Customise to suit you

Side sleepers and back sleepers need comfort and support in different places which a standard mattress does not offer. The Tweak mattress can be customised to suit every individual sleeper – that’s what makes us different.

Tweak is delivered with a combination of interchangeable foam inserts which you can rearrange yourself as often as you need to get your best night’s sleep.

What's Inside Tweak?

The Tweak mattress measures 25cm deep and can be used on any bed base including the floor. Click each point below for an overview of the layers inside the mattress.

Our visco-elastic polyester blend cover provides a breathable sleeping surface. It’s fire resistant and provides temperature control, plus it’s hypo-allergenic making it ideal for those with dust or skin allergies. The zippable cover can be machine washed at 30 degrees and air dried, keeping your mattress fresher for longer.
This 4cm deep comfort layer contours and cushions the body for a greater level of comfort. The open cell structure wicks away moisture and keeps you cooler for longer.
We use highly resilient Polyurethane foam in super soft, medium and firm densities so you can get comfort and support in all the right places. This foam bounces back quicker than standard memory foam so you can turn over without feeling stuck. Our 5 comfort zones can be changed at any time so you can get your best night’s sleep.
1,000 full size pocket springs make up the mattress core. They’re individually wrapped and move independently as you sleep, so you won’t be disturbed by your partner's tossing and turning during the night. Our springs measure 10cm high and have a gauge of 1.5mm.
The springs are encapsulated in a high density, supportive foam that makes up the base and the mattress walls. They’re then covered in a medium density reflex foam that ensures you can feel the bounce of the springs below.

Tailored to You

Tweak mattress inserts

The Tweak has a unique, modular design which means you can decide where you want soft comfort and firm support across your body.

Each side of the mattress has its’ own configuration, so there’s no need to compromise with your partner over which zones should be soft and which are firm!

As standard, the mattress will contain 3 super soft, 4 medium and 3 firm foam inserts which can be interchanged across both sides of the bed.

  1. Contact the SleepHubs experts for your recommended sleep setup, or create your own!
  2. Unzip the top cover and fold/roll back to one end of the bed (you can take it off altogether if this is easier).
  3. Roll back the cooling comfort layer to meet the cover and reveal the selection of foam inserts inside.
  4. Rearrange the foam inserts, ensuring the corrugated bottom is aligned correctly onto the base. (see image below) – if the inserts are not slotted in correctly, they may move and become uncomfortable.
  5. Roll back the cooling comfort layer and cover, zip up and enjoy!
