The right mattress is essential to a good night’s rest, and this is especially true for young children. In fact, the proper mattress can help support your child’s posture and even affect bone strength, and it can help encourage deep sleep cycles that are necessary for good health. Because high-quality mattresses last up to 10 years or longer, it’s important to find one that grows with your child and can accommodate developing bodies. To choose the perfect mattress for your child, you simply need to consider the same factors you would look for when buying a mattress for yourself.
