NEMO Roamer Self-Inflating Mattress review

The Roamer is not an air mattress in the guest-room sense: it is a self-inflating foam mattress that combines open-cell foam with air. NEMO says its 4 inches of cushioning feel close to a bed at home, and the numbers back up its purpose: an R-value of 7, which means it insulates you well from cold ground, and a packed size of 14 by 8.5 inches for the Single. NEMO's Flow Core construction cuts horizontal and vertical air channels into the foam so it inflates and deflates faster and packs smaller, and the Laylow valve lets you fine-tune firmness while a separate dump valve speeds up packing. A Vortex pump sack comes in the box, so no power is needed. The Single cost $259.95 on NEMO's US store when we checked, and Single and Single Wide pads have toggles and loops to join two for couples. It costs far more than a PVC air bed and sits only 4 inches high, but for regular car campers it is warmer and more stable.
