Best Super King Mattress: Add a Little Luxury to Bedtime

Do you often find your feet stick off the end of standard mattresses? Or are you often joined by an army of little ones in the middle of the night? A super king size mattress could be a simple way to solve your sleep dilemmas.

Being able to stretch out and roll over without disturbing your sleeping partner is a luxury we should all enjoy. To maximise your time in bed and wake up feeling refreshed, a little extra wiggle room may be all you need.

We’ve gathered together the best super king mattresses so you can find the right one for your sleeping needs.

Is a Super King Worth It?

What makes a super king size mattress so much better than a standard king size? If you’re looking for a little extra space and comfort in your bed, a super king comes with fantastic benefits.

You may want to opt for a super king if…

  • You often share a bed with your partner and children
  • You share a bed and are a light sleeper
  • You sleep with your pets
  • You move around a lot in the night
  • You spend a lot of time in bed
  • You or your partner are very tall or have a large frame
  • You have a very large bedroom in which a smaller bed would look out of place
  • You want to add a little luxury to your sleeping space

With a super king you have more space to stretch out and toss and turn without falling out of the bed! It also adds an element of luxury to your sleeping experience.

What Size is a Super King?

Super king size is the largest mattress size available from almost all mattress retailers.

A standard super king mattress size is 180 x 200cm.

To compare, a king size mattress is 150 x 200cm, and a slightly wider Euro size mattress is 160 x 200cm.

What to Consider When Buying A Super King Mattress

There are few things to bear in mind when searching for a super king mattress;

Your Bedroom Size

Clearly, an extra large mattress needs a larger than average bedroom. Cramming a super king into a small room would look out of place and leave little room for any other furniture.

However, a super king in a large bedroom makes a stunning focal point. It may even be worth sacrificing some furniture to make room.

Your Bed Base

You will need to buy a bed base to accommodate your new mattress. Luckily, we have a variety of super king bed styles for you to choose from.

The Price

Naturally, a larger mattress will sport a slightly larger price tag. This means weighing up the importance of price vs. quality of sleep.

Types of Super King Mattresses

Now you’re clear on what a super king can deliver, let’s turn our attention to the different types of mattresses available in this size;

Memory Foam Super King

A memory foam mattress provides a higher level of comfort and support than standard spring mattresses thanks to its innovative design. By moulding to your body on contact with weight and warmth, it provides personalised comfort and pressure relief.

Pocket Sprung Super King

Pocket sprung mattresses differ from open coil in that they are comprised of individual springs held within fabric pockets. This allows for extra movement, providing more support on pressure points.

Hybrid Super King

A hybrid mattress combines several different mattress types in one. For example, combing a pocket sprung base with a top layer of foam can create different levels of support for varying sleeping styles.

Orthopedic Super King

Orthopedic memory foam mattresses are designed for those who need extra support for their back and joints. Dense layers of support foam help to relieve back pain and other related issues.

Boxed Super King

A box mattress makes delivery easy and efficient. By compressing and rolling your mattress into a box, it can be on your doorstep in a matter of days. It also makes carrying it up the stairs easier- vital when you’re dealing with an extra large mattress!

Best Super King Mattress for Different Sleeping Positions

Whether you’re a side sleeper or a back sleeper, the way you sleep should be a consideration when buying a new mattress. Let’s take a look at the best mattresses for different sleeping positions;

Side Sleepers

If you tend to sleep on your side, the right mattress could help you maintain healthy spine alignment. Memory foam mattresses are a great choice for side sleepers as they provide a cushioning layer for your shoulders and hips, while giving you all the support you need for a good night’s sleep.
