Bought a 2 and 3 seater designer sofas

We bought a 2 and 3 seater sofa, very little difference in size between 2 or 3 seaters. Could have been explained better at the time of viewing/ordering. The delivery period was extended several times, order had to be corrected from what was on the invoice to what had been ordered. Product quality is good, but very expensive and add-ons such as cushions are expensive.
