ROHO Prodigy Mattress Section

The Roho Prodigy mattress replacement section is about half an inch thinner than the old mattress and the waffle size is also slightly smaller.

The bed cushion is comfortable as it said, but the smell of the material(rubber? plastic?) kept me awake. The smell is not reduces after airing for three days. I will appreciate an instruction on how to get rid of the smell.
