Hi Katherine,

Thanks for your question.

We can do an Extra King Size Mattress Topper for you but as it is a non-standard size there would be an additional 10% charge on the cost of a standard Super King Size as we would then reduce the length from 6FT 6" to 6FT 3"".

Please note that as they are non-standard sizes there is no 60 day love it or return it guarantee as we have limited resale ability on items such as those.

I hope this helps but if you have any further queries please don't hesitate to contact our office on 0161 437 4419.

Kind Regards, Lee.
