Lounge doorway is 81cm wide with door on, and would be 82cm if could take off. Very old fittings that seem to have been painted over many times so getting door off may be an issue. Doorway height is 196cm Hallway width is 77.5cm and height wise no issue in hall - very high ceilings. The hallway width is probably the biggest problem. The only access to lounge is through this hallway door, and the width is only 77.5cm. The Next team were trying to twist it around but the sofa was just too big. They actually ended up accidentally putting a hole in my wall trying to do it!

May I suggest you email Ikea with these questions? Or call their customer service. I personally wouldn’t buy a sofa, sofa bed or bed without trying it out in store first. Read the reviews for the sofa-bed - are they mostly positive? None of my sofas are identical, but they are a similar colour. It still works.

would be careful about the type of leather, as there are different treatments which applied and can make a difference to longevity. we bought analine leather couch, very expensive but didn't know that although soft and comfortable it didn't take too well to every day use and hot body! it was our only couch and we had a his and hers side.......his side the leather darkened and after 5-7 years cracked, now ripped. only resolution, cotton blanket over the seat and back cushions. Recovering both seat and back cushions will be as expensive as buying again.... 3 years after quote we are no closer to deciding as it is a damned comfy couch and styles have moved away from classic to stiff and angular! Hint - do some reading on the leather types....

I think you could go various ways. I like the rug, can it go under the sofa feet? (Hard to tell how wide it is from the photo). The art seems a bit small, it often works better if it's hung just a few inches over the sofa to connect with it. I'm not sure if this art is big enough though as 4 seater sofa sizes vary. I'd probably repeat the brass for a coffee table or floor lamp and then I've picked up colours in the art for cushions but maybe vary the texture with linen etc rather than just all velvet. I think it will look great once furnished and accessorised 😊
