Can I use a new Sealy mattress on an old base?

Absolutely, there is no rule that says you have to use a new Sealy mattress on a new bed base. However, be sure to carefully check your new mattress size so that it will fit your existing base, and that the base can comfortably support your new mattress. Your existing base should be in good working condition, and remember that if you are purchasing a heavier mattress, check that it can support this additional weight. If your base is old, then it is probably best to get a completely new Sealy bed and mattress.

How do I choose a Sealy mattress for my child?

We have a range of children's mattresses that are all from the Posturepedic range. This is because this type of mattress provides the best support for your child's development. 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. For best results, buy the mattress and base at the same time. Then for added security choose a padded headboard.

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.

Will a Sealy mattress help me if I have a bad back?

All Sealy mattresses offer excellent support to the back and joints. Sealy undertakes constant and innovative research in their mattresses' construction to provide the absolute best support possible. This dedication is shown by the fact they established the OAB (Orthopaedic Advisory Board), a group of orthopaedic surgeons and other medical professionals. So, you know you're in safe hands.

What are posturepedic mattresses?

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. This mattress differs greatly from the traditional open coil mattress as these springs are not as supportive. 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.

Do I need a new Sealy mattress?

This is evident in just how much variety there is available these days. While your old Sealy bed will be of high quality, the newer models will be more valuable and provide greater comfort.

When replacing my Sealy mattress, do I need to buy a new base too?

A mattress and its matching base are designed to work together to give you the most comfortable night's sleep possible. Therefore, when you buy a new mattress, you should get a new bed base too.
