Clothes Airer

I have one that opens up like an umbrella without the fabric cover. I actually use it to hang things on when ironed but, I think it would do just as well for what you want.

Is the roof of your conservatory strong enough to take one of those 'old-fashioned' ones that hangs from the ceiling? You'd get plenty of hangers on one of those and some of the modern ones are quite stylish.

Meant "items"!

I prefer the folding airers like the "HH Home Hut Laundry Airer 2 3 4 Fold Tier Clothes Horse Drier Indoor Drying Rack Folding (4 Fold)".

Sorry I can't post a link but this one is on Amazon too.

You can hang items on a hanger in the corners where each wing meets. It's very stable as long as the wet items are evenly spaced and the tiems are at a long enough distance to each other to dry properly indoors.

I have a different style of airer, similar to this one.

For smaller amounts of washing, the wings fold back over the centre, but for a large wash it has a lot of space - and everything hangs without touching anything else, so dries faster.
