I'm looking for a good full-size mattress that still has a lot of life to it that is less than 10 years old and I'm also looking for a king size mattress. That's not hard. That's something in between soft and hard. That's also less than 10 years old both my mattresses that I have used are over 10 years old and need to be replaced and currently I do not have the funds to do so so thank you in advance.
