I know I saw a thread on this in the past, but I have been unable to find it. I have to sleep on my side and have pretty bad shoulders. Need recommendations from experienced side sleepers on which pad they have found to be the most comfortable, durable and best for backpacking. I am not worried about the price, and I don't want an air mattress that can spring a leak. Will mainly be used for summer and fall trips. Thanks for the help.
