SIL has just been on the phone discussing her new sofa. She has got a bargain in the sales, apparently. She has had her previous sofa for 3 years. She asked us when we'd be replacing ours.
We've had our furniture - a large 3 seater sofa and a smaller 2 seater one - for 16 years. I remember it vividly as it was delivered when DS1 was a newborn and he's just had his 16th birthday. It's still comfortable. It's brown leather which I know some people think is desperately naff but it's stood up to 3 kids and still looks fine. We had the cushions refilled and some stitching redone about 5 years ago. SIL is horrified. She's had at least 4 sofas in the time we've had ours.
On the other hand, I'm not a fan of chucking out and buying new just because someone has decided that fashion has changed. Surely you keep things until they fall apart or are no longer fit for purpose rather than buying new "just because"?
(And it's not a money thing, we could afford a new one if we wanted to. But we don't).
