Frequently Asked Questions

How It Works

What makes the Nrem so special?

Unlike other mattresses Nrem is a unique adjustable mattress designed specifically for chronic pain sufferers to get a better night’s sleep. Nrem’s unique design consists of a 2000 pocket sprung base and 10 interchangeable foam tablets (5 in a single) in soft, medium and firm, which allow you to adjust and bespoke the mattress to suit your individual needs. With Nrem you can tailor your mattress to give you soft comfort for painful areas and firmer support where it’s needed.

I have chronic pain, will the Nrem help?

The Nrem mattress is designed to help all sufferers of chronic pain, including back pain. You can design your very own sleep experience by adjusting the foam tablets inside the mattress to give bespoke comfort and support to suit your specific pain needs.

Who is this suitable for?

The Nrem mattress is ideally suited to anyone who suffers with any form of pain or chronic pain and struggles to get comfortable at night. With over 94% of our existing customers feeling a significant improvement in the quality of their sleep, the Nrem is designed not only for pain sufferers, but anyone looking to get a better night’s sleep.

Is this suitable for my partner who does not suffer with pain?

Even if you do not suffer with chronic pain the Nrem can help you to get a better night’s sleep. The unique design allows you to customise the comfort of the mattress by adjusting the foam tablets inside, offering better spinal alignment compared to other conventional mattresses. If your partner prefers one comfort level, we can provide additional foam tablets in the desired density to fill that side of the bed.

How does the tablet system work?

Inside the mattress is 10 individual foam tablets (5 in a single) in soft, medium and firm densities. These tablets are easily accessed by unzipping and folding back the top cover. Each tablet can be easily removed and adjusted into your desired position. This allows you to customise the mattress to be as soft or supportive as you need, depending on your individual pain needs.

How will I know what combination of tablets to have?

With Nrem's clever design it is really easy to adjust the mattress and try the different combination of tablets. We recommend that to begin with you lie on your mattress in your normal sleeping position and then work out what tablets will work best for you in each area. If you are stuck we do have some recommended set ups on our website ( or you can contact us directly and we will be happy to help.

Can I buy extra foam tablets?

Certainly. We want you to find the perfect set-up to suit your individual needs. During your first 100 nights, we can provide additional foam tablets to you free of charge. After this, you can purchase any additional tablets you require for a small fee. Simply get in touch and we can arrange this for you.

Does it work for side sleepers?

One of the stand out features of the Nrem mattress is the 5 zone tablet system. This feature allows people who suffer with chronic pain issues to sleep on their side comfortably and works better than your general orthopaedic mattress. Not only is it suitable for side sleepers but also offers great comfort and support for back and stomach sleepers.

Is the mattress anti-dust mite?

Unlike other conventional mattresses Nrem is perfect for those looking for a hygienic and allergy friendly mattress. With it’s unique design our mattress allows you to easily unzip the cover for washing and remove the individual foam tablets. These too can be washed and the inside of the mattress can be vacuumed and cleaned to help combat and remove dust mites and other unwanted bed bugs.

How It's Made

What is the Nrem made of?

Designed exclusively for chronic pain suffers the Nrem mattress has been engineered to give you the best night’s sleep without compromising on comfort or quality. Inside the mattress is a 2000 pocket sprung base and our unique, triple density reflex foam tablet support system. This is topped with a thermo regulating Viscoool foam layer for extra comfort and coolness. The mattress is finally encased in our luxury, cover which can be removed and machine washed for easy cleaning.

What is reflex foam? How is it different from memory foam?

We use reflex foam in our mattress as opposed to traditional memory foam. Reflex foam is different in two main ways. It’s much more responsive to your body meaning it adjusts instantly when you change position during the night and bounces back to its original shape faster. Reflex foam doesn’t get as warm as memory foam so it can keep you cooler at night.

How does the Viscoool layer regulate temperature?

We understand that many chronic pain sufferers find themselves waking during the night as a result of overheating or night sweats. Being too hot makes it difficult to get a good night’s sleep, that’s why we’ve incorporated Viscoool’s thermo regulating foam in to our mattress.

Made from a blend of natural materials including soybean oil and a natural balm, Viscoool foam has a unique open pored structure that helps to reduce heat build-up and allows air to circulate freely within the mattress. This allows you to stay cooler for longer so you can sleep comfortably all night long.

Does your mattress contain latex?

Our mattress is completely latex free which makes it perfect for those that suffer from latex allergies.

Who manufactures the Nrem?

Based in North Manchester, Breasley have been producing quality mattresses for over 40 years with state of the art machinery and a skilled workforce with years of experience in the industry.

The few returns we do receive are either donated to charity or broken down and the components recycled individually for future use in other industries.

How is it tested?
