The Therm-A-Rest BaseCamp Sleeping Mattress is an exceptionally comfortable sleeping mat for year-round use. Its larger size and thick padding make this an excellent choice when a good night's rest is your main priority.

While the design of other sleeping mats is often based around keeping the weight and pack size down, the focus here is on warmth and comfort. As such, the BaseCamp mattress is ideal for those travelling by vehicle or situated at a static camp, for whom a little extra weight and volume is not an issue.

With a full 5 cm of padding, this mattress provides a high level of warmth and support, even when sleeping on your side. The BaseCamp mat is based on a straightforward, workhorse design that has been providing dependable comfort under the stars for over 40 years.

Crafted on a foundation of time-tested materials and components, the BaseCamp mattress is surprisingly light, compressible and now softer than ever thanks to a recent change in fabrics, making it an even better travel companion.

The versatile self-inflating pad features the high-performance WingLock™ valve, allowing the pad to inflate three times faster thanks to a larger opening and one-way inflation.

  I bought the Thermo rest sleeping mattress for my son, for Christmas. He loved it. Excellent product and I totally recommend it. I am also pleased with the five star service I received when I telephoned the Woodlore shop to ask advice before purchasing.
