Easy to assemble although I suggest watching a YouTube video to start more easily. It is very big with a satisfactory mattress, comfortably fitting all three of my children inside.
The only negative thing it could have for its price is at least some handles so that the child can lift themselves up. It does not disassemble so you can easily transport it anywhere.

Easy assembly. Very spacious and the little one fits in there nicely. The mattress is durable! I used it at a party with several babies and kids and it held up! I highly recommend it!
