The weight of a superking mattress depends on the comfort and support materials used inside of the mattress. For example, a mattress with pocket springs and natural fillings or memory foam will be much heavier than a mattress with pocket springs and soft white fibres.

A heavier mattress is usually an indicator of more premium materials and craftsmanship.

It is important to know the weight of your superking mattress because all bed frames and bed bases have a maximum weight allowance. Using a mattress that is heavier than the recommended weight could invalidate the guarantee or warranty of your bed.

How big should a room be for a superking mattress and bed?

As superking mattresses are the largest mattress size available in the UK, they are ideally made for master bedrooms.

Your room needs to be big enough to fit the dimensions above, but it is also dependent on the size of the other furniture in your bedroom and how much space it takes up.

• Latex superking mattresses are similar to memory foam mattresses in that they contour to your body, but latex bounces back much faster than memory foam and offers more pressure-relief.

• Gel foam superking mattresses often have more cooling properties than other mattresses due to their open-cell structure.
• Reflex foam superking mattresses offer great comfort and support on a budget.
• Pillow top superking mattresses feature an additional layer stitched into the top of the mattress for extra comfort.
• Zip and link superking mattresses are made up of two single mattresses zipped together, which can be unzipped at any time to form two single beds.

Superking mattress features:

• Orthopaedic superking mattresses are perfect if you suffer from back pain as they provide excellent lumbar support and promote healthy spinal alignment to aid pressure-relief.
• Rolled-up superking mattresses arrive at your house vacuum-packed in a box for your convenience.
• Single-sided superking mattresses only need to be rotated every 3 months.
• Double-sided superking mattresses need to be flipped and rotated every 3 months.

• Medium to firm superking mattresses - this firmness is ideal if you prefer a firmer sleeping surface but still want a slight sin-in feel

How often should I replace my superking mattress?

You should replace your superking mattress every 7 years, according to the National Bed Federation guidelines.

Your mattress guarantee or warranty may be longer than these 7 years, but it is still important to check that your mattress is still:

• Hygienic
• Providing the same levels of comfort as before

Like any furniture, mattresses experience wear and tear, and after sleeping on it for 6 to 9 hours every night, your mattress will become dirty and will not provide as good a night’s sleep as it used to.

How will I get a superking mattress to my bedroom?

There are a few different ways you can get your superking mattress to your bedroom.

• If you have purchased a rolled superking mattress, then your mattress will arrive vacuum-packed in a box. This makes it super easy to carry your mattress to your bedroom.

• If your superking mattress is going to arrive flat, there are some things you should remember for your safety and to avoid damaging your new mattress:

1. Before you start to move your mattress, make sure that the path to your bedroom is clear so you don’t risk injury
2. Ask someone to help you lift your superking mattress. As a superking mattress is heavy, you should not lift it alone
3. If possible, ask a third person to help direct where you going

• Here at Mattress Online, we offer a Premium Delivery service where we deliver your mattress to your room of choice for only an extra £20. Read our Delivery page for more details on this service.

Can I use my new superking mattress straight away?

Yes, if your superking mattress arrives flat (not rolled-up), you can sleep on it straight away.

If you choose a roll-up mattress, you'll just need to give it a few hours to expand to its full size. The exact length of time you need to wait will be explained in your mattress care guide.

Can I use my current bed with a superking mattress?

You can use your current bed with a new superking mattress if it meets the following criteria:

• You have a superking size bed base or bed frame
• Your new superking mattress does not exceed the weight limit of your bed base or frame - if you use a mattress over this weight limit it can invalidate your bed guarantee or warranty
• Your bed base or frame meets the base guidelines of your new mattress - some mattress brands prefer that you use a solid or platform top divan base, or a slatted bed frame with a specific slat gap width, to avoid invalidating the mattress guarantee or warranty

You can find the relevant care information for both your bed and mattress in their product care guides.

Do I need a specific bed frame for a superking mattress?

As we have mentioned above, you do not need to have a specific bed frame or bed for your superking mattress but it does have to:

• Be able to support the weight of your mattress - you can find this information in your bed’s care guide
• Match the bed base that is best suited for your mattress - you can find this information in your superking mattress’ care guide

How do I transport a superking mattress?

If you want to transport your superking mattress in a vehicle, you should:

• Make sure that you use a superking mattress bag to keep it safe
• Use a van or large vehicle that can store the mattress without bending it
• Keep the area around the mattress clear to avoid damaging it

Please remember: If you are moving a superking mattress, you should always ask someone else to help you. They are very heavy and having another person to help is much safer.
