I’ve spent seriously over $1k on pillows in the past year because I kept waking up with neck pain and headaches. I’ve tried A LOT of foam-based pillows but this is like no other. Firm enough because I’m a side sleeper and my other pillows tended to go flat during the night, but not so firm that it wasn’t comfortable. It’s the perfect balance and it doesn’t retain heat at all which I was concerned about. This is definitely not typical memory foam-it’s so much better and hard to describe. If you’re on the fence you should purchase it. You won’t be sorry. I have also purchased the mattress topper which is also amazing. Great customer service, too. I highly recommend both the pillow and mattress topper.
