All sections are interchangeable! Mix and move them around. Super clean hardly used. No pets no kids. About a year and an half old, bought new but it does have feathers in the cushions and I just can’t morally get past it. Trying to recoup some money I spent on it, total a year ago was $2300 for the set. Right now it’s going for roughly $1985 before tax. So it’s selling for the same price I bought it for. I have moving/lifting straps and will gladly assist in moving it to your vehicle.
