User questions & answers

Question:	The minimum seat height says 23" and maximim is 30". Can you tell me where the 23" is at? Bottom or top of seat? From the front or back
Answer:	Doubt it it will hold 310 lbs, at least NOT safely. The stool itself is fine, however, since it is the seat is high (and its support is somewhat shaky), I wouldn't recommend this stool for someone heavy ...
Question:	What are the dimensions of the drafting chair? Specially the arm rest and seat height range
Answer:	This was about 27-31. It was the tallest chair I could find. **disclaimer... This chair is really low quality. The arms it came with were flimsy plastic I didn't even leave on. The back loosens often and wiggles ALOT... No real support. Finally the plastic broke where the caster insert... I'd recommend a different chair.
Question:	What is the seat height range for the tall drafting chair, not the normal desk chair
Answer:	The seat sits 24" from the ground at its lowest and 30" from the ground at its highest.
Question:	how high does the seat go and is the foot ring adjustble in height also
Answer:	Low position is 24 1/2", high position is 31". ( I did measure it again after reading response 1, and it is 31"). I use it at a 36" high bench and suits my needs perfectly. It is well constructed, the fabric is really heavy duty and stable. My only complaint is the foot rest is not adjustable which I did not realize when I purchased it. But all in all it works great for me.

User questions & answers

Question:	What is the weight limit for this chair
Answer:	Standard weight limit for any non rated chair is 250 lbs. This is as such for this chair.
Question:	can you add a head rest to the chair
Answer:	Yes you can. The head rest that works with this chair is the Lorell LLR85562. I used that same model on my chair (an officestar proline II) and it fit perfectly. You simply pop off the two caps in the holes on the back of the chair and install.
Question:	Is this chair really helpful if you have lower back pain
Answer:	I bought 2 of these, one for me and one for my son. I would not buy them again, they are not comfortable at all. They may appear to have many adjustments, but they don't seem to adjust to any comfortable position. The seats are hard and the chair itself is very big and built like a tank, and they are heavy. If you are over 250 pounds, it might be a good buy. I would not buy another one. As far as lower back, this chair is only normal/average support, there are no lumbar adjustments.
Question:	Can someone please give the seat height dimensions. Like from the floor to the top of the chair on back side of chair. and from seat to the top of the chair on the inside? thanks

User questions & answers

Question:	What is the tallest seat-to-floor height available in this model
Answer:	I have 23" to the top of the seat at the highest point.
Question:	How long can you sit in this chair until you feel pain? Also, how is the lumbar support
Answer:	I end up sitting in the chair for 8 and a half hours a day at/for work. Once you monkey with all of the adjustables, it's more comfortable than the chair I used to have in the office I moved from. The lumbar support feels to me like it's a little low even at its highest position but it's tolerable.
Question:	What is the seat height
Answer:	The seat goes between 17.5-22" inches from the floor.
Question:	What is the lowest seat height from floor to the top of the chair
Answer:	I measure approx. 18" from the floor to the highest point at the top edge of the seat.Chris
