Let's be honest. Kids do a lot more than sleep in their beds. The bed in your child's room is a play surface, a seating area, a lounging cushion, and the moment your back is turned, a trampoline. Knowing the abuse that your kids' mattresses are going to take, you may be tempted to opt for the least expensive mattress and box spring you can find. That, according to sleep and bedding experts at Simmons, is a big mistake. According to conservative estimates, children will spend up to 40% of their lives in or on the bed in their room. Simmons Bedding Company, which has spent decades examining sleep patterns in adults, has turned its eye for detail on the way that children use - and abuse - their beds. The result is the Simmons Slumber Time range of mattresses designed especially for children and teens. Among the special innovations that Simmons has built into these mattresses are: - Surround Around Edge system which provides extra support around the edges of the bed for seating - because kids are as likely to sit on their beds as lie on them. - No Flip Design, so you don't have to wrestle with mattresses to flip them over every few months. - RiteHeight option mattresses and foundations designed specifically for bunk beds and trundle beds. Simmons Slumber Time mattresses come in three different comfort levels - Firm, Plush and Pillow Top - designed for the comfort of every child in your house, from the tough little tomboy to the princess who can feel a pea through 20 featherbeds.
