Our grandson's birthday gift was a big hit with adults too.  Fast, easy set-up, high quality in design and materials.  Roomy with storage.  And surprise, it's also a monkey bar to the 5 year old. Our (43 lb.) boy often hangs from the center bar. No bending, no breaking. Now that's a sturdy design.  With the protective cover, the neighborhood cats stay out.  We are very pleased with this canopy covered sandbox.  We may soon buy a second for his cousin.  Highly recommended.
