Good mattress.  Not superb.  I wanted a soft, foam mattress but did not want a really heavy 12+ inch mattress.  Size is perfect, weight is ok.  But could be softer.  Is foam but not "memory foam".  After a week the top and bottom are still a little scrunched but does not affect anything.  Delivered quickly, price is awesome.  Appears to be well put together.  Perfect for someone who wants a medium to firm mattress.  Thinking it will last for a lot of years.
