I hope DFS have changed their policies
Some time ago, we ordered a 3 piece from DFS, and after giving the measurements at the showroom was told that there would be no problem and paid a £100 deposit. On delivery, they couldn't get it up our stairs and we lost our £100 deposit as it was 'specially made'. This was normal for DFS at the time, and all I can say is that if anyone orders from them, make sure your measurements are spot on, and ignore the salesperson. Explain if there is possible difficulty in delivery. You have been warned.
