Sofa is about 79 to 86" wide, I don't have the other dimensions in front of me, the ceiling's are only about 9 ft high. Why do you ask ?

Thank you so much for answering! Love the design, am wanting to do something similar to this! Do you know how tall the cabinets are on either side?

30 - 32" give or take, arm hight is about 29". Thank you and good luck !
