The Sigma is a truly uniquely designed contemporary faux leather bar stool. The barstool's stem, footrest, and base are manufactured from chrome-plated steel while the seat is faux leather-covered padded foam for a perfect cushioned seat. These stools also have the added feature of a gas lift strut mechanism as well as the ability to rotate 360 degrees. Sigma also has a protective base to look after your floor by preventing scratching with a lined rubber ring. The simple design of the seat means fits with any decor, so it is perfect for use in a kitchen, bar, or any other application. The short support at the back of the stool adds to the stability of the seat's occupant by giving an added assurance of safety. Each barstool comes complete with a chrome footrest and an adjustable gas lift tested to operate at least 100,000 times. Measures about 15" wide by 15" deep and adjust from table to counter/bar height (24" to 34" total height of 21.5" to 31.5" for the seat height). Footrest measures 11" wide and base diameter is 15". The backrest rises 2.5" above the seat. We have the best quality barstools of this type. Don't settle for a cheap imitation made of inferior materials. We are so confident in the durability of our product that we offer a 5-year warranty on the strut performance on all our barstools that we sell.
