I had to hire a professional to assemble it, and sleep number chat was NO help. And then they would not pay for the assembly and wanted me to take apart the mattress and return it. The mattress was better than my former memory foam mattress, but NOT much. It definitely was NOT worth the $600+ the $100 assembly. Even if i end up getting a refund, i am STILL out the $100+ for the assembly. I am glad that i saved the memory foam mattress.
