The SleepHubs Tweak mattress is a unique hybrid mattress combining pocket springs and pressure-relieving foam.

It’s also a uniquely customisable mattress that features five comfort-changing zones that offer softness for superior comfort or firmness to help relieve back pain.

You can change the setup at any time to suit your individual needs and preferences, and can even customise the two different halves of the bed separately!

The Tweak mattress was previously known as the Nrem Mattress at Tweak Slumber.

Tweak mattresses are made in the UK.

  • Low motion transfer

The SleepHubs Tweak mattress, previously known as the Nrem Mattress at Tweak Slumber, is a unique hybrid of 5 different comfort zones, up to 1000 pocket springs, and temperature-regulating foam.

The five layers in detail:

  • Hypo-allergenic fabric cover that’s soft and breathable
  • 4 cm (1.5") pressure-relieving & cooling comfort layer that wicks away moisture
  • 5 customisable comfort zones with 3 different densities of high resilient polyurethane foam in super soft, medium, and firm densities that can be moved around and fully customised to find your perfect sleep
  • Up to 1000 individually wrapped pocket springs that offer superior support and bounce
  • Resilient base foam that makes up the bottom and sides of the mattress

Unique layer of customisable foam

The most unique feature of the Tweak mattress is the third layer of customisable foam.

These come in super-soft, medium, and firm densities and are made of reflex foam. This foam is superbly comfortable and adapts well to the contours of the body.

It reacts faster than memory foam, making movement easier and avoiding the sinking feeling that’s so common with memory foam mattresses.

You can rearrange these foam inserts to provide optimal support.

You can also set up the two sides of the mattress differently, so it will suit both you and your partner.

Tweak mattress cover

The SleepHubs Tweak mattress comes with a very soft visco-elastic polyester blend cover.

It’s a breathable cover that helps regulate the sleeping climate.

The Tweak mattress cover features a zipper so it can easily be removed and machine-washed at 30 degrees.

This is great for hygienic reasons and also makes the mattress suitable for people prone to allergies.

The cover is also fire resistant.

You’ll find two handles on the sides of the mattress cover, which makes moving the mattress around much easier.

Tweak mattress properties

Comfort and firmness

The Tweak mattress offers just the right amount of comfort and support.

The reactive foam is very supportive, responds well to movement, and adapts perfectly to the contours of the body.

It also bounces back more quickly than standard memory foam, making moving around on the mattress easier.

This is great for restless sleepers or couples.

The SleepHubs Tweak mattress is also great for anyone who suffers from back or neck pain.

It helps relieve pressure adequately and offers you the right level of support to help your muscles relax as you drift into sleep.

The mattress is particularly recommended for back and side sleepers.


A warmer sleep

The Tweak mattress offers a slightly warmer sleep, which is great for anyone who easily feels cold at night.

While the breathable cover and the springs do help regulate the temperature to make it suitable for a wider range of people, it may still be too warm for very heavy sweaters.

Low motion transfer is great for couples

The Tweak mattress is particularly well-suited for couples.

Not only do the customisable foams ensure that you can design each half of the bed to suit each partner, thereby virtually eliminating arguments about preferred mattress firmness, but the Tweak mattress also has no to low motion transfer.

If your partner tosses and turns around at night, you won’t be able to feel the movement.

This makes sharing your bed with a partner all the more comfortable.

How to customise your mattress

The unique feature of the Tweak mattress is that it’s customisable.

The third layer features different inserts in various degrees of firmness, which you can adjust and move around as you wish.

Each side of the mattress can also have its own configuration, so both you and your partner can find a surface feel that’s perfect for you.

As standard, the mattress comes with 3 super soft, 4 medium, and 3 firm foam inserts that can be interchanged across both sides of the bed.

The exact number of inserts will depend on the size of the mattress.

SleepHubs recommends numerous steps to find your perfect configuration:

  1. Contact SleepHubs and try their MattressFit consultation to help you get the recommended sleep setup for your needs.
  2. Unzip the top cover and fold or roll it back to one end of the bed. If it’s easier, you can also simply remove the whole cover.
  3. Roll back the comfort layer to reveal the selection of foam inserts.
  4. Rearrange the foam inserts as you please. Ensure that the corrugated bottom is aligned correctly with the base — if not, the foam inserts may move around while you sleep, which can become uncomfortable.
  5. Put the comfort layer and cover back into place, zip it all up, and relax.

Delivery & customer service

SleepHubs provides a white-glove delivery service that takes your mattress directly to your bedroom and even removes the packaging — at no additional charge.

The mattress is delivered vacuum-packed and tightly rolled — but not in a box.

The mattress is light enough to be handled by one person but SleepHubs recommends two people to avoid injury, especially if you’re choosing this mattress due to chronic back pain.

Unique delivery options

Delivery is free of charge to mainland UK.

Deliveries are usually made within 10 working days.

After ordering, you’ll be contacted within 7 days to arrange the best delivery date and time.

SleepHubs can also remove your old mattress for you — simply select this option when placing your order.



Not everyone will encounter off-gassing.

But, if you do, there’s no need to worry.

That slight chemical smell you encounter when first unpacking your Tweak mattress is completely normal and merely a result of the manufacturing process.

Simply ventilate your room as your mattress expands to reach its full size and the smell will quickly disappear.

It’s also not harmful or toxic in any way.

Risk-free trial period

The SleepHubs Tweak mattress comes with a risk-free 100-night trial period.

This allows you to try out the mattress for 100 nights, giving you the chance to really see if it’s perfect for you.

SleepHubs recommends that you try the mattress for at least 30 days to give your body time to adjust. After all, it can take a little while for you to get used to a new mattress.

And if you’re not 100% convinced, then you can simply send it back and receive a full refund.


The Tweak mattress is an excellent choice for people who struggle with chronic back or neck pain and for couples trying to reach a compromise on the ideal level of firmness.

With interchangeable layers in various degrees of firmness, this customisable mattress offers more choice and opportunity than other mattresses.
