Great for small apartment!
Purchased for a first apartment. It was a little more complicated to put together, but not too terribly difficult. It was perfect for the small space. Has been the perfect gift!

Perfect for organizing kids’ essentials
Size: with legs
I really like this EXPERLAM 8 Cube Storage Organizer. It was fairly easy to assemble and feels stable once put together. The design is simple and clean, so it fits nicely in our home.
I’m using it mainly for my children’s toys, and it works great. It helps keep everything in one place instead of toys being all over the room. The cube size is very practical for different types of toys, books, and storage bins.
Overall, it’s very useful for organizing a kids’ space and makes cleaning up so much easier. Definitely happy with this purchase.

Great storage for kids’ room!
Size: with base, Size: with base
It took me about 30-40 minutes to assemble, and it wasn't difficult at all. It fits perfectly in the kids' room, and finally, all the toys aren't scattered all over the floor 🙌
The baskets are roomy, they hold a lot of stuff, and my kids can easily pick up their toys and put them back (well... sometimes 😂). Plus, it looks very neat and modern.
I'm very happy with the purchase; the room is much more organized now 👍
