Best Double Mattress


As recently as 2015, a panel of experts from the National Sleep Foundation of the UK updated their recommended sleep durations for healthy adults. Basing themselves on a thorough, systematic revie...w of the world’s scientific data about sleep duration and health, the NSF determined that an adult individual should get anywhere between 7 to 9 hours of full sleep per night. If we do some simple math, we will quickly discover that a healthy adult should be spending anywhere from 2,550 to 3,285 total hours of sleep per year! That is a considerable amount of hours we spend on a double mattress. Therefore; if our physical, mental, and emotional well-being is directly connected to sound sleep, wouldn’t it behoove us to do everything in our power to ensure we sleep on a quality mattress?

What do i need to know when buying the best double bed mattress?

We have already established that the quality of the mattress we sleep on has a tangible effect on our quality of life, as well as our ability to tackle daily challenges. Let us now decide if perhaps it is time you purchase a new best double mattress UK size. This is important considering that the decision to buy the best double mattress is not just a monetary investment; it is also a potentially life-altering choice.

The average practical lifetime of a modern best double mattress is lying somewhere around the 10-year mark. Depending on the make and build quality, some units will last 13 to 15 years, and some, on the lower end, will only last around 8. However, if you find that the quality of your sleep has gradually deteriorated over the past years, you wake up tired, and with stiff and achy limbs, it is time to buy a new mattress.

Where do I start?

Buying a brand new mattress for double bed is an exciting prospect, but it can also be a daunting task with so many options available. Often it is not easy to find a mattress that fits all your needs, which is why it is essential to become as educated as possible in the in`s and out`s of mattresses so that you make a better and more informed choice. Surprisingly, the majority of people spend more time and energy deciding on unnecessary stuff than they do decide on their next mattress. Do not make this costly mistake.

First, let us discuss some important factors you would do well to consider before committing to buying a double mattress size. A new mattress for double bed should be comfortable from the get-go. As soon as you lie down on a new mattress for double bed, you should feel at ease and relaxed. A mattress that is initially, too soft or too hard for your taste, is not the right mattress for you. This can potentially be the most crucial factor to consider when hunting for a new mattress. A quality 4ft6 double bed mattress will apply an upward force to “push” you up and counteract the downward force being exerted by the weight of your body. Whether you sleep on your side, lying face down, or on your back, the right mattress should be able to support all the curves and angles of your body, fully. A 4ft6 mattress that is too hard or firm would cause your hips and shoulders to rise disproportionately from your spine, and this would lead to aches and pains. A 4ft6 double mattress that is too soft will have a similar effect, and by not offering sufficient support, your body will misalign, and discomfort will develop.

Another significant factor to consider and one that is often overlooked is the mattresses’ ability to suppress the transfer of movement. Some mattresses are more likely to transfer motion across the surface and thus more likely to disturb your rest time.

What about the size?

This, of course, will be highly dependent on various factors such as the size of the room your new double mattress will be placed in, the body size of each individual, and any budgetary constraints that are present. There are many sizes available, and most of the time, each country will have dimensions that are slight variations of the standard models. I recommend that you choose a bed that is at least 5 inches longer than you and your partner height, as well as wide enough so that you can sleep comfortably without disturbing one another.

The next thing you must consider is the type of mattress that will best suit your preferences. In-depth knowledge is the best tool you can use to your aid before making this decision. Generally speaking, there are two main categories of mattresses available.

These are Spring Mattresses and Memory Foam Mattresses:

Pocket Sprung

Spring system mattresses are the most common type, and they are characterized by rows of metal springs embedded between layers of foam sheets and other fillers. Regularly, these are the least expensive option and can last anywhere from 5 to 15 years.

Memory Foam

Memory foam was developed by NASA and consequently revolutionized various industries such as the textile, automotive, construction, leisure, and bedding sectors. Memory Foam has state of the art properties that allow it to excel at alleviating the pressures encountered by astronauts’ bodies as they take off into space. Imagine what it can do for your body as you rest at night. This type of synthetic material was initially developed in the 60s, although it wasn’t until the early 90’s that researchers managed to incorporate it into domestic life. Memory Foam found popularity in hospitals across the world because it produces very little pressure on lying down bodies. Memory Foam is also used in clinical products such as prostheses and adaptable mattresses for people with lumbar or cervical ailments, with inflamed or burned body parts, or for people who spend a lot of time bedridden.

Memory Foam’s primary characteristic is that it offers a material with a medium firmness combined with exceptional adaptability. It is one of the best options when choosing to buy a new mattress. The advantage of Memory Foam is that it adapts to the body but without generating the feeling of sinking into the surface. Depending on the model and make of the mattress, it may have different Memory Foam configurations and layers. The density of the viscoelastic material is translated into the amount of material it contains per cubic meter (Kg / m3). Depending on the density of the Memory Foam used for the manufacture of mattresses, they will offer various benefits or others. It could be said that the higher the density, the greater the sensation of support, and the greater degree of adaptability; therefore, the higher the benefits in comfort and durability. Memory foam mattresses are made of high-density polyurethane foams. Memory Foam mattresses are usually a more expensive option; however, they provide exceptional body support.

Other Materials

Across the world, you will find other options in mattress manufacture. Viscoelastic mattresses are highly popular; these are made from a slow reaction gel/foam mixture that tends to be on the softer side of the spectrum. Latex mattresses are another standard offering. Latex mattresses tend to be more rigid and durable than those made of viscoelastic. The downside to latex builds is that they are not particularly good at preventing the transfer of movement. Now that you know a little more about mattresses and the importance of choosing the right one, you are better prepared to make an informed choice. Remember that making the best decision today will have the best long term effects down the road. Now, let’s take a look at some of the best 4ft6 double mattress reviews in the UK!
