Can we pay by purchase order?
Yes. Choose Purchase Order / Invoice at checkout. W-9 on request; tax-exempt orders accepted.
How fast does it ship?
Ships within 2–3 business days. Free UPS Ground shipping in the contiguous US.
Casters or glides?
Self-Braking Casters resist rolling while the stool is empty, then roll once someone is seated. Or non-marring glides, no wheels: the stool stays where it is placed. Both suit hard and carpeted floors.
Does it arrive assembled?
It ships boxed and goes together with press-fit parts; the procedure arm attaches with one set screw (2 mm Allen wrench). A QR code on each box opens the assembly instructions (also under Additional Resources).
Can one order mix heights, colors or feet?
Yes. Add each build to the cart, then check out once.
Can we send it back?
Yes. Get any chair or stool back to us within 30 days of delivery, and the return is on us. It needs to come back new and resellable, with all the parts and pieces in the original box.

"Exactly what we needed!"
"Dental assisting stool is a perfect match to our existing upholstery and seems very sturdy and well made. We mistakenly ordered the standard cylinder height and customer service was extremely helpful in helping us select the correct height."
