Is a duvet cover needed?
No, but it is recommended to keep it clean. A cooling duvet is good for hot sleepers as well.
How does the returns process work?
Contact the company within 30 days for authorization and pay for return shipping.
Where can these be shipped?
Do they fit a bed?
Yes and no. They are designed for single sleeper use and do not quite cover the whole bed. However the company does provide whole bed sized for dual sleeping, and they are always accommodating customer needs and adding to what is wanted.
