Regretably we do not have a solution to your problem other than to change your base. The mattress you have can be placed on a bedstead base, but it will change the feel of the mattress.
A ‘bed’ is a mattress and a base working together, you should not consider them in isolation and should ideally always try them together. We always recommend you buy them together because the two are designed and manufactured to compliment one another in terms of support.
