It was in a tent at Hyalite Reservoir when I finally gave up any hope of getting sleep while being pinned between two miniature inflatable rafts that my nieces were using as makeshift mattresses. Never again, I vowed! Now they each have a NeoAir All-Season inflatable mattress from Therm-a-Rest, and we all get better sleep. The NeoAir is a perfect year-round mattress, utilizing thermal technology to keep the twins warm even on cold, hard ground. An ultralight 2.3 oz. mini-pump is included—a $40 value—which pumps the mattress to its 2.5-inch thickness in mere minutes for outstanding comfort and convenience. Available at Bob Ward's and Timber Trails. $150; thermarest.com.
