stay if chair is picked up, due to the lack of a cut out for the snap ring to engage, as "bbubba" points out.

this cylinder is advertised as universal fit. I purchased it for my chair, and have been very satisfied with it.

Hi Robert, I hate to use the word "standard" for director chairs. If you need exact canvas measurements call the company. I am very pleased with my replacement canvas. Follow directions when applying the seat canvas and load the dowels and canvas from the rear forward. New dowels may not be as strong as your originals, but they work. Know if you need square or round dowels. Hope this helps.

I used the 80mm on a standard cheap office depot chair (they're all pretty much the same under $150) and it was a bit shorter than the old one, but otherwise it worked fine. I'm not sure where the measurement would be taken, but hopefully my purely anecdotal advice can help.
