Was so excited to receive in such a timely manner, opened it, and the chemical smell was very strong. Let it air out overnight in our living room, but the smell permeated the whole house. Moved it to the garage for two whole weeks. Still had too strong of a smell to put on bed as was. The smell is NOT covered by warranty only impression size. Could have put this $$$ to much better use. Maybe one without the gel would not smell as bad???
