Tommy is a 2-level playpen that can be used for both play and sleep. The upper level is suitable from birth until 3-4 months, when the baby starts to lift themselves up. After that, you can use Tommy for sleep with the addition of the appropriate mattress.
It features a removable second level with a zipper and large side windows to monitor the child while they play. The side opening with a zipper will make it easier for the child to get in and out on their own when they start to crawl.
