We've had two IKEA sofas now and to be honest, I haven't been very impressed with them. The cushions have always needed plumping and the IKEA Friheten leatherette is far to slippy for words.
However, we loved it as a sofa bed while borrowing our brother in law's apartment in Spain a couple of years ago. Then by chance, we stumbled across it in IKEA one day when we were looking for a new sofa for our living room.
We've now had it nearly two years and the cushions are always slipping off.
