The beauty of the inflatables is the size they pack down to [roughly 5" x 10"with mine]. Some of the bigger more comfortable ones are as big as a normal carrymat when rolled for transportation but infinitely more comfortable and of course more expensive. It is all a trade off between comfort, price and portability, and therefore a personal choice. I've had my thermarest ten years plus now which seems quite cheap over that time period. Gelert do much cheaper versions but I have no experience of them.
