I think I saw one thread in the past regarding bass stools. The relative merits of bar stools v. no stools v. other types of seating were discussed. Someone mentioned that they used the Quik Lok D-739. I looked on Quik loks' web site (www.quiklok.com) and found this model along with the D-749. Seems to me that the D-749 is the same as the 739 but adds the backrest. Key dimensions: Seat size: 12.4"D by16.3"W. padded Seat hight: adjusts from 22.2 to 33.6" weight: 15.5 lbs. Lists for $159.99 but I've seen it for about $100 at Zzounds. This is one recent review from some guy who uses it with his telescope as an "observation" chair: "It's here! . . . . It came disassembled, but it took only fifteen minutes to put together. Made by Quik Lok in Italy as a musician's chair, it is constructed of heavy gauge steel, painted flat black. It has a well-padded seat of generous proportions, a padded back rest, and a foot rest. There are "grippy" plastic grips/plugs on the footrest and the ends of the cross members that form the feet. These plugs and grips will allow the chair to remain stationary when in use. The fit and finish is pretty good, with only a couple of flaws in the paint or rough edges. The literature describes it as weighing 15.5 pounds, so it is well constructed and quite sturdy. The website says it is rated at accepting a load of 250 pounds, which sounds about right. The seat's height adjusts from a low of 23" to as much as 32" high with the seatback installed, and about three inches higher if it is removed. Although I didn't set the seat up at its extreme highest adjustment, I'm not sure it may be entirely safe at that height. This range of adjustment will fine for my particular needs, although someone else might have different requirements and should be aware of the chair's range of adjustment. The seat is comfortable, but does not have springs or gas struts supporting it. The bracket that attached the seat to post and allow for adjustment does its job securely, but has enough play built into it that the seat rocks a little. This might be a bit distracting when one is concentrating at the eyepiece, but it is not unsafe. The footrest adjusts easily and is a welcome feature, but it has a little slop in it, too. The movement in the seat and the footrest is not large, but care must be taken when shifting in the seat so as to avoid small jerks that might cause one to lose track of the object one is observing. On the whole it is reasonably well-made and will be fine at supporting an oberver at the telescope in comfort. It is possible that it is a little less refined than more expensive chairs, but it is as much as $100.00 cheaper than some of these chairs, too, which is fine with me! I believe it will suit me fine for now and will be a nice addition to my setup." I have back problems (who doesn't) and think I need something a tad more cushier than a bar stool. Comments??
