Sea to Summit's Comfort Plus™ Insulated Mats provide the most effective system for fine tuning the level of comfort available in any air mat today.When Sea to Summit set out to design a mat that was better than what was already available, they ultimately went back to why we carry a sleeping mat into the wild in the first place — to give us a better night’s sleep. ‘Better’ is of course a very subjective ambition and while they could have made the lightest, or the most compact mat ever designed, they are stoked to present what they consider to be the most comfortable sleeping mattresses available.    Features and Specifications Sea to Summit's Comfort Plus™ Insulated Mats employ dual layer technology with Exkin Platinum® and Thermolite® insulation.The two layers of high resolution cells can be pressurised independently to provide ultimate flexibility in comfort adjustment. Inflate the top layer to your personal comfort while maintaining a high pressure base layer for protection from rough terrain. Independent chambers allow the mattress to function even if one of the layers is punctured.

It was so comfortable, in fact, it earned our Top Pick award for Comfort once again. To those who have spent nights out sans pad or on a deflated sleeping pad, the redundant air chambers represent another level of durability. It's not only ultra-comfortable, but the dual air chambers almost guarantee you won't be sleeping on the cold hard ground. This redundant chamber system is unique to the Comfort Plus, making it ultra reliable but also quite a bit heavier than comparable sleeping pads." Outdoor Gear Lab, 2020    Frequently Asked Questions Q. WILL MOISTURE BUILD UP DAMAGE MY MAT IF I INFLATE IT WITH MY BREATH?A. Absolutely not. We have gone to extreme lengths to ensure that the fabrics and coatings that we have used in the construction of our Air Sprung Cell Mattresses can easily withstand the moisture build up that could occur from inflating them with your breath. We have also carefully treated our internal coatings to ensure that microbial life cannot replicate in a moisture rich environment, thus removing the chance that your mat may become moldy. Q. WHAT’S THE BEST WAY TO INFLATE MY AIR SPRUNG CELL MATTRESS?A. STS Air Sprung Cell Mattresses can be inflated in a number of ways. We have been very careful in using a TPU laminate on the internal face of the fabrics that has been manufactured with an anti-microbial treatment. This means that you are able to blow your mattress up by mouth without risk of mould growth inside the mattress. If you prefer not to huff and puff when setting up camp, we have created the Jet Stream Pump Sack and the Air Stream Dry Sack to make your life easier. Q. HOW DO I REPAIR MY AIR SPRUNG CELL MAT?A. Every mattress comes with a repair kit containing a number of patches. These self-adhesive repair patches can be used on holes up to about 2 mm in diameter with complete confidence. If you have a hold larger than this, please contact STS enquiries as to the best way to effect a repair. Q. WHAT DO I DO IF WATER OR MOISTURE GETS TRAPPED INSIDE MY MATTRESS?A. Having a small amount of moisture trapped inside your mattress is not a major issue, and the moisture will not damage your mat in anyway because of the anti-microbial TPU lining. You should, however, give your mattress an opportunity to dry out when you get a chance. The best way to achieve this is to hang the mat in a warm and dry environment with the valve open. Q. WHAT’S THE BEST WAY TO CLEAN MY STS MATTRESS?A. Mild soap and water is the best way to try and clean any dirt or grime off your mattress. The external coating on the face fabric will ensure that cleaning is quick and effective. Be careful not to use any strong cleaning products or bleaches, as these will damage the fabrics and potentially compromise the integrity of the mattress.
