About Tweak Slumber

Founded with one simple aim - giving everybody their best night’s sleep. Tweak Slumber have created the World’s First Customisable Mattresses. Designed to fit every body, without compromise, they are the only truly bespoke mattresses on the market.

Launched in 2014 by a team of passionate sleep enthusiasts, Tweak Slumber have helped to improve over 2 million nights of sleep. After recently expanding, we now have 2 unique customisable mattress designs: DUO and Nrem.


Designed exclusively for couples who don’t want the same when it comes to mattresses. Each sleeper can customise their side of the bed to their own personal choice of comfort.

Resting upon a supportive core of 1000 pocket springs is a ‘split-comfort’ foam layer. This layer will be customised to each sleepers’ personal firmness preference on their side of the bed. There’s also a cooling foam layer which provides air flow and temperature regulation. The mattress is seamlessly split, so there’s no ridge or uncomfortable zips in the middle.

Prices start from just £795. All DUO mattresses are made to order, giving a truly bespoke sleeping experience.

Customers can ‘Tweak’ the DUO free of charge during the 100 night trial period, making the mattress softer or firmer to get the comfort just right on both sides.


Designed for those who struggle to sleep due to aches and pains, Nrem is the only mattress that gives different levels of comfort and support for different parts of the body.

Using different densities of deep foam inserts in firm, medium and soft, sleepers can customise all 5 zones of the mattress to provide soft comfort for painful areas and support where needed to maintain good posture and spinal alignment.

The Nrem can be customised at any time by simply unzipping and rearranging the foam inserts. Both sides of the mattress work independently, so each person can have their own, unique sleep set up for their best night’s sleep.

With a 40mm cooling comfort layer and added temperature control, individual pocket springs for added comfort and bounce and a natural hypo-allergenic cover aiding a refreshing night’s sleep, it’s clear why 94% of customers have reported an improvement in their sleep after the first night with Nrem!

Prices start from just £595.

Both the DUO and Nrem mattresses are available to buy online at with a large audience network and unique offering like no other on the market.
