My actual bed is OK but the mattress, duvet, pillows and linen have seen better days. I'd like to replace them all with something half decent (on a sensible budget) and would love tips on what makes for a really comfortable, inviting bed. In particular I'd like some bed linen that actually fits and looks nice for longer than 5 minutes - everything I've bought lately seems to be very poor quality regardless of where I get it and how much I spend.
