The Stokke Xplory Cup Holder comes with an adapter that fits perfectly on the Xplory handle. It is made of polyamide (a very sturdy plastic quality) in the same grey shade as the Xplory seat. The cup holder can take bottles/cups up to approx 1 liter/2.2 lbs in a varieties of sizes and shapes thanks to its clever design. We recommend that you only use it for cold drinks due to the hazard a warm cup of liquid can do to a child's skin if an accident should occur.
