VIVO Saddle Stool with Wheels, Ergonomic Swivel Chair for Dental Office, Massage Clinic, Spa Salon, Height Adjustable Hydraulic Stool, Mobile Sitting Balance Chair with Padded Seat, Black, CHAIR-S03SD

Promotes Active Sitting – Saddle-style seat centers your weight and engages underused muscles while encouraging a more natural angle for your spine, helping to reduce the pressure in your hips and across your back.
Height Adjustable for Comfort – The stool adjusts 21” to 29” for the most comfortable angle. Please Note: Since you will use different muscles on this stool than you normally do, it’s best to use the chair in increments, combining it with regular sitting or standing for those who have active workstations.
Easy 3-Step Assembly – No tools are required for this simple assembly process. Just insert the pole into the corresponding holes on the base and seat, and it’s ready to go! The sturdy aluminum and steel frame supports up to 280 lbs with ease.
Smooth Mobility & 360 Swivel – Transparent, gliding caster wheels are silent in motion and create effortless movements around your workspace. The seat features 360° of swivel for additional flexibility.
We’ve Got You Covered – This ergonomic saddle stool is backed with a 1-Year Manufacturer Warranty and friendly tech support to help with any questions or concerns.
