Hello Iris,

I am sorry to hear of your health issues, but hopefully I will be able to guide to a suitable product.

We would not normally recommend a firm mattress for people with your body weight, but I note that this is what you prefer, and If zip and link is an imperative, then please view the Origins Pocket Latex 1500 which is available in a zip and link option for king size and above.

Once you have viewed these products through the links above, please call our office for more specific advice as to the suitability of your choice.

Kind Regards Gary
