The Panda Kids Memory Foam Bamboo Pillow is a 10cm-deep memory foam pillow inside a removable bamboo cover, and on paper that should mean a slow, moulding feel that doesn't squash flat under a small head. Owners describe much the same thing. One nine-year-old's review says "you only sink slightly so gives good support". On heat they're less agreed: several say it doesn't overheat, but one adult using it wrote that it "Makes my head too hot".
The soft, eco-friendly bamboo cover cradles your child's head, while the memory foam provides all the support they need for a good night's sleep. The parent of a six-year-old wrote that it "Bounces back to shape after head has been on it", which is what you want from memory foam at this size. And to top it all off, this pillow is antibacterial and moisture-wicking, so it will help keep your child's pillowcase nice and clean.
The Kids Memory Foam Bamboo Pillow is a supportive, high-quality pillow that is highly breathable and wicks away moisture. For me, it feels like a good shout for kids who like that gentle, slightly 'huggy' feel around the head and neck, especially if they get a bit warm at night.
That said, memory foam is still memory foam, so if your child really hates that slow-responding feel, they might find it a bit odd compared to a bouncy fibre pillow. Panda grades the feel medium-firm, and owners split on that. One boy said it "feels quite hard when you touch it but feels really nice on his head", while the parent of a four-year-old thought it "maybe a bit too hard". If your kid needs a higher loft (or tends to sleep right on the edge of the pillow), it can feel a touch low. And while the bamboo angle is nice, I'd still be washing the cover regularly because 'antibacterial' doesn't mean it stays fresh forever.
