He keeps moving to the kitchen floor. A dog that's too warm gets up, circles, and lies down on tile because it's the coolest thing in the house. Then he gets up again ten minutes later, because tile is hard on the hips. This ice silk pet cooling mat is cool to the touch the moment he lies on it, with a raised edge to rest his head on, so he gets the tile feeling without the tile. What the cooling mat is made of: Ice silk surface: woven to feel cold on contact, so there's nothing to freeze, fill or plug in Breathable through the middle: layers that move air rather than trap it, so heat leaves instead of pooling under him Cotton bolster edge: a soft raised lip on the sides, so he gets neck support without losing the cool surface Non-slip granules underneath: the base grips tile and hardwood, so the mat stays where you put it Machine washable: the whole mat goes in, so a summer of use doesn't end in the trash Four layers, not one sheet. Ice silk on the surface, cotton at the bolster, a second ice silk layer and high-elastic filling beneath, so the mat keeps its shape and its airflow rather than flattening into a warm pad by August. Cool to the touch, and it stays put. The honeycomb weave holds micro air pockets and the granulated base grips the floor, so he can throw himself onto it without the mat sliding across the room. Three gradients, same mat. Blue, yellow and black are the same build in different fabric, so the choice is about your floor, not about how well it works. Getting the size right Three sizes, S, M and L. Measure your pet lying stretched out on their side and pick the mat that fits that length with a little to spare, so they're fully on the cool surface rather than half on the floor. The measurements are on the size chart in the product images. Specifications Surface: Ice silk cooling fiber Filling: High-elastic PP cotton with a cotton bolster Base: Non-slip granulated, waterproof Power: None, no gel, water or electricity Care: Machine washable Colors: Gradient Blue, Gradient Yellow, Gradient Black Safety note: A cooling mat is not a treatment for overheating. A pet that's panting hard, unsteady or unresponsive needs shade, water and a vet, not a mat. Check for tears if your pet digs at it, and remove it once the filling is reachable. Put it where he already goes to cool off, and the kitchen floor stops being the best spot in the house.
