Ok, so I bought this about 8 years ago, so I couldn’t find the exact one, but this is the closest I could find on Amazon: https://www.amazon.com/dp/B000Q8JTVC?psc=1 I also didn’t pay that much for it, if I remember it was ~$35-40 (the most I’d ever spent on a pillow lol). You might be able to find a lumbar support tempur pedic pillow and use it for your head since they make them smaller.
I also realized that I have this, which I’ve used for traveling https://www.bedbathandbeyond.com/store/product/therapedic-reg-memory-touch-round-neck-pillow/1013506582 and used it to sleep on airport benches. It doesn’t have the same height as a pillow and I would probably stack a towel or extra clothes underneath for long term sleeping. If you shop at BBB you can always get a 20% off coupon online or in the mail too.
Hope this helps!
