Have had this for over a month now, and I still find it comfortable. I need something more firm due to lower back problems, and this fits the bill. The cool gel seems quite cool when you first get into bed, but I do notice this mattress it a bit more on the warm side throughout the night. Still, it is much more comfortable than the old inner spring I slept on previously. Good purchase for the money. Oh.....I did let it air out for 4 days on the floor before putting the sheets on and placing it in our frame. I don't notice a smell anymore with the mattress, but I still do with the pillows. I prefer my old pillow, though, so I am not sleeping with the pillows that came with the mattress.
