Height: Approximately 28cm Width: Approximately 23cm Depth: Approximately 11cm Please consider these measurements as a guideline, as they are approximate. I purchased this for use at daycare and used it for about six months, but I no longer need it due to a move. There is some wear and slight staining, and one of the two zipper pulls is missing, but it is still usable. The back is made of mesh material, and you can put ice packs in the area with the Velcro. I think it's a helpful item for the park or outings, especially as it gets hotter. Thank you for your understanding. Please note that I will fold it up for shipping.
