Nrem Mattress

What makes the Nrem special?

Nrem is a unique, customisable mattress, designed for a better, pain free night's sleep. The unique design consists of a 1000 pocket sprung base and 10 interchangeable foam inserts (5 in a single) in super soft, soft, medium and firm, which allow you to adjust each zone to suit your individual needs. You can tailor your mattress to give you soft comfort for painful areas and firmer support where it’s needed. You can even purchase extra firm inserts if you need to. 

I suffer from 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 inserts inside the mattress to give bespoke comfort and support to suit your specific pain needs. Whilst the mattress can not cure chronic pain conditions, it can help you to get more comfortable at night, giving you a better night's sleep.

I don't suffer with chronic pain, can I still use the Nrem?

The Nrem is designed not only for pain sufferers, but anyone looking to get a better night’s sleep. 94% of customers feel a significant improvement in the quality of their sleep after just 1 night. The 5 customisable zones mean you can tailor your mattress exactly to your body - this helps to align the spine and maintain good posture, preventing aches and pains in the morning. 

How does the comfort changing system work?

The Nrem is divided in to 5 zones for each sleeper. Inside the mattress you'll find 10 foam inserts (5 in a single) in super soft, soft, medium and firm densities.

The inserts can be interchanged across each 'zone' allowing you to have softer comfort or firmer support for each area of your body. Typically, people place the softer inserts beneath the hips and shoulders, with a firmer insert beneath the back - but it's completely down to personal preference!

Is the Nrem good for side sleepers?

The comfort changing system means that the Nrem is suited to any sleeping position. Simply adjust your foam inserts until you feel comfortable. 

How do I decide where to place the foam inserts?

The Nrem will be delivered with the foam inserts arranged in our 'Lower Back Pain Setup'. This is the most common setup that our customers choose and generally, it has a soft feel to it. 

We recommend you try this setup to begin with, but if it's not comfortable, it's really simple to change the setup at any time. 

If you have pain in a particular area, you may need a softer insert there, but this also depends on your personal preference and the position you sleep in. Back sleepers typically opt for a slightly firmer feel whereas side sleepers prefer something softer.

We are always on hand to give advice and help you to find the setup that's best for you. Please telephone 0333 003 3352 or email info@tweakslumber.com to discuss your personal needs. 

Can I get additional foam inserts?

Absolutely! If you need to replace any inserts or if you need any extra to find your ideal setup, you can purchase them for a small charge. We have 5 densities available: Super soft, soft, medium, firm and extra firm.

DUO Mattress

What makes the DUO special?

DUO allows couples to select their own comfort level for their side of the bed. It's seamlessly split down the middle so you won't feel any uncomfortable ridges or zips.

You can choose between super soft, medium and firm for each side. You can even swap your firmness with the pull of a zip, so if your preferences change, your mattress does too. Additional inserts are available to purchase in super soft, soft, medium, firm and even extra firm. 

DUO is not one size fits all, it’s the one that fits right.

I have back pain, will the DUO help?

If you wake up with aches and pains, you may benefit from a firmer, supportive mattress. You can choose firm for your side of the mattress, whilst your partner can opt for a softer comfort if they prefer.

If your pain is chronic, you may be better suited to the Nrem mattress which is made up of 5 interchangeable comfort zones. 

Who is the DUO mattress suitable for?

Nobody should compromise on their comfort. The DUO mattress is perfect for couples who are different sizes or have different preferences on comfort. Some people like to sink in to a cocoon-like soft mattress whereas others prefer to lie on top of a mattress with no give. The DUO gives the best of both worlds, without the need for a zip and link style mattress.

Can I change my comfort level in the future?

Of course! You can tweak your comfort level at any time. 

Additional foam inserts in your chosen density are available here https://tweakslumber.com/products/replacement-duo-foam-inserts

General

Are Tweak mattresses suitable for allergy sufferers?

The high quality, breathable materials we use makes our mattresses dust-mite and bedbug resistant. 

Tweak mattresses are also suitable for those with sensitive skin.

The cover can be removed and machine washed, whilst the individual components within the mattress can also be removed for cleaning - helping you to keep your mattress fresh for years to come. 

What are Tweak mattresses made of?

Both the Nrem and DUO mattresses have been engineered to give you the best night's sleep, without compromising on comfort. 

Inside each mattress you'll find 1,000 full size, individually wrapped pocket springs and our unique, comfort changing foam layer. This is topped with a supersoft thermo regulating foam layer for extra comfort and coolness.

The foam we use is an open pored, high density Polyurethane foam which is more resilient and more breathable than traditional memory foam.

The mattress is finally encased in our luxury, hypoallergenic cover which can be removed and machine washed for easy cleaning.

Do you use memory foam in Tweak mattresses?

Traditional memory foam reacts and moulds to the body when heat is applied. Sleepers tend to sink in to their mattress, compressing the foam and stopping air from flowing and escaping. Memory foam takes a while to return to its original shape making it difficult for some sleepers to turn over as well as being too warm for some.

We use a high density Polyurethane foam which has an open cell structure different to memory foam. The larger air pockets mean the foam reacts to pressure and not heat. The structure of the foam means heat can escape, and air can flow freely, so you won't overheat, nor will you struggle to turn over in bed. 

Do your mattresses contain any latex?

No. All Tweak mattresses are completely latex free.

Who manufactures Tweak mattresses?

As your mattress is vacuum packed, it needs to expand before you can sleep on it. This usually takes 3-4 hours but it’s best to allow it to breathe for up to 6 hours before making the bed. Opening a window, unzipping the cover and folding back to reveal the foam inserts will help to dissipate any odour.
