The opinion of Aventure Nordique

The Ether Light XR Insulated inflatable mattress from Australian brand Sea to Summit is lightweight and insulated. This mummy-shaped mattress is perfect for anyone looking for a lighter sleeping option. With a thickness of 10 cm, it is particularly comfortable. Length and width vary according to the size chosen.


Its R-Value of 4.1 means it can be used in all 3 seasons and more. Insulation is provided by a TRM insulating film that reflects infrared heat back to the sleeper. The brand has also reduced the size of the air cells, so there is less air circulation within the mattress when changing position, which increases the R-Value.


The construction with a large number of ‘Air Sprung Cell’ air cells provides comfort and support during sleep. The cells are joined together with TPU. In terms of comfort, this mattress is equipped with a system for holding a Sea to Summit pillow in place.


It is inflated using the pump bag supplied. This bag also doubles as a storage bag. The Xpress valve has a double stopper: to inflate and deflate very quickly. You can also fine-tune the valve manually.


To limit the appearance of mould inside the mattress, an antimicrobial treatment has been applied to the TPU construction. On the sleeping side, the Ether Light is made from 30/40 denier nylon (sleeper side/floor side), a lightweight, quiet fabric.
