Sea To Summit Comfort Deluxe Self Inflating Mat Large Wide


Imagine a sleeping mat so comfortable, you forgot you weren’t sleeping in your bed at home. With 10cm vertical side walls, and a flat sleeping surface thanks to our Delta Core™ foam technology, this is as close to a conventional mattress you’ll get while still being able to fit other items in your car/van or expedition size pack. With an R-value of 5.2, Comfort Deluxe S.I. Mats can be used in all but the coldest temperatures.

Perfect for car camping, or for extended base-camp style trips, the Comfort Deluxe range of sleeping mats will find you the envy of all your friends. Be warned: when pulling this one out for house guests - they may end up staying longer than planned. It's also ideal for van life and overlanding.

All of our S.I. mats use the first ever, multi-function single valve designed specifically for self-inflating mats. No more fighting re-inflation as you try to roll up your mat!

Sea to Summit Comfort Delux sleeping mattress

So impressed with the comfort and quality of this sleeping mattress, fast to inflate, and deflated easily - highly recommend

Deluxe Comfort - LOVE IT

By: on 9 September 2018
Just back from a few days sleeping on this mat. LOVE IT. I've had and tried quite a few mats over the years. From the popular Blackwolf to the 4WD self-inflates. It's light, very compact given it's 10mm thickness and width (though not suitable for hikers packing as light as possible). Feels like a mix of mattresses, a little bit of an air-bed, bit of a hiking mattress and a bit of a thick 4WD mattress. I did inflate a little more than what the self inflate did by itself and was very comfortable with no sore back. The one way valve is very handy (lesson learn't - just twist it around - don't pull out the orange bit!). Best mattress I have ever had camping - Highly Recommend.
