Received on-time. Mattress inflated very quickly. No odor at all but I had my window cracked with the ceiling fan on all day. Right now I also have a box spring and I got a new bedroom set. Iâm only 5â3â and I have to literally climb into bed. The mattress is incredibly comfortable! In the next few weeks Iâll be swapping out the box spring for a âplatformâ type base to lower the bed height. But I absolutely love my mattress!!
