Just found you are not recommending something good to the others. This brand made you suffer a lot and you still claimed it as GOOD???
Vana said her mum's Kingkoil cheaper model mattress is good.
my aunt also using Kingkoil expensive model but 5 inches also very good.
our mattress is bigger than normal size, mine is 5.5" wide custom made from Kingkoil and hers is 6" wide. i believe bigger mattresses have this prb. i tried airland and another Korean brand (forgot the name) also had the same problem.
