I just purchased a Helix Twilight Mattress.
I slept on it for 4 nights (with a zippered mattress protector and a quilted top and sheets). Even though this is supposed to be a firmer mattress, I realize that it is too soft for me. My previous mattress was a futon on a board.
They won't let me return the mattress for at least 30 days and there are return fees involved.
I want to move the mattress along to someone who will enjoy it.
The mattress is in perfect condition and has never been slept on directly. (It was covered with protectors and layers when I slept on it.)
