I was not too sure that this Sealy memory foam mattress would work out for me.  The mattress arrived first and I was not able to place it on the adjustable bed, until it arrived.  I  left the mattress in its shipping box until the arrival of the adjustable bed.  When the adjustable bed arrived I placed the foam mattress and left it alone for 24 hours.  It does have a strong rubbery odor.  I slept on it for the next 2 days to see if the odor will go away.  A mattress cover helps.  I think with time the odor will not be so apparent.  So far, It is a very comfortable light mattress.
