We bought the king size one 1.5 year ago and we have no complaint. Cost half of other big brand like Sealy etc...
Bed Frame is really depending
your preference, we checked out Brick, Leon, etc....but doesn't like them.
We bought ours at Ashley with the full 7 pieces bedroom set. Way better quality than Bricks or Leon or Ikea. There is a big difference in price due to the way better quality of solid wood, but we figure we will be sleeping on the same frame for the next 20 + years, worth the investment.
The mattress can be replaced every few years.
