This California King size mattress has been a saver than my old king size mattress. Very comfortable, sturdy and long enough for 6'5" bed user. I love it. It's a little bit less wider than my old king mattress bed frame but no biggie coz it's worthy. This mattress saves me a bit of money than buying it in a local store since you have to pay for delivery fee and the original price of the mattress. The delivery has been easy being arranged & they placed the mattress to where you want it to be & haul out my old bed with no cost to me. Thanks Overstock.com.
