We all hate waking up all stiff and achy from sleeping on the wrong kind of mattress. But do you know that most doctors and sleep specialists are more inclined to recommend a firm bed over a soft one? According to many publications sleeping on a harder mattress can help your back feel better, they provide better support and are usually more forgiving towards heavier built people.

But what is the best mattress for your needs? There are so many options on the market, all claiming to be the best thing since sliced bread. But is that claim true? Who to trust and who to avoid?

That’s why we created LightSleeper – to help you choose the product that is right for you and you alone, and 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 let’s see what we think are the best firm mattresses in the UK today and why.

After that, we have the ‘Wave technology’ support layer, which has added depth and density. Another round of springs follow, but this time they are 1,000 135mm pocket springs, followed by a support base for structure and solidity. And finally, the non-slip base ensures that your mattress stays put, while you rest.

Overall, the Brook and Wilde Elite is ergonomically engineered to provide improved support, so you’ll wake up free of aches and pains. This product can be purchased in four sizes: single, double, king and super king with a depth of 28cm, and if firm isn’t enough, you can get the extra-firm option.

How to choose a firm mattress?

Shopping for a new bed can be challenging and overwhelming since most mattress companies say they are the best. However, they can’t all be! When you’re making a choice, there are some essential considerations that you have to focus on to find yourself satisfied with the set purchase. They are the following:

Type & Materials

The type of mattress and the materials it’s made from are the most crucial features driving its performance and durability. Most people choose memory foam, latex, innerspring or hybrid beds. However, after you decide the type, you have to check the quality of materials its constructed from.

Each type and material have their pros and cons, and it’s up to you to decide what your personal preference is.

Pressure Relief

Some people worry that a firm mattress can’t provide pressure relief, but that’s not true. It can still offer sufficient cushioning of your pressure points if you know what to look for. Remember that your choice depends not only on preference but also on body weight and sleeping position.

Ensure you select a product that can tailor to your weight and provide you with proper spinal alignment.

Motion Isolation

Motion isolation is essential if you share the bed with a partner since it can significantly reduce the chances of you waking up from movement on another side.

Typically firm options with less contouring, transfer more motion. Keep in mind that interior materials can significantly affect the disturbance you’re likely to experience. Therefore, select a product with good isolation properties.

Temperature Regulation

Some mattresses tend to retain heat more than others, meaning you can wake up overheated and in sweat. If you consider yourself a hot sleeper, look for breathable items that offer a good airflow throughout.

Memory foam moulds to your body, which may keep you warmer, so if you want to buy a foam product, choose one with a cooling gel of some sort or a cooling system. Pocket sprung mattresses and hybrids are usually the most breathable suggestions.

Edge Support

If you’re searching for a solid bed, you want it to have that same feel across the entire surface. This way, you can effectively use the whole bed while making it easier to sit on the edge without the mattress sagging.

Ease of Movement

If you’re someone that switches sleeping positions during the night or engages in intimate activities, you’ll want a bed that makes it easier to move around the surface. Your best two options will be latex and hybrid mattresses since they typically have more bounce to facilitate movement.

Price

Understand that if you want your mattress to promote quality sleep, you should select a high-quality product, which sometimes can mean investing more than you anticipated.

Often cheap mattresses mean you’ll have to spend extra money on related accessories such as a new bed frame, mattress topper, or pillows to improve your sleeping experience, which may cost your more in the long run.

Trial Period & Warranty

You won’t be able to tell if a bed is right for you, only from laying on it for ten minutes in the store, which is why we recommend you look for choices that offer a free trial period at home. We recommend you choose one with a minimum of 30 days so that your body has time to adjust.

Often the lifespan of a mattress can also hint at its quality. Most warranties vary from 1 to 10 years, but a few brands offer a lifetime guarantee. However, make sure to read the fine print to know how the return process works.

Return Policy

Last but surely not least, we suggest you read the return policy before making a purchase. Different brands have different return policies. Some will give you your money back, others will offer an exchange, and third may deny your return depending on the situation.

Final Words

Whether a mattress is right for you largely depends on your personal firmness preferences. However, firmer products can be beneficial for many, if you know how to select one. No matter your choice make sure your purchase comes with a solid in-home trial period to ensure the firmness is really what you’re looking for.

Mattress brands frequently change, and so do the products they offer, which is why we will continue to provide you with the most up to par information and try to shed some light on the best mattress on the market.

We might not be professionals, but we’ve tested, researched and commented on every product we’ve put on this list. With that said, we hope that this article was helpful, and you were able to find what you are looking for.
