Hi Martyn,

Thank you for your question.

Mattress toppers are ideal for added mattress protection as well to soften up any firm mattress.

Given your requirements, I would recommend our Laygel Hybrid Mattress Topper.

This has a depth of 7.5cm and is very soft feeling giving that extra comfort as well as support.

It is also fully turnable, which gives an increased lifespan as long as it is flipped and rotated once a month.

I hope this has answered your question fully but if you do have any further queries, please don't hesitate to contact the office on 0161 413 2495.

Kind Regards, Lee.
