The Split Mattress for Couples

We’ve reinvented the mattress so you can sleep like never before on a unique hybrid of 5 comfort changing zones, up to 2000 pocket springs and an added temperature regulating foam for your most refreshing sleep yet.

Simply unzip the mattress cover to reveal 5 foam inserts in super soft, medium and firm densities. Rearrange these inserts for soft comfort and firm support that’s tailored to you.

Each side of the mattress can be set up differently, so whatever your sleeping needs, the Tweak fits you.


Our friendly 2 man team will deliver your new Tweak mattress straight to your bedroom within 3 working days, completely FREE of charge to UK Mainland*. We’ll even take away the packaging.

After you place your order, you’ll be contacted to arrange a convenient delivery date and time. We can even take away your old mattress, just make sure to let us know when placing your order if you’d like to use this service.

*Please note that there will be an extra charge for delivery to the Highlands, Islands and N. Ireland. Your delivery will be calculated at checkout.

Sleep Trial

We’re sure you will love your new mattress but if it’s not quite right, please let us know. We will help you to ‘tweak’ your mattress to find a perfect setup that suits your needs.

We ask that you sleep on the mattress for at least 30 days to give your body time to adjust. If the Tweak isn’t right for you after this time, we’ll come and collect it. Please refer to our full returns policy for more information.
