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 mattress over a soft one? According to many publications sleeping on a firm 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 firm 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.

How to choose the best 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.

how to choose the best firm mattress

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.

What are the benefits of a firm mattress?

Most people that have migrated to a firm mattress can usually offer a long list of reasons why. Even some chiropractors, doctors and other medical professionals find spending seven or eight hours a night resting on a firm bed beneficial.

Support

You will receive superior support thanks to the sturdy feel with the set mattress firmness. Edge support tests aren’t necessary here because of the solid surface on which you can sprawl out across with having the feeling of roll-off.

Spine Alignment

These types of mattresses allow more pushback to support the entire length of your body, helping keep the natural curves of your spine in alignment, while preventing you from sinking into the bed. You might get unmatched pressure relief and aid in relieving back pain by maintaining a neutral spine position.

Weight Distribution

You don’t have to worry about sinking in too far into your bed with this mattress type since it will keep your body elevated on the surface with ease. Your weight will be more evenly distributed, making this the ideal mattress firmness for heavier people.

Motion Isolation

Harder textures usually respond to less movement. Therefore a firmer option will reduce the amount of motion transfer that makes its way over to your side of the bed, making it perfect for sharing with a partner.

Who is a firm mattress best for?

Who is a firm mattress best for?

Every type has its pros and cons, but firmer beds can be incredibly beneficial for some individuals. They are the following:

Back & Stomach Sleepers

People in both sleeping positions will benefit from a firmer product. Back sleepers typically need a bed that will help keep their spine aligned with their natural curves. In contrast, front sleepers need enough support to prevent their stomach from sinking too far and pulling the spine into an unnatural shape.

You can finally enjoy nights of pain-free rest since you will get the needed support for the entire length of the body.

People with Back Pain

In general, more than half of the worlds population has suffered or experienced lower back pain at some point throughout their lives. And if you’re one of those people, know that a firmer product might be the solution to your problems.

Professionals have discussed that a firm mattress can significantly improve sleep quality and stress levels, helping reduce back pain.

How can I make a mattress firmer?

If your bed is still in good working condition, but you don’t find it supportive enough, you can always make it firmer by using a mattress topper.

Look for ones that are firm and thick enough to change the comfort feel noticeable. However, if your mattress is wearing out or sagging, even the most expensive mattress topper might not help you. If you find yourself in this situation, consider getting a new one instead.

Can a mattress be too firm?

Can a mattress be too firm?

Since firmness is a personal preference, yes you can find a mattress to be too firm. Most people don’t want to feel like they’re sleeping on concrete.

As we’ve already mentioned, people are different, and so are their needs. Therefore, for some people, a firm mattress can’t accommodate pressure points. In that case, we will also recommend a mattress topper, but this time to soften the surface.

Do firm mattresses last longer?

Many people ask that question. However, a firmer bed won’t necessarily last longer than a soft one. The longevity of a product is usually the most dependent on the materials it’s crafted from.

All materials will start to wear out in time, meaning that even a sturdy option will soften over time. If you want to find a bed that will last longer consider factors like design and quality of materials, they have the most significant impact on an item’s durability.

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 firm mattress on the market.
