Armchair Brianne Swivel is modeled according to existing, real-world furniture, which you can find on: www.houzz.com

The whole armchair has a fabric material, whose color is changeable if you put the overlay factor in the shader editor on 1.

The swivel construction has a dark wooden material.

The whole model is not joined in one mesh. It contains several parts, which are parented to an empty object.

Just mark an empty object, and snap your whole model where you want.
