Inflatable lumbar pocket

It can be very comforting for the more lordotic members of our species to have relatively large, soft objects placed in the small of their backs. Such objects include hands, hot water bottles and cushions. Other people, however, prefer not to experience cushions. Therefore, many garments should have two sealable vertical lumbar pocket openings. This would allow a companion to caress the small of the back, facilitate the insertion of a small cushion, perhaps roggy or otherwise warm, and double as a sealable, inflatable air cushion in its own right in order to prevent the discomfort experienced by many as a result of cushion absence, removing the need to buy large numbers of cushions or experience discomfort in less comfort-oriented spaces such as waiting rooms and park benches. There should also be tubes running up to the collar to enable the wearer to blow up the cushion when required. It'd also warm the kidneys.
