Hi Susan,

Thank you for your enquiry.

We have provided a link to the section on our site dealing with mattress sizes and weights, which clarifies the size of super king mattresses either as a one piece or a zip and link set.

From what you say it would appear that the type of base you are looking for is an ottoman base, which we do make in the super king size and it comes in two halves split from top to toe, for ease of access.

Our John Ryan Ottoman bases are perfect for those who need the most storage space from their mattress base. With a front lift construction method, supported by high-quality gas struts, it enables you to lift the entire mattress up and utilise the significant storage space beneath it.

The depth of the ottoman storage is 25cm or 10″. The height if the base is 40cm including castors.Our Ottoman bases are platform top bases. This means they don’t contain springs and are a solid base for the mattress above it. Placing a pocket sprung mattress on top of this base will firm up the overall feel of the mattress slightly.

In order for us to be able to recommend the best product for you from our ranges, please call our office on 0161 437 4419 with details of your body weights, preferred feel and budget.

Kind regards,
Amy.
