How is the Tweak mattress constructed?

Tweak Duo Mattress Review

The Tweak mattress has a unique 4-layer design (+ cover) that can be customised to suit every individual sleeper’s needs. This product is made locally here in the UK and meet all health and safety requirements.

Tweak is delivered with a combination of interchangeable foam inserts that you can rearrange by yourself as many times as you want to get the best night’s sleep. These foams have been assessed by both EUROPUR and SPSC (Sleep Products Safety Council). Also, Sleep Hubs is a certified FIRA Gold member.

What is in Tweak’s layers?

Layers & Construction

The Tweak Slumber mattress is constructed from four unique layers of hybrid innovation. First, we have the pressure relieving, cooling comfort layer that is 4cm deep. It has an open-cell structure that wicks away moisture and keeps you cool at night.

Next, we have the customisable comfort zones layer with three different densities (soft, medium and firm) of highly resilient Polyurethane foam that will provide you with the comfort and support you need in all the right places.

The mattresses’ third layer is the 1,000 full-size pocket springs for superior support and bounce. They are individually wrapped and move independently as you sleep, which means your partner (if you have one) won’t be disturbed by your tossing and turning. These springs are 10cm high and have a gauge of 1.5mm.

Lastly, we have the highly resilient base foam encapsulating the springs for edge to edge support. We have the springs encapsulated in the high-density foam making up the base and the mattress walls. It’s covered in a medium-density reflex foam, ensuring you can feel the bounce of the springs below.

How thick is it?

The total thickness of the Sleep Hubs Tweak mattress is 25cm, meaning your regular sheets and bedding would fit without an issue. This product can be used on any bed base and even the floor. It can also hold up to 16 stone or 101 kg per side(two people per bed).

How firm is it?

Firmness & thickness

This mattress from Sleep Hubs can vary on the firmness scale because the brand doesn’t believe in the stereotype of one size fits all, when it comes down to the level of comfort. That’s why they’ve designed a product with adjustable firmness level due to the foam inserts in super soft, medium and firm densities. Generally speaking, the foams are between 5,5 – 7,5 out of 10 (one being the softest and ten the firmest).

What about the Tweak cover?

Cover & Fabrics

The brand has come up with a visco-elastic polyester blend cover that provides a soft and breathable sleeping surface. It’s also hypoallergenic, fire-resistant and offers temperature control. The cover itself is easily removable and can be machine washed at 30 degrees. You can also air dry it so that your bed is always fresh and clean. The mattress cover includes two handles on each side (eight in total) for easy manoeuvring.


The Tweak has a unique, modular design encased in a white and grey cover with a blue lining. This design allows you to choose where you want soft comfort and firm support across your body since each side of the mattress has its’ own configuration.

The purchase will contain three super-soft, four medium and three firm foam inserts that can be interchanged across both sides of the bed. This option has a neutral colour mix which can work in nearly every room setting.

How long is the free trial period?

All Tweak mattresses have a 100-night trial period in which you get to try your purchase in the comfort of your home and give your body time to adjust. Laying on a bed in a store for ten minutes can’t be enough for you to decide since, typically, your body will need between 4 to 6 weeks to adjust to a new mattress.

If, for some reason, you’re aren’t satisfied with your purchase, you can return it and get a full refund at no cost to you.  

How long is the warranty?


All Tweak mattresses are covered under a 10-year warranty. You don’t have to register your guarantee. It will automatically become active from the date of delivery of your new mattress. Your mattress is protected against faulty workmanship and materials.

However, the company reserves the right not to honour claims under this guarantee at their discretion. Let’s talk about the situations in which it applies and when it doesn’t:

  • Visible dipping or sagging greater than 3cm that has not resulted due to normal body impressions or improper use as per our care instructions below

What sizes does Tweak come in?


The company wants you to find your perfect match with one of their four available size options. SleepHubs has tried to simplify that by concentrating on nine sizes to create a straightforward, no-nonsense guide with which you won’t be overwhelmed or confused.

  • Single – 90 x 190 cm
  • Double – 135 × 190 cm
  • King – 150 × 200 cm

This is one of the few mattresses that doesn’t come in a box. Instead, it’s vacuum-sealed and delivered wrapped in protective green plastic. The delivery company is very professional, which is why they will take the mattress to your room of choice and set it up. They even offer old mattress removal at an additional fee.
