The Exped MegaMat 10 LXW King Single Self Inflating Mattress has been designed to deliver at-home comfort anywhere in the world. This incredibly supportive open-cell foam paired with the honeycomb-embossed tricot stretch surface work together to offer you an experience akin to memory foam, ensuring that you'll sleep through the night on any surface. Striking the perfect balance between supportive strength without uncomfortable rigidity this design is an absolute winner for those that suffer from sore backs on the campsite. Unlike most self-inflating mats on the market which slope and taper at the edges the Exped MegaMat 10 has vertical sidewalls. These allow the surface material to extend all the way to the edges along the entire length of the mat to resemble the comfort of your bed back at home. It also prevents you from sliding off the edges during the night. The Exped MegaMat 10 comprises materials that are Oeko-Tek 100 certified. This means that it has passed Oeko-Tex's rigorous testing to ensure that all the textiles (from yarns to the finished product) are free from harmful substances to minimise any environmental impact, so you can protect the outdoors while enjoying them in the utmost comfort! Superior comfort is paired with a durable design in the incredible valve technology utilised by this mat. The flush design sets them into the three-dimensional vertical wall which eliminates potential damage that can be sustained by protruding valves. The inflate valve has an additional feature that allows you to burp out small amounts of air to adjust your comfort level even when you are lying on it! The separate deflate valve is supersized to enable it to purge massive amounts of air very quickly, resulting in a speedy and fuss-free pack up. For the serious camper that likes to head out into the wild with the best gear on hand, you can't look past the Exped MegaMat 10 LXW King Single Self Inflating Mattress.
