What are the dimensions of a standard uk double mattress?

Most commonly, when you come across a double mattress the standard 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 mattress that you will need to fit. Double mattresses are widely available and are the most common bed size in the average UK household. A standard UK double mattress is particularly popular among couples as they can comfortably accommodate two adults.

How often shall I turn my double mattress?

Rotating your double mattress is key to prolonging its lifespan. 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. In general, mattresses should be rotated every 3 months but you will need to use your judgment. If it feels like your side of the double mattress is becoming misshapen, rotate it 180 degrees and it will return to its correct form. Flipping the mattress regularly will lead to even wear throughout the mattress. Avoiding those dreaded lumpy bits.

For guide purposes only. Always check the specific instructions that came with your mattress.

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

With so many types of mattresses available it's important you choose what's right for you. There are key differences between a memory foam mattress and a pocket sprung mattress that you should factor in when purchasing a double mattress. Pocket sprung mattresses are formed of 1,000 - 2,000 individual springs. All of these springs move individually which provides more comfort to the body's contours when sleeping. Double pocket sprung mattresses tend to be bouncier. 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 through the mattress and create a comfortable temperature throughout the night.


Double memory foam mattresses are on the firmer side and are ideal for those that prefer a bed that 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 of mattresses have their strengths and as always, it comes entirely down to personal preference.

How firm should my double mattress be?

The firmness of your double mattress comes down to a lot of factors. Such as your weight, what position you sleep in or if you suffer from back pain. It's definitely not a one size fits all kind of purchase. An easy way to decide your mattress firmness is your weight. The heavier you are, the firmer your mattress needs to be. A general rule of thumb is a firm mattress is best suited to people 16 stone and up. 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 great 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-firm mattress is recommended. If you are suffering from back pain no matter what mattress you choose. It might be an idea to try an orthopaedic mattress. These types of mattresses are designed to support the joints and back correctly. Eliminating back pain caused by sleeping.

How often shall I replace my double mattress?

As a general rule, the Sleep Council recommends replacing your double mattress every 8 years. This is because, in 8 years, most of the fibers will have worn down and the mattress won't provide the same comfort and support it originally did. Although this guideline is helpful, it's best to use your judgment. If there is a visible dipping in the middle, or if you can feel the springs through it, then it's definitely time for a new one. Another sign is a loud mattress. If it's pinging, creaking and groaning when you move it's definitely time for a replacement.

Another reason you should replace your double mattress is if your body changes. If you become heavier or lighter your mattress might start to feel uncomfortable. When your mattress starts to feel uncomfortable, it's best to replace sooner than later to avoid sleepless nights or back problems. If you believe the mattress is deteriorating quickly (first year), check your warranty and get in touch as it could be a

There are many benefits that using a mattress protector provides for your double mattress. Not only does it protect it from leaks and spills, it also prolongs the life of the mattress. Mattress protectors prevent the risk of dust building up in the mattress. Which in turn can cause allergies, bed bugs, and illnesses to arise. In general, mattress protectors are there to keep your mattress hygienic and feeling like new for longer. We highly recommend a mattress protector with a purchase of a double mattress. If for any reason you are unhappy with your mattress, using a protector prevents stains that can potentially void your warranty.
