I don't think so. They may appear more trendy these days as so many people have them. I had one back when my children were small and that was over 20-25 years ago, so they've been around forever.

Still fashionable.

Definitely not. I would however consider how long you plan on living in the house as many people seem to move and they don't fit in the new room

Fine in casual rooms - but if it's your only seating area - not sure if I'd want to be snuggled up quite so close to a virtual stranger who's come to chat to you about insurance or something !
Also - often a designers nightmare to squeeze in an existing non changeable handed one !!

If they were outdated furniture retailers wouldn't sell them. There are loads for sale. I have one in my other home in Somerset and my son has just ordered one to be made in grey in the same design. While he was ordering his 3 more people ordered the same one. They are very popular.
