possibly looking for the impossible here.... but wanting to get some comfy seating for the conservatory - problem is, like most conservatories, it is cold in winter and hot in summer (we are looking into quotes to replace roof and make it a useable room but so far they are £££££'s and we might have to save a few years first) 
I don't want rattan furniture (not my taste at all) but a sofa that is big and comfy but not ridiculously expensive as its going into a cold (and sometimes therefore dampish) room
Any ideas (with pics and links if at all possible) Thanks
