    My shape / size isn’t on your website, can you still help?

    Absolutely, we can make our mattresses to ANY shape or size. If you can’t find your shape or size, simply send a drawing to and we’ll get a quote sent back to you

    What happens when I upgrade to a firmer feel?

    When you upgrade to our firmer feel, the top layer of your mattress stays exactly the same (so you still get the same great level of pressure relief on top). We’ll simply change the base layer of your mattress to a firmer, more supportive foam which provides improved support meaning you sink into the mattress less

    Weight considerations:
    If you’re between 15 stone – 20 stone (or just prefer a firmer mattress) be sure to upgrade to the firmer feel so you stay properly supported. For those who weigh less than 15 stone, you can opt for either our standard or upgraded option as you prefer

    Do you have showrooms?

    As an online manufacturer / retailer, we don’t have any showrooms which is how we’re able keep our prices are so reasonable. With this in mind, we’ve been extremely careful designing our concise range of mattresses ensuring they’ll provide the best level of comfort to suit a wide range of different sleepers.

    We don’t believe in selling mattresses we wouldn’t sleep on ourselves which is probably why we get such good reviews. To help add some credibility to our expertise you can read 1,021 customer reviews by clicking here

    How long can I leave my mattress vacuum packed and rolled?

    Your new mattress will be sent vacuum packed and rolled for ease of transportation. Your mattress should not be left rolled for any longer than 2 weeks from the date of dispatch from ourselves. Failure to open within 2 weeks causes changes in the integrity of the foam which affects how the different layers of the mattress interact and therefore feel. In addition you could notice the mattress does not return back to the correct size once opened. For these reasons all mattresses should be opened within 2 weeks.

    If you won’t require your mattress until after a future date, we recommend including a note at the checkout requesting this

    How long will it take for my mattress to recover to it’s original size?

    In most cases, your new mattress will regain to 95% of it’s original size within the first 30 minutes of being opened and will take at least 48 hours to recover to it’s final size. We recommend leaving your mattress a minimum of 6 hours before fitting sheets and sleeping on it for the first time
