How to choose the best Double Mattresses

What size is a double mattress?

Most commonly, standard double mattress dimensions are 4 ft 6 inches wide and 6 ft 3 inches long (135 x 190 cm). If you purchase a double bed frame, this is the standard size that you will need to fit. Double mattresses are widely available and are the most common bed size in the average UK household. This 4ft6 double is particularly popular among couples as they can comfortably accommodate two adults, plus, they work great with our range of double divan beds.

What is the difference between a double memory foam and a double pocket sprung mattress?

Our two most popular double mattresses include memory foam and pocket sprung technology. However, there are key differences between these two that you should factor in when purchasing your new product.

Double pocket sprung mattress

Pocket sprung mattresses are formed of 1,000 - 2,000 individual springs. These springs move individually to provide more comfort to the body's contours when sleeping. Double pocket sprung mattresses tend to be bouncy, which is perfect for those that prefer a springier feeling as opposed to a sinking feeling. Pocket sprung mattresses are great for ventilation and regulating heat. The spring and fibre combination allows air to move freely and create a comfortable temperature throughout the night.

Double memory foam mattress

Double memory foam mattresses are on the firmer side and are ideal for those that prefer a bed they can sink in to. The material transforms to the shape of your body's natural contours for a more tailored sleeping experience. Double memory foam mattresses are particularly great for couples that vary in weight. Because the memory foam adapts to your body, it's a great all-around mattress. Providing support and sinking where needed. A completely custom experience for any shape or sized person. Both styles have their strengths and as always, it comes entirely down to personal preference.

If you’d rather a different type of mattress, other popular options include latex mattresses, orthopaedic mattresses and mattresses with natural fillings, which are ideal if you suffer from allergies.

How firm should my double mattress be?

The firmness of your double bed mattress comes down to a lot of factors. Such as your weight, what position you sleep in or if you suffer from back pain.

An easy way to decide your ideal firmness is with your weight. The heavier you are, the firmer your mattress should usually be. More often than not, you and your partner are probably different weights. The best way to combat this is a double memory foam mattress as it adjusts to your body's natural contours.

Another way to decide on how firm your double mattress should be is your sleeping position. If you sleep on your side, a softer mattress is advised to keep your spine aligned. And if you're a back sleeper, a medium to firm double mattress is recommended. If you are suffering from back pain, it might be a good idea to try an orthopaedic mattress. These are designed to support the joints and back correctly. Eliminating back pain caused by sleeping.

How often should I replace my double mattress?

As a general rule, the Sleep Council recommends replacing your standard double mattress every 8 years. However, it's best to use your judgment. If there is visible dipping in the middle, or if you can feel the springs through it, then it's time for a new one. If your mattress is pinging or creaking when you move it's advised to get a replacement.

To prolong your double bed mattress lifespan, its recommended to rotate it 180 degrees every 3 months. This is because we often sleep in the same spot on the bed every night which leads to general wear and tear. Turning the mattress essentially gives the side you slept on a chance to recover and spring back to life.

Mattress protectors also help increase longevity and prevent the risk of dust build up. Which in turn can cause allergies, bed bugs, and illnesses to arise. In general, protectors are there to keep your mattress hygienic and feeling like new for longer.
