I purchased and slept on a very expensive $4000 Tempur-Pedic King sized mattress for the four long years when I lived in Shanghai, and I didn’t like it except in spring and fall. It was like sleeping on a cold brick in the winter and a hot sweaty soft mattress in the summer. I left it behind.
This mattress is more firm than I originally thought. When I sat on the edge of the mattress, it seems to be very soft because I sink into the mattress. However, when I sleep on it, it is actually rather firm. And that’s because my weight is more distributed instead of being concentrated in one spot when I sit on the edge..
This mattress is 60 inches wide and 82 inches long and a little more than 10 inches thick. You can get a thicker mattress, but I don’t think it will affect the firmness. The last two name brand conventional mattresses I purchased were several inches smaller than standard in both width and length..The furniture store refused to take them back. Fortunately, this mattress is a normal size, but not quite as thick as my conventional spring mattress. The additional width and length offset the thickness difference for a fitted sheet, so that works for me.
It was amazing to watch this mattress inflate and take shape after taking it out of the shipping box. It is even more amazing that it fit inside the shipping box. I’ve included a photo sequence to show you what to expect. The Sleep Innovations 12 inch mattress has an astounding 3383 overwhelmingly positive reviews. I just wish I had known about Sleep Innovations mattresses before now. —M Cox
