Sleep technology

When we moved we had to buy everything from scratch, since we only moved with our suitcases. One of the things that I was quite keen on getting was a memory foam mattress that remembers your body shape and molds itself so that you are comfortable and well supported. I haven't got around to getting one of these, but since I've already got a really nice mattress, I'm planning to get a memory foam pillow instead, which function on the same principle. I find it really interesting to see how technology is being used in so many innovative ways, to increase our comfort and make life easier for us. Wonder what they will come up with next?
