Single Bed (base) with barely used mattress (Felixstowe IP11)

I have recently upgraded to a double. The bed base is sturdy with some stain at the bottom due to the spilling of a cup of tea! The mattress is about 3 months old and has only been used by myself. I have always used a mattress topper, so it's clean and fresh.
