However, a Firm spring tension would cover someone at your weight on a traditional pocket sprung unit. We would need to know how you prefer your mattress to feel in it’s top upholstery (also referred to as the comfort layers). All of our Pocket Sprung mattresses have very different feels ranging from a soft sink in sensation to more of a firm feel.
Our pocket sprung ranges (Origins and Artisan) can go on to a slatted bed base as long as the gaps are no bigger than 3″. If they are bigger than this then we simply advise placing some sheets of MDF or ply wood over them.
