I’m a side sleeper fo lyfe and I once went on a road trip with my wife out west. We stayed with her aunt for a night and I slept using whatever pillow and bed was in the guest room.
I had the best sleep of my life and located the tag on the pillow, looked it up and purchased the pillow so it’d be waiting for me at home when I got back. Been using it for like six years ever since. It’s a Sleep Innovations Reversible Gel... https://www.amazon.ca/dp/B0073CIVTK?ref=ppx_pop_mob_ap_share. I use a second pillow for my knees and I can’t recommend doing that enough too. For a side sleeper, a knee pillow is key.
I can't find it on the website but it should be something like a Novaform hydroluxe comfort memory foam.. its ~$35 CAD and is just flat like this: https://www.amazon.ca/Sleep-Innovations-Reversible-Memory-Pillow/dp/B0073CIVTK/ref=sr_1_1?s=kitchen&ie=UTF8&qid=1504579439&sr=1-1&keywords=novaform+memory+foam+pillow
I'll double check if I swing by this week.. sorry I can't be more help ATM
We both really can use This Pillow Who doesnt need a good nights sleep and in summer it will keep our Noggins nice and Cool
