Bruce Black Patterned Fabric Drafting Chair with Adjustable Arms (Cylinders: 22.5''-27''H or 26''-30.5''H)

A no frills chair that works well. A decent value for the money once assembled properly. I bought two chairs for their high seat elevations to create standing desks in my home (supposed to be healthier than sitting all the time). I intend to alternate between sitting and standing using 50:50 ratio.I too was concerned about the wobble when assembling the chairs. I figured out that the wobble was caused by the center pipe not fitting securely in the hole on the castor wheel base and the top pipe then not fitting securely into the bottom center pipe. The solution was to use a rubber mallet and lightly pound the center pipe into the base, then lightly pound the top center pipe into the bottom center pipe (don't forget the foot ring in between). Problem solved... the chairs then became plenty sturdy. You could also use a block of wood over the pipe and lightly pound it with a steel hammer if no mallet is available. Note, once you pound the center pipes together, you aren't going to get them apart... so make sure you put together right :- )As the assembly schematic was unclear (which was very annoying), the bottom center pipe is the long one and the top center pipe is the short one. This arrangement allows for proper foot ring height. If you are taller than 6 feet, then perhaps putting the smaller pipe on the bottom might work better to accommodate longer legs.After assembling the chairs using the two center pipes, the top of the seat height was 31 inches above the floor at its lowest setting with actual sitting height about 30 inches above the floor due to seat cushion compression. Adjusting the elevation lever to the highest setting, the top of the seat was about 35.5 inches with a sitting height of 34.5 inches due to cushion compression. The seat can be set to a lower elevation if you leave out the shorter top center pipe, which will lower the compressed seat height by 6 inches to 24 inches at the low setting to 28.5 at the high setting.The seat and backrest cushions are comfortable. However, to change the backrest cushion angle to suit your back, you will need to lean back hard on the seat with your back to bend the backrest bar backwards, otherwise, the rear cushion sat a little too upright for my taste. That said, sitting back hard to create a slight bend in the backrest bar was no problem; and after adjusting the angle, the backrest solidly stays in place.What I like about these chairs:(1) They're attractive and are adequately sturdy.(2) The wide range of seat heights (can accommodate a standing desk in my situation).(3) The seats and backrests are comfortable.(4) The armrest has durable rubber like material over a cushion to protect the elbows... i.e., they're comfortable.(5) The armrest are easily adjusted up and down through a decent range... the armrest elevation mechanism seems plenty sturdy.(6) The armrests can be bolted in at either a narrow or wide distance from each other depending on body girth. I chose the narrowest range as being most comfortable (I weight 175 pounds).What I don't like:(1) The directions were absolutely dismal. It took me maybe two hours to put the first chair together after sorting through whether the center base pipe should be the long one or the short one. After an hour of measuring and analysis, I found what worked right for me (as described above). That said and after knowing how to assemble the chair, the second chair went together in less than 20 minutes including unpacking and cleanup.(2) The foot ring has a little wobble, but no big deal... it's sturdy none-the-less allowing you to stand on it to get on and off the chair if you so desire. I'm going to shim it in the future to eliminate the wobble.All said and done, when properly assembled, the chairs are attractive, sturdy, and can accommodate standing desks. They are good value for the money and I recommend if you need a standing desk.

A tale of two caveats:1. I did a lot of research to finally settle on this chair. But I guess I didn't do enough, because it turns out that, even at the lowest setting, it's just a tad too high for my workbench. The description says 20x20x42. But gives no indication what part of the chair is measured at 42 inches. So the description is useless. In any case, I'm here to tell you that at the lowest setting the top of the seat is at 31 inches, and at the highest setting, about 35 1/2 inches. Now why couldn't this company (or any of these chair companies) just say that?2. The instructions are an IQ test. For instance:A) there are two tubes that comprise the vertical supports. They are different sizes, but are given the same part number. So, which one goes below the footrest and which goes above it? You'll get no clue from the instructions, but I'll tell that if you want the footrest to be lower, use the shorter tube for the lower piece (the one that connects with the stand). I found out the hard way, and now my knees are up around my neck! (exaggeration :)B) You will pull all the hair out of your head until you discover that the upper tube (as above) must be pushed far enough through the footrest hole so that the lower tube will "stick" to it. If you don't get it right, the chair will wobble. I'd say you should push it through far enough so that the beginning of the taper is about an inch or so beyond (below) the hole.C) There are two parts that you'll think are missing. They aren't. They're just hiding. On the parts list diagram they look like two donut shaped parts about 2 to 3 inches in diameter. You'll be looking all over the place for them; rifling through the packaging, turning the box inside out. Just before you decide to send the chair back, you'll find that, in fact, they are only a little washer and a lock washer that are already in place on the chair-back support arm (they're on the screw/wheel that tightens the support arm to the chair back).D) Once you've assembled the chair it will NEVER, EVER come apart. Believe me, I tried to do it. Because the footrest was too high, I thought I'd just switch the two short tube for the long on. It was like the tubes and hydraulics were welded together. So get it right the first time!!Other than the above peccadilloes, it's a good chair. Sturdy (so far) and nice looking. Refer to number 2 above to help with putting it together, and as far as the height goes, I'd suggest putting some phone books or something on an existing chair to actually demonstrate for yourself how high the chair you buy needs to be.Good luck

Great product overall. I've ordered three of these for my office to use for standing desks. One for a tall person (6'3''), a medium height person (5'7'') and a short person (5'). The tall setting is a little sketchy and the first thing that is going to go is the top tube or at least it feels like it. It works great for a medium and short height person. It cannot be lowered to a regular desk height.We had a little trouble figuring out the two tubes that make the stool column. There are two sizes, one short and one tall and the manual does not differentiate between the two. You kind of have to figure out which one you want on top or bottom or if you're gonna use one or both. Keep that in mind when setting it up because it's a pain taking it apart again.One chair that we received was defective and a part was broken due to bad packaging. I had to return it and re-order a new one.
