My husband and I had pretty exacting standards when it came to buying our new mattress, and, after reading the reviews felt it was worth taking the long trip to the Button & Sprung showroom. Within minutes of being there we were so impressed we decided to buy a Camelia bed as well as a mattress. The mattress we eventually chose was a Perendale (normal tension) which seemed cloud-like to lie on after our old one. When it all arrived, our bedroom was transformed with the new bed but the mattress seemed firmer than we recalled. We continued to try it for some weeks but although it softened slightly we eventually took up B&S's suggestion to exchange it for a softer tension version as part of their guarantee. Now we are completely happy with the result - this is the first time in years I have been able to sleep on my back the whole night. This mattress is a godsend! In retrospect I should have spent longer in-store trying out the mattresses and perhaps considered a softer tension in the first instance. It is hard to to make such a critical purchase in a short time-frame but Button & Sprung were so helpful their glowing reviews are completely justified. I would not hesitate buying from them again or recommending others.
