Memory foam mattresses can be a good solution to a plethora of problems, including aching lower back and overall reduced sleep quality. But how do you choose a quality product that fits the bill and checks all the boxes? There are so many models on the market – from good quality products from reputable companies to cheap Chinese knock-offs that we wouldn’t recommend to our worst enemy.

It is a tough choice to make!

That is the sole reason we created LightSleeper – to help you choose the mattress that is right for you and you alone, and to help you make that choice along the way. Companies can never pay to feature their products on LightSleeper, nor we are getting paid to recommend one product over the other – we are an independent resource and we only recommend products that have passed our tests and we feel that they are the best in their category.

So without further ado, let’s see what we think are the best memory foam mattresses in the UK today and why.

How to Choose a Memory Foam Mattress?

What types of memory foam mattresses are there?

Nowadays, we are bombarded with new brands and products every day, but not all offer quality products. For you to be able to pick the right one, there are a few features you will need to factor in before making your decision. They are the following:

Sleeping Position

An essential factor to consider when choosing a mattress is the position you sleep in and your sleeping patterns in general. You need to understand that the way you sleep can determine the areas you put the most pressure on. That will help you narrow down the options which will accommodate your needs.

Side sleepers

We want to start with a side sleeper and the fact that they often put pressure on their shoulders and lumbar area. If you’re one of those people, we highly recommend selecting a medium-firm option with pressure points, in the lower back area. Our reason behind it is that you will most likely find it suitable for this position since it’s still flexible to your body’s curvatures.

Back Sleepers

Next, we have people that sleep on their backs. If you are one of them, you’ll probably want a product, that will alleviate pressure points just like a side sleeper. Therefore you should take into consideration a medium-firm product that will provide fantastic spine support. Understand that a back sleeper has to avoid the extra-firm items because they might fail to adjust to the lumbar curve.

Stomach sleepers

In third, we have the side sleepers. Usually, this type puts pressure on their neck and back. That’s why, in this situation, your best option will be a firmer product because it’s excellent for spine support. Also, it will help alleviate neck tension and prevent your lower body from sinking into the mattress. With that, you avoid putting your neck at an inappropriate angle that may bring you discomfort.

Various Sleeping Positions

Lastly, we have the combination of all the types above. People with various sleeping patterns would often prefer a medium mattress with a thick top layer of memory foam. Thus, you should look for high-density products which can help you sleep on all sides comfortably without putting too much pressure on your body.

How to Choose a Memory Foam Mattress?

Density & Firmness

Two of the essential features of a mattress are its firmness and density. Typically they determine the longevity, price, and overall feel of the bed you will be sleeping on. We measure density with mass per unit volume at a given area.

In general high-density foams have extended longevity, compared to low-density ones. However, there is a common misconception that the higher the density, the firmer the bed.

You want to aim for a memory foam product with a high-density and Indentation Force Deflection (IFD) rating. The higher the IFD rating, the better. That indicates the brand used an optimal amount of material in the bedding. People favour high-density options if they suffer from chronic body aches and pain.

Finally, you shouldn’t forget about the different types of memory foam, as they come with different properties and heat activation levels.

Body Type & Weight

Matching your body type to a mattress can confusing because it won’t matter how comfortable it is if you cannot fit on top of it.

That’s why you should think about the dimensions that accommodate your body size and your partner’s if you are sharing the bed. For example, a couple will fit in a queen-sized bed, but they will most likely be more comfortable in a king option. Whereas, a solo sleeper will generally find a full-size as a good enough choice.

The item you select has to be able to accommodate your body weight. If you’re on the heavier side, we recommend looking at our article about Best Mattresses for Heavy People. On average, a person who weighs 60kg will be ell-supported by a medium-density memory foam mattress.


When the memory mattress was first introduced, it was quite a pricey option, but today some brands offer quality products with competitive pricing. Of course, the overall price of a mattress depends on its quality and the manufacturer.

However, most models stay in the diapason between £800 – £1,300. With this price tag, you can receive all the features and benefits you need for a well supported and comfortable night’s sleep.

Trial Period

People can go to a store and lay on a bed for a few minutes, but that doesn’t tell you if the product will be comfortable in the long run and if this memory foam mattress is good for your specific needs and preferences. That’s where the trial period comes in handy. Well-respected brands offer a trial period that can vary between 30-365 days.

Ultimately, this is the best way for you to determine if a mattress is suitable for your personal preferences. Trial periods give you the opportunity to “test drive” an item in order to see if this is the best option for you. That’s why you should always select options that offer it.


Every brand that wants to have a reputable one has to offer a warranty for the products they put out. Most guarantees will range between 5 to 10 years, but some will offer 20, 30 or even a lifetime option. We recommend that you try to aim for the best length possible. If a manufacturer offers a whole decade, this speaks volumes to the mattresses they put on the market.

However, if the warranty is short, this might indicate potential harmful chemicals or low-quality products. If you are worried if a memory foam mattress is good for your health, make sure to check our guide on it.
