Seat Lock

This is a great design that utilizes two-piece locking hinge collar system for superior throne base to seat connection and oversized wing nut for easy and secure tightening. TAMA removed the "wobble" which can typically affect the seat to throne base connection.

1st Chair Height Adjustment

1st Chair thrones offer the best of both worlds-the exact height adjustment of threaded rod thrones with the fast adjustment of T-bolted systems:

1. Loosen the bolt (A) and raise the threaded rod to the approximate desired height (it's not necessary to get the exact height at this point).

2. Screw the Height lock (B) down to the top of the nylon bushing.

3. If a minor adjustment is necessary, simply turn the Height lock or rotate the seat.

4. Tighten the bolt (A) firmly.

Backrest

Both the height and angle of the backrest unit are adjustable, giving you the supoort you need no matter how you sit. And now there's another user-friendly feature: you can fold the backrest itself onto the seat without disassembling it for easier transport. The backrest unit is also sold individually and fits on all 1st Chair thrones.
