I am moving to a new flat, problem is the bedroom is really small and I need to find a mattress (double) with a length shorter than the standard 6 feet, can anyone help? Do they sell foam in HK with that size?
Try pricerite and ofcourse ikea. But don't get the big beds if you're not sure whether you'll be moving alot. Get those fold-up futons or sofas, they're cheaper and alot more flexible to your future environment; whatever they might be. I wouldn't suggest buying used mattress, don't know where they've been.
