This Durango Firm mattress from Denver Mattress has been comfortable. We bought it in early March. We have no complaints. Our backs don't hurt like they did on our old mattress (which was 15 years old).
The "new"/plasticky smell took about a week to go away; I would pull up the mattress pad and sheets every morning to air it out, hoping that would help. It is taller than our old bed because the mattress is very thick. You've got to watch the blankets and covers you buy--they are easily too short and won't tuck under the mattress. Sheets are usually made big enough these days.
