I purchased this pillow in the Queen size Extra Firm and it is, by far, the best pillow I've used in a very long time (and I have a lot of back and neck problems and have tried A LOT of different pillows). It's firm enough to support my head and neck but without being so firm that it's uncomfortable, and maintains it's shape very well. Great for both side sleeping and back sleeping. I have not machine washed it yet, so I cannot attest to that feature, but highly recommend this pillow!
Comfy and the firmness stays
