Sea to Summit Comfort Deluxe Self Inflating Sleeping Mat

Note: This is a bulky product so shipping rates us for more info.


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. 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! Also available in double!


  • Delta™-Core™ Technology
  • Luxurious 30D stretch knit fabric for a soft next to skin feeling on top.
  • Robust and durable 75D polyester with extrusion laminated TPU used on base
  • Large horizontal triangular cores reduce the weight and bulk without sacrificing support and comfort. The large 10cm sidewalls creat a full width flat sleeping surface
  • PU foam is thicker on top of each Delta™ Core™ for better insulation directly under you. It also keeps top and bottom surface of foam intact ensuring consistent warmth along entire length of the mat and better bonding with shell fabrics
  • Diagonal supporting foam walls help inflate the mattress and creates a more compact rolled mat
  • 10cm thick
