The mattress is advertised as firm but it's extremely soft; like sink-straight-down soft. I have a year-old medium mattress from Wayfair that's much firmer and more comfortable.  But that's not the biggest problem - the smell was!  The box the mattress was delivered in smelled like it had been dragged through dog poo.  It reeked so bad, I had to dump out the mattress in the hallway and throw the box outside right away.   Still my hallway stank for the rest of the day and I eventually had to air it out in 40 degree weather.  I needed the mattress right away so I sprayed down the plastic wrapping with Lysol just to be sure it was clean before opening it up.  The whole experience was awful.  I talked to customer service and they offered me 10% off my NEXT purchase. I've ordered a lot from Wayfair over the past couple of years, but after this, there definitely won't be a 'next purchase' for me.
