How Big is a King Size?

King size mattress dimensions are 150cm x 200cm or 5’0 x 6’8.

Why Choose Us?

Each and every one of our memory foam mattresses are made from the highest quality materials at affordable prices.

Our entire range is made from the highest quality viscoelastic foam. This is an open-cell structural design that allows air to be inserted.

What Does This Mean?

This can balance body weight and provide effective support of pressure points in the body.

It also makes the material body-responsive, moulding to fit your unique shape and enabling you to enjoy an undisturbed sleep night after night.

Understanding Our Range

We have a wide variety for you to choose from, which ensures you aren’t limited to a narrow selection. We understand that sleeping experiences are very personal, with everyone having different habits and preferences.


Our cool memory foam mattresses are perfect for those who overheat during the night, as the fibres have been specifically designed for breathability.

Their superior quality aligns with your shape, moulding to you as you rest. Particularly when it comes to king sized mattresses, you won’t feel your partner at all as you sleep, as both your body weights will be supported.


Our Essentials memory foam range is our most basic, yet still offers optimum comfort levels. Here you can find the most affordable prices, without compromising on quality.

4G Aircool

Our foam 4G Aircool is another range that has been specifically designed with breathability in mind. As you sleep, the airflow will ensure you don’t overheat.

These mattresses also feature eucalyptus infused covers, making them luxuriously soft to touch.


Mattresses found in our Zen range combine various levels of memory foam. This eases joint pain, aligns your spine and ensures you sleep without tension.


Our Komfi memory foam mattresses are handcrafted masterpieces that gurantee luxury every night of the week. They even come with a 10-15 year warranty, showing you how confident we are of their quality.

The innovative design ensures you’ll sleep without being disturbed.

Making the Right Choice for You

You may have decided on the size, but there are many factors you need to consider to help you pick the mattress for you.

Here’s a quick mattress buying guide to help you weigh things up.


Usually, a mattress with a high density will feel more solid than those with a lower one.

When choosing - consider your preferences, do you like your mattresses firm or not?

Also consider your sleeping position. Stomach sleepers should consider going for something that isn’t too soft, as this could cause your spine to curve. Meanwhile, side sleepers or those who move around at night should opt for something softer.

Price Range

What’s your budget? Trying to keep this in mind will help you figure out how to choose a mattress.


Try to consider all the different factors of your bedroom, such as the bed frame, to help you pick.

It’s always a good idea to check the measurements of your bedroom to be sure the bed will easily fit. Ensure you’ll be left with enough space to move around the room!

Your Partner

Do you and your partner have significantly different body weights? Does one of you tend to overheat at night?

If sharing this bed with someone else - consider both of your habits. Doing so will make sure you both get a good night’s sleep.

Your Body

Do you suffer from any particular ailments or medical conditions? This could be arthritis or back pain, for example.

Try to choose a mattress that will assist with these; giving you the support you require.
