Curve back of chair with arm curve

[Clare]

I'm trying to make this chair object and don't know how to get the hight difference back to front. Can someone please help. Thank you 

Operating system used: Mac Intel-based ventura 13.5

You could SEO it, or use a rotated Shell with a canted side.

Thank you. What shape would you recommend for the SEO a circle?

Are you talking about the seat itself? If you really need to show a slope for that, I would use a Roof or a Mesh, no SEO required. For the backrest, you have currently used a Wall to model it? If that is the case, I would use a Roof to SEO the top off.

Ling.

Thank you Ling. I will try this. Curves on curves I'm finding very difficult. Thank you for you time.
