With three modes to use as your baby grows–bedside co-sleeper, free-standing baby bassinet, and safe baby play yard–the Mini Ezee 3-in-1 is the embodiment of what Arm's Reach is all about. It's easy to assemble, and portable too! It's easy for diaper changing; it features side pockets for storage, a 4-inch sleeping nest height, and a co-sleeping attachment strap and plate to provide the safest sleep solution for you and your newborn. After years of customer feedback and product developments this is truly an ideal option for any concerned parent. The Co-Sleeper brand bassinet in co-sleeping mode should sit flush against the parental bed mattress. Federal standards require no more than a 1/2 inch (13mm) gap between bedside sleeper and adult bed. If you have a bed with a platform, you will not be able to use the co-sleeper mode. Age Limitations: The bedside sleeper modes are only for an infant up to approximately 5 months in age or when the child begins to push up on hands and knees, whichever occurs first. Move your child to another sleeping product when your child reaches this stage.
