Your primary issue is you want GOOD and CHEAP. Those two things are usually mutually exclusive, especially when talking BIFL products that aren’t cast iron. Buckwheat pillows are a great fit for what you’re asking for and what you’re saying you need them for. However is sounds like you want someone to jump in and tell you Great Value pillows are the way to go.

Buckwheat pillows are literally ideal for all of that. I paid $100 for my buckwheat Hullo pillow and quickly had to buy my boyfriend one as he was so jealous. 5 years later they’re still in perfect condition.

Buckwheat pillows cost more and you have to dial it in, but they’re 10000x better than any other pillow I’ve found. Other pillows are the way the come, and they’re either perfect or not. With buckwheat you can make the pillow you want.

As for washable they’re incredibly easy to clean. Dump the hulls into a trash bag, wash the cover, dump the hulls back in, move on with your day. The washer doesn’t destroy your pillow. Should you want to replace the buckwheat filling for some reason that’s easy to do as well.
