Imo, and only after I have spent $600 in 2 years on different pillows, just stay with he box store options. Maybe not the $7 pillows, but $20ish. Don't fall for gimmicks, I tried cooling pillows (polyester cover on a regular polyfill) , adjustable cluster pillows (literally filled with foam trash), memory foam (too hot, hard, and odd to roll over), feather/down (too thin for side sleeping) and a few others. What I, personally, found is that an extra firm polyfill $20 no gimmick pillow from target is 1000% more comfortable for me (135lb side sleeper). I can roll over without having to readjust it or wait for foam to reshape, and when it gets flat in 8 months I'm only out $20. I do like to have an extra plush/soft pillow on the bed just for sitting up reading, but that can be any old cheap-y. Hope this helps, good luck!
