Hi Valerie,

Thank you for your question.

The fall to the middle that you refer to may have been as a result of your slatted base having a central spine, which is lower than the slats either side (if a sprung slatted base).   In this instance, you have made the base more solid by adding the MDF over the central area bridging that dipped area below the mattress.This should have sorted the problem out for you.

However a true pocket sprung mattress should enable both parties to move independently without disturbing each other. The movement you refer to may be as a result of the frame you have not being sturdy enough.  A medium feel mattress combined with the central MDF may resolve the issue, and if you find this too firm for your body weight, you could opt for the comfort of a topper.

We make two ranges of pocket sprung mattresses, our Origins Range which have synthetic fillings and our Artisan Range which have natural fillings.  In the Origins Range, I would recommend looking at our Origins Pocket 1500 which will give you both the support you need together with a more medium feel from the top upholstery layers (comfort layers).  In the Artisan Range, the first four mattresses in that range all have a medium comfort layer and we can also make those mattresses with a medium spring tension for support.

I trust that this assists but please do not hesitate to contact our office for further advice/guidance on 0161 437 4419.

Kind regards Julie
