Firm Mattresses

After you've determined the ideal bed size/mattress size to suit your bed frame, it's time to give some consideration to the cushioning of the sleep surface.

Contributing to the quality of your sleep is the volume of body support a new mattress provides, depending on your spine health. A firm mattress can be an ideal choice for individuals who sleep on their stomach, due to the additional support helping to keep your spine aligned.

For different sleep configurations, we also have a range of medium mattresses and plush mattresses.

The firmness combines with other comfort layers and technologies to aid in an incredible sleep such as pocket springs and memory foam.

Want to explore the full selection of bed sizes from Appliances Online? Feel free to check out the range of king single mattresses, king size mattresses, and queen mattresses.
