I do not have the mattress yet, so I will need to update my review later. But the customer service I have received via the online chat system has been awesome. At 10pm ET a live agent was actually available and quickly provided me with information about the materials and cover of this mattress. I have been searching for an affordable mattress that does not contain fiberglass. This agent attached the law tag that accompanies this mattress and links to other information I needed. It confirmed that I wanted to buy this product and I can't wait for it to get here.
