I have a couple of cooling mats for ZoE.
A smaller one that I put in her stroller during outings on hot days, and a larger one for home. They are cool not cold. She will lay on it when she's warm, but if she's really hot, she prefers to go lay on the marble floor of the bathroom.
Here's ZoE on her big mat. I ordered it from Fosters & Smithh.
