Comfort is fine,afterall it is a stool. The lower frame that connects the wheels are very weak. They bend over time. the company stood behind the product and replace it,but the same thing is happening. If the wheels catch when moving across the floor they start to bend over time. Wouldn't buy this again . I had another brand the piston gave out but not the wheel,will have to shop for another.

....and the vinyl wheels are nice and quiet. The stool goes up nice and high but i was hoping it would go down about 5-6 inches lower then its lowest position.....then it would be a very versatile stool

Seat is not very wide.

1. The cast aluminum base means it's lighter for the same sturdy stiffness. Lots of these rolling stools have bases made of chromed steel tubing, and the ones I've encountered tend to creak and flex a little as they get old. I'm sure there are steel tube stools as sturdy and still as this one, but they'd have to be a lot heavier. The aluminum gives it a classic look.
2. The larger wheeled roller-blade style rollers are the other advantage here. Compared to the small wheeled black plastic rollers you see on other stools, these roll and swivel silently, change directions smoothly and easily with no scraping as they reverse. Perfect for any lab, or service office, or shop, where you'll need roll the stool around to keep up with you as you work. This stool takes no effort to move about.
3. The gas-charged column works smoothly and quickly to adjust seat height. The chromed column is a color match to the polished aluminum base and fits into the base so that it looks seamless, but that's just how precision fit it is. That surprised me since machining is expensive and for it to slot into the base with perfect fit and then stay in place securely without a holding fastener all suggest a quality level that is good value for the price.
4. Same with the padded top. Some reviews complain it's too small but it seems right for a work stool--very comfortable for me (six feet tall) to sit and work. Also comfortable was the density of the padding which seemed perfect. I'd seen reviews complaining about the padding being too hard and too soft, but I found it perfect for a comfortable work stool.
5. Installation took one or two minutes--a) place each roller post into one of the five base feet. b) Remove red cap from the gas-charged cylinder and drop the column into the precision machined hole in the base. c) Drop the fully assembled stool seat onto the gas-charged column.
6. All this fits so well that you can pick up the stool by its top to move it or carry it.

Sturdy rolling stool. Perfect for my job in nursing homes. Rolls very well.
