Help Trying to find a chair!

Hello Fellow Redditor. Ive been desiring and looking for a chair for years. I know exactly what I want but cant find anything. I own an Ikea Millberget chair. The only negatives are that the chair doesnt have head support and the arm rest front support is in the way, it digs into my legs when sitting criss cross.

What Im looking for in a chair is:

1. Faux Leather or similar material to the Millberget chair.

2. 45"-49" back length for head support.

3. Arm rests from 6 1/2"-10" hight for better arm and shoulder relaxation. Anything 9 1/2"-13" is too high and pushes up my shoulders.

4. Flat seat or slightly raised on the front so that way your not angled too high. No curves on the sides because i sit criss cross alot and it isnt comfortable.

5. Good Cushion like the Millberget chair.

6. Flat back support! No curved sides to where your shoulders are forced to be curved inwards when sitting.

7. Foldable arm rests are on but the arm rests can be similar to the Millberget chair as long at the front support is further back.

I truly wish I could customize my own chair but I have no Idea how to without it costing $400 or more. Im willing to go up to $250 on a chair if it meets all of my requirements.

Thank you if you take the time to help.
