The need for proper breast support is not something I face on a nightly basis, but according to this commercial, gravity causes one breast to rest on top of the other (oh no!) resulting in discomfort, cleavage wrinkles, and improper spine alignment for well-endowed women. Luckily, there's a plastic cylinder on the market that offers its support.
The ad for Kush Support calls it a "comfortable nighttime companion," which makes one think that "breast supporter" is just a euphemism for a more kinky plastic cylinder device! Either way, it better do something magical — it costs $55!
Would sleeping with this thing between your breasts help you get a better night sleep?
