I read the reviews but was still a little sceptical about the comfort of a mattress that is delivered rolled up.  I could not have been more wrong.  Delivery was prompt and timely; packaging was easy to undo and the magic of a thick, medium/firm full size super-king mattress unfolding on the bed base was amazing.  It only took a few minutes. Thereafter followed a comfortable and supported night's sleep and now, after 4 nights of comfortable sleep I know that I made the right decision.
