The pet bed feels to be constructed of soft foam sandwiched between and outer layer of stiff fabric and inner lyer of softer material. It does not have much shape so my dog easily can flip it onto its side when trying to get in.
 
When it arrived, it was shipped in a compressed bag. It still has some wrinkles even after several weeks of use. It off-gassed for several days so I sprayed it with some essential oils.

Overall, my pets seem to find it cozy. I do wish that it was either a bit  heavier or sturdier to better maintain its shape.he
