Topstar ST79S10 swivel stool Sitness 27 / upholstery fabric black / footplate wood with stainless steel cover I ordered the chair a few days ago, because I wanted a higher stool, with whom I can better tap half standing and working at the desk. So I ordered the Sitness 27, which can be adjusted to 69 cm height. There is probably also a to 84 cm, which I had originally considered, but would I now probably too high, I am 190 cm tall, and because of to 69 cm is just right. It was assembled in 10 seconds, the tires were a little inflated. Here one takes the best instead of accompanying small bicycle pump a proper pump which also indicates the pressure, because you have the pressure of the tire (the one with the beautiful chrome cover does not see) regulate yes by its own weight. The chair is sturdy, the cushion very pleasant, the work is fun! It is handy and not difficult, you can slide it around at any time and put away. I use it in parallel with my very good office chair of Pending. The little brother I had dabbled in a furniture shop (which could have these higher chair only order, with 4-6 weeks delivery time, as want to keep up there?) And the tested seat-principle, but that is not really necessary. I am quite sure: As everyone sits wonderful and active! I'll furnish my family gradually with the chairs!
