Purchased in 2024 along with twin sheets in hopes to eliminate (my 2 year old at the time) night sweats. It makes a huge difference and has held up wonderfully through many washes and many chocolate milk spills that even the pillow didn’t recover from. I wash it once a week and the chocolate milk (even after sitting for a week) comes right out every time with no pretreatment interventions. It’s still in like new condition despite being used every single day for 2 years. My son is now 4 and his “cold pillow” a staple. He takes it everywhere and will ask for it every single night before bed.
