UPDATE TO THE UPDATE: Despite me measuring multiple times before ordering, when the SnugStop pillow arrived it fell right through the same gap between mattress and bedframe my other pillows have been falling through. Do not recommend.
@jalefkowitJason Lefkowitz pillow gap is not a void to ever be filled, it is a mouth to always be fed, pillow gap forever hungers, but not for bland pillows, no, bland pillows merely sustain, pillow gap savours the tasty cricks and delicious aches from your neck when you wake up never rested
