COSTWAY Ergonomic Drafting Chair, Height Adjustable Stool Swivel Office Chair with Backrest and Adjustable Footrest, Mid-Back Leather Padded Rolling Stool Task Desk Chair for Home Office Studio, Black

OK it's plasticky and cheap, but it is surprisingly well made, easy to assemble, and works perfectly. Smooth action air valve. My photos are highest and lowest possible. It is a bargain, extremely well packed, and I give it 10/10.

I have a standing desk.Sometimes, I need to have a bit of a break and this chair soles the problem.I can sit down without having to adjust the table.It's way better than I imagined it would be. Strong, comfy - looks good.If you have a wooden floor - you will need a matt to stop propelling yourself across the room.This comes highly recommended.

Arrived via courier less than 24 hrs after ordering. Took 10 minutes to put together. Nice comfortable chair and ideal for my workshop / mancave. Great service too.

A new try out as a chair to suit my standing work-station.Easily built with the minimum of fuss. I had the seat assembeld in around 20 mins.Casters are a push fit - It may be worth fitting a better type either the roller blade type which I have found to be terrific if a little too free running - just right for the office chair grande prix. Or something more 'heavy duty'.The floor I have the chair on is slopped - consequence of 2" (50mm) fall across the length of the room in a 200 year old house. So a set of mushrooms is possibly the next move.Seat is a little small but fits OK.Backrest is fixed height.This is one of the few chairs with a variable height foot rest normally these are welded at a height to suit an eight year old.This is one of the advantages of this seat, and was important to me as I want to be comfortable not hunched over a keyboard with my knees at an angle that brings on cramp.edit>I did manage to provoke cramp it is important to stand up from time to time to stop the sudden and agonising cramp in the thigh.< I will be more active in future the seat is a little small and it may be the angle this takes with your leg that triggers cramp.I am also expecting this seat to survive longer than 512days...

Is not a cheap chair!. I've expected it more sturdy. Is making noises from the day one. I hope not to have any surprise.Shame... is a good size chair.EDITED:After 4 months of hard use is still together, that's a good thing, is noisy but still working.

A little higher than I thought but nice chair and works fine

Very sturdy and comfortable chair well pleased

Was looking for a high stool to use with my fixed stand up desk. Needed a stool that raises higher than most and this is perfect. Assembled easy without instructions. Instruction are supplied.
