Anyone who has ever been in a serious relationship will know that having a cuddle in bed isn't always the most enjoyable of experiences. It's great for a short period of time, and then the numbness, tingling, or out-and-out pain kicks in. This is due to mattresses offering no freedom of movement for your arm and shoulder, and the solution may be simpler than you thought.
Mehdi Motjabavi has created the Cuddle Mattress, which he is hoping to turn into a viable product. As the name suggests, the Cuddle Mattress has been designed to solve any dead-arm-in-bed issues by creating the space the cuddling arm needs to avoid getting squashed.
The Cuddle Mattress is basically a normal mattress that has been divided into sections. There is a central section designed to support your torso, but the top and bottom ends have been cut into slices. When cuddling your significant other you simply slide your arm in between two of the slices to prevent any compression. Even when not cuddling up, this could be useful in helping you stay comfortable when sleeping on your side, or give you somewhere to stick your toes on cold nights.
Motjabavi has already tried the crowdfunding route to gain the funding needed to make the Cuddle Mattress a reality, but his Indiegogo campaign was unsuccessful. However, the Vimeo video he created to publicize the effort (embedded below) continues to generate interest, suggesting there is considerable demand for such a product. Motjabavi is now actively inviting investors and other interested parties to contact him in the hope that he can still bring the Cuddle Mattress to market.
