I ordered this mattress it was delay for over a week. When it was delivered I got help to unbox it, for over 7 days the mattress was left to inflate but it only  got to about 12 and if you sit on it sink down to about 4 to 5  . 
I  call wayfair and was told  to expect an email from the seller  when I  uplode the photos I got a next email offering me 20 off the price...I  ordered 14 Firm I had a 12 firm Prior am very frustrated because I  dont need the back and forth.
The issues is still unresolved .
Think twice an uncomfortable mattress affects ones health.
This is unacceptable.
