Thermarest's Prolite Apex self inflating mats have the best warmth to weight ratio of any self inflating mattress thanks to the StrataCore insulation foam technology. This also keeps weight and pack size to a minimum. 

Therm-a-rest says:

Boasting an unrivaled warmth-to-weight ratio, the Apex is the pinnacle of light and stable self-inflating comfort.

The newest addition to our tried-and-true ProLite family adds warmth and thickness without adding additional weight. The lightweight Apex offers year-round warmth and comfort thanks to its unique StrataCore construction. The two-inch thick mattress ensures that you stay comfy during your backcountry backpacking and camping adventures. Stuff sack included.

Therm-a-Rest's ProLite Apex Regular Sleeping Mat is 'self inflating', that is, you open the valve and leave it to slowly suck air into it and inflate. You usually have to add a few breaths by mouth at the end and then close the valve...and sleep. This mat self inflated quickly and the 5cm thickness combined with the internal foam gives a comfy and supportive mat.

Self inflating mats have foam sandwiched between two outer fabric layers. The high quality outer fabric is soft to the touch and tough at 50 denier. The foam inside is also high quality that will survive repeated compression cycles and the valve has been tried and tested over many years.

Self inflating mats are considered to be more durable  than insulated air beds though not a slight  and if you do get a puncture you still have a layer of foam to lie on - with airbeds you would have nothing. The stuff sack has compression straps to minimise pack size.
