    Custom Size Mattresses

    If you have an antique bed frame or a custom made bed, you may find that it is outside the normal dimensions of a super king (6'0" x 6'6" / 180cm x 200cm). If you need an unusual size or shape mattress, use our custom mattress builder for a bespoke order to your measurements and preferred firmness.  

    Super King Beds

    Whether you’re looking for a bed frame or divan base, we have the perfect compliment to your new mattress. We also offer a whole range of divan sets if you would like to buy your bed and mattress all together.
