Hello christjne, I am just getting a few images for you.. Hold on.. Oka do some that are rather good.. Also their faux flower collection is really good. This one is from them and also their velvet in Porridge and Pale Sage could be nice along with Mole colour and Caviar is one they have too that would work possibly... .. There is also the option of throws and they have one in Mole and you could also think of stones and other shades of earthy tones... Group with 1 plain mole colour to give accent but I'd say 1 of each together on 1 or 2 sides and a throw or two for the sofa.. You may find some others you like too.. They also have Mirrors and the Cesario large could be very nice, it has a nice bevelled frame with dark wood and accent of gold that would be gr8 with the dark sofa.. All depends on budget as I have many more suggestions including antiques but for something under the one roof as it were... : ))

The big red rug had to go (we still don't know where to sell it), it ended up taking up the entire space, covering the wooden floor. The husband was heartbroken--it was from his flat as a bachelor, but we couldn't make it work. Yay! Would love to take you up on that offer because we are quite overwhelmed and don't quite know where to start!

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....

Looking at the overall pic I think your room would really benefit from a large soft rug and a coffee or side table or two as well as the cushions that you queried. Loaf has lovely linen and velvet ones and the colour co-ordination is almost done for you as they only do sludgy colours. I would avoid pattern. Consider some small long rectangle ones for back support when sitting on the sofa. A mix of shapes is good.
