the cheapest will be about 4000, thats not a real bed.. more like a sprung divan base.
to get something that is more like what you'd find in the UK you will be paying closer to 10,000.
for a single 2inch thick (matteress cover thing) thats likely to be about 1000.
a comforter (duvet) is around 3000.
you get more for your money in the uk all told.
