The quality of your baby’s sleep reflects directly on his or her quality of life and on yours. That’s why you want to give your little sleeper the best sleep system around and that’s the Stokke Sleepi System III. This complete sleep system takes your child from birth to the age of seven and then neatly separates to convert into two stylish chairs that you can use for years after your child is sleeping in a “big-person” bed. As an infant crib, the Stokke Sleepi System III’s oval shape mimics the comfort of a mother’s womb. Its lack of sharp corners is safer for older siblings as well, and is space-saving too! The Stokke Sleepi System III comes with a special Welun polyurethane mattress whose foam offers an open-cell structure, allowing for better ventilation so that your child doesn’t get overheated while he or she sleeps. After your child outgrows his or her crib, the Stokke Sleepi System III converts to a toddler bed with its own mattress. When your child is about five years old, the Sleepi System III converts to a Junior bed with a matching mattress. Crafted from the finest quality European beechwood, the Stokke Sleepi System III is simply the finest bedroom plan you can buy for your growing child. It’s not simply furniture it’s an investment.
