Should I buy a Tweak Mattress?

Tweak’s mattress is incredibly innovative. The options to customise it means that you can change the foam inserts to suit your sleeping requirements and provide the support you need.

The mattress offers great support and is particularly good for back and side sleepers. Motion transfer is also minimal, making this mattress a great choice for couples.

Over time, some customers do report that the Tweak mattress is prone to sagging. However, with the replaceable inserts you can usually rectify this problem without having to shoulder the cost of a brand new mattress. However, it should also be noted that some people who are prone to back pain find that the Tweak exacerbates the problem and makes back pain worse.

This mattress is a great choice if you find that most mattresses in a box don’t allow you the option to customise a mattress to your exact requirements.

T3 praised the Tweak mattress, saying: The Tweak Slumber mattress is flexible, comfortable and phenomenally supportive: our sleep improved immediately. The customisable design really works, making it a good choice for anyone with back or neck pain – and we love that you can choose a different firmness setup to your partner. Co-sleeping and back ache have never had it so good.

T3 Magazine

The Independent rated the Tweak as one of the best mattresses on the market: Our tester had been at his wit’s end with backache, despite having tried other expensive mattresses that promised to work wonders.With the Tweak, he reported that the support is phenomenal, with no need to compromise on comfort. And if your partner does have restless night, you won’t feel a thing.

The Independent

My sleeping time has improved a lot. I used to wake up a few times during the night but now most of the time I do sleep through. Highly recommended. (January 2020)

The mattress is so versatile it should suit anyone with problems with their joints or pain. (December 2019)

Tweak Customer

Really impressed - adjust each side of the mattress to whatever suits our requirements. Literally just moving foam inserts to wherever needs support. I’d been struggling with a bad back for a couple of months (combination of old mattress, new puppy!) - super comfortable, no more aches. Exactly what I needed. (August 2019)

Tweak Customer

The Tweak mattress is very comfortable, so much so that I don't want to get out of bed in the morning. My morning back stiffness is almost gone now so I feel much more rested & comfortable first thing in the morning. Delivery arrangements & customer service have been excellent. I would definitely recommend this mattress. (June 2019)

Tweak Customer

I love the flexibility of the set up of the bed. I suffer with back problems due to the wrong sort of beds. With this bed I turnover less frequently, spend less time awake during the night, and wake up with less back pain. Another feature of the bed design is that less movement is transmitted from one side of the mattress to the other. When sitting or moving on our last mattress my partner would feel every movement and vibration so if I (or she) were restless it would also tend to disturb the other person. I am very happy with our new mattress and am hoping that the memory foam element will continue to provide the same level of comfort for many years! A worthy investment! (March 2019)

Tweak Customer

Fantastic mattress. Very comfortable and the best sleep we've had for years. I love the fact we can change foam inserts to suit my partner and myself differently. My back pain has been almost non-existent since having this, which was the main reason for purchase. Very happy. (February 2019)
