How Do I Choose a Super King Mattress?

Choosing a mattress can be difficult, as sleep is a very personal experience. A mattress buying guide can help you weigh up all the different considerations. Here’s a closer look at some of the factors you need to consider before you buy:

Sleeping Position

The position you sleep in plays a big role in the firmness you should choose. For example, side sleepers should go for something with low to medium firmness. Your personal preference plays a role, but you need to ensure your body is being adequately supported throughout the night. 

Budget

Try and stick to the budget you set. Remember, it is possible to merge affordability and comfort together - you don’t have to compromise on either! At Memory Foam Warehouse, we’ve made it our mission to bring you high quality without the price tag.

Bed Frame

You need to make sure your bed frame can adequately support the mattress you choose. A weak frame won’t give you the comfortable night’s sleep you deserve. What’s more, you need to make sure the slats aren’t too far apart, as this may cause mattress sagging. Ensure your bed frame helps promote airflow also.

Why Choose Memory Foam Warehouse?

Our cheap super king mattresses never compromise on quality. We don’t cut corners around here! We’ve made it our mission to ensure our customers receive value for money each and every time. This is why we offer:

Price Match

Our mattress price match promise ensures you’re finding the best deals out there. If you find the same product for a cheaper price elsewhere - we’ll match it! So, you can sleep easy in the knowledge you won’t go over budget.
