I bought a couple of 4-legged, “ball-bearings under the seat” bar stools about 2 years ago. I’m 240#, 6’2” and both stools have “ground” almost completely to a halt in their swivel function. I was getting a leg workout trying to turn either one from the bearing failures. This product has the bearings inside the post. #1- This swivels effortlessly and the footrest swivels with you, a great idea. #2- Height adjustment is smooth and easy. #3- Pedestal base is sufficiently wide to be stable but I have this on a rug so can’t speak to any sliding on a wood/vinyl floor. #4- Seat is lightly padded but not uncomfortable and the material looks good (brown vinyl for mine). It could use thicker padding on the sit-down side for the price. #5- Only 4 parts to assemble. #6- Footrest is reinforced by angled metal buttresses at the ends, not just ring-ends welded to the post. It should hold up to downward pressure much better. Mostly all positives.The bad: #1- Absolutely NO assembly instructions or any documentation in the box. Perhaps it was an oversight but I have to review what I got. That wasn’t a problem for me until I had to attach the seat to the post. The post seat-mounting plate is welded on with a backwards tilt of 5-10 degrees and the 4 screws/washers come with 2 different thicknesses of hard plastic spacers, one about twice as thick as the other. These are obviously meant to compensate for the tilt of the mounting plate when attaching the seat but there’s no guidance as to which goes in front and which in the back or why. These people seem to think all the buying public are engineers. I placed the thicker ones in back, between the plate and the seat, and then inserted the screw thru the washer then thru the plate and then spacer, screwing it all together into the bottom of the seat. Of course, I did the same with the thinner ones on the front. This seems to work fine and is stable but is it correct? I can’t know for sure and time will have to tell. Do not over-tighten the screws! Just snug them up. #2- The top of the hydraulic post comes with a black vinyl protective cap. It isn’t obvious that this must be removed for installation (not all of us are engineers, remember) so I foresee multiple future complaints since the adjustment won’t work with it still on because the post WILL still fit in the bottom of the seat plate post with it on. A nickel’s worth of included paper instructions can avoid this. Again, short-sighted. #3- Although each of the 4 parts are individually well padded for shipment, there was zero protection between the parts themselves or the box. Again, ten cents worth of those daisy-chained air pockets would help against puncture thru the box or an edge of the seat plate finding a way to dig thru to the seat upholstery. Cheap as extra shipping protection and you’d think Zuri would know from experience that if it can happen during shipping, it eventually will.Overall, if this holds up over the next few months, I’ll buy another one. If it doesn’t, I’ll update my review with that. Right now, I can recommend the assembled product.Update: I finally got an email response from the company, acknowledging the missing instructions and including a PDF of the missing booklet. I actually had placed the seat spacers opposite front to back from the directions but can't feel why I should bother to change them, since the spacers are only 1/8" difference in thickness. This is a very nice seat so far; a smooth swivel and a comfortable heel-hanger that stays aligned with the front as all of this rotates and a slick looking stool. 4 stars to 5 stars as a product.Update 2: The padding on the stool seat is just too thin to sit in very long. I have had to add a memory foam cushion to last more than 20 minutes on it. 5 stars down to 4.
