Mama D

 from Oakland, NJ– Verified Buyer

Perfect sandbox for my 2 and 4 year old boys. The cover is sturdy but agree with other reviewers about placing a large ball underneath it to pitch the cover so rain water doesn't pool up.

 from CO– Verified Buyer

The kids enjoy this! One of the straps broke on the cover. You need to remove the side seats before covering. Also if you put a large ball in the middle, then put the cover on, it keeps the rain from getting inside.

It's great!

 from Grafton, WI– Verified Buyer

It's smaller than what I wanted it to be, but my grandson enjoys it anyway.

 from Evington, VA– Verified Buyer

Spent a lot of time looking at different boxes, brands, and reviews. Would go with this again. Do not have anything to compare it to but quality is great! Even the cover is just fine. Read in some reviews that the cover is bad but I disagree. Purchased for sons third birthday and do not regret! We just finished building our new home with nice new landscaping and the box fits right in. Definitely recommend!

Super High Quality and Attractive!

 from Los Angeles, CA– Verified Buyer

In my opinion, this is the best sandbox out there! Looks great! SO easy to assemble (just make sure you follow the directions pertaining to the numbers on each piece. The side pieces look the same but they are not.)! So high quality! No maintenance required - no need to waterproof. Very sturdy.

Square Sandbox with Cover

 from Owensboro, KY– Verified Buyer

The cover is the main reason I purchased this product and it appears that it will stand the test of time.

 from Belleville, IL– Verified Buyer

I think it's a bit overpriced. Not a bad purchase though - wish the cover was more durable and the design was a little more sturdy (could use cross-members). Overall though, I'm satisfied with the product. My grandson (4 years old) spends a great deal of time playing in it per week. I would purchase it again unless I found one that addressed the issues I highlighted.

Just perfect! And it arrived so fast. Great product! We have it on our covered deck and the kids spend hours playing in it.
