Absolutely unacceptable business practices. I have asthma and had concerns about ordering memory foam mattresses. Wayfair told me there was no fiberglass or health concerns with having fiberglass as insulation in their mattresses. I didn't learn until over 5 months later well outside their return date that there was FIBERGLASS in Wayfair sleep mattresses!!! This is incredible dangerous. And do you know how fiberglass can get out of the mattress? By cleaning it, unzipping it or just sleeping on the bed too much!! This should be illegal. And they won't issue a credit or a refund or anything to assist me because it's outside the 100 days.
