A sofa bed is extremely practical and functional because it is a bed and sofa in one. Within no time at all you turn a sofa into a bed without the hassle of a separate mattress. Saving space and comfort are the most important properties of a good sofa bed, but that doesn't mean you have to compromise on style and design. Go for a beautiful corduroy or velvet sofa bed to give your living room or bedroom an instant eye-catcher. Go for classic grey if you want a sofa bed that fits in with any interior style.
