It also gives your child the correct back posture while they sleep. Sealy mattresses blend support with comfort so that your child sleeps well, helping further with their physical development.

Should I buy a Sealy memory foam or latex mattress?

This comes down to individual preference and need. Both provide the back, neck and joints with support when pressure is applied and then the mattress returns to its original shape when pressure is released. Latex is an elastic material and tends to spring back into shape much quicker than memory foam. Both are incredibly comfortable, but if you want a more responsive mattress, latex is the better option.

This type of mattress is constructed from Posturepedic springs. This means that the springs are connected in rows via a coil, and can move independently of each other, resulting in a mattress that sculpts itself to your body, providing excellent support.

The Posturepedic mattress is also recommended for those who are restless sleepers as the mattress helps you to maintain a comfortable sleeping position. The Posturepedic is Sealy's most popular mattress.
