We were originally planning to purchase the Hensvik crib, but we decided on the Gulliver instead. We are fortunate enough to live just a few miles from an Ikea location, so we examined all of the crib models in the store. Both the Hensvik and the Leksvik have an additional board between the slats and the rails, which causes a gap around the entire perimeter of the mattress. The floor models both had huge gaps, which we were just not comfortable with. The Gulliver does not have this extra board, and the mattress is a very tight fit. Once we got it home, we were very pleased with how safe and secure it is, and it was even less expensive than the other two models.
