When I originally read reviews of this product I felt very discouraged because a lot of people said that the legs made the co-sleeper unstable. I have NOT had that experience at all. The legs were easy to install, click together, and the co-sleeper feels just as stable as it did before. It is really nice to have these to be able to customize the sleeper to fit our taller bed. That being said (this is a review of the company and not the product) I really feel like this kit should be included with any co-sleeper and/or should cost much less. It seems awfully expensive for what it is.
