Hi Huntlip,
You could ask them to make sure but I believe their warranty is 10 years and there are no returns on the mattresses on the Amazon site once they have been unpacked. Some of their mattresses have layer exchanges but not the gel memory foam.
They are just in the process of launching the Brooklyn bedding site and at this stage only have 3 latex hybrid mattresses listed there but more are coming apparently.
Post #12 here should help
