The iXoft Notebook Cooler is like a table mat with thermal capacity. Lightweight and bendable, it supports notebooks ranging from 12” to 17”. It is made of two layers of fabric with a chemical solution sandwiched in-between: sodium sulfate decahydrate (Na2SO4.10 H2O), also known as Glauber’s Salt, a heat storing substance used on hot/cold gel packs. The surface is grainy because of the sodium sulfate decahydrate crystals inside. Underneath it has a suede coating that is very comfortable and soft when resting on a user’s lap. The sandwich edges are reinforced with thick embroidery so the Glauber’s Salt – who liquefies under intense heat (more about that later) – doesn’t spoil all over the pad.
