I have already answered this on our previous feed, I state the following;
You will be relying on the laws of the Consumer Rights Act (CRA) in this matter. Firstly, as you are still in warranty then they should be fixing this for you. However, in relation to the CRA, you still have some statutory rights. If an item is no longer suitable for use then you can ask the supplier to repair or replace the item. However, as you have had it for a period of more than 6 months, the onus is one you to prove that the fault lies with the manufacturer. This can prove difficult. However, the first step of action I would recommend would be to contract the manufacturer and state that you have rights under the CRA and ask them to replace the item, additionally, I would continue to argue that you are still within warranty. If you do not get a resolution then you could raise action against them and I would make them very aware of this. However I as I stated above, you will have to show that it is the manufacturer's fault that the mattress is no longer suitable and this can be quite difficult. I would continue to purse that matter till exhaustion and hopefully knowing your rights you will be able to obtain a positive resolution.
