Selling our sofa due to house move. Love this comfy sofa. Can be split and arranged in any formation. There is an extra arm rest extending the with by 25/26cm if you wanted to add it. The height measurement is to the top of the back cushions... height of seat measures at around 45cm. Happy to wash the covers before pick up as they are machine washable. I think you are still able to buy new covers from IKEA in a variance of colours. This sofa cost us around £550 new and is only two years old. Pick up only. Moving date is the 10th April.
