Well our new leather sofas were finally delivered today and we managed to get them in fairly easily. Given their size (c. 2.4m long), I'd decided to remove the door and door frame linings in the lounge and alter the front door so that the side light on one side of it also hinges open, thereby adding about an extra 20" of access width. I'm so glad I did as it made the whole process so much easier than would have been the case and I was the delivery guys' best mate.
I've already replaced most of the woodwork I removed and altered the doors of a leaded light built in cupboard in the lounge so they open bi-fold and are no longer interfered with by one of the sofa backs.
Just got to complete the woodwork to the front door framing and I'm done aside from moving my rather large Wharfedale E70 speakers into their new location.
The sofas are great, huge and ever so comfy. If they last half as long as the ones they replaced I'll be very happy.
