COMFORT: 
The Interlude Firm is the firmest in Therapedic's premium Bravura™ collection. This model is popular with those who might want a firm bed, but don't want to feel like they are sleeping on a carpeted floor (even one with good carpet padding)
Because the Interlude Firm it isn't too stiff, it is very popular with side sleepers who don't have an issue with shoulder or hip conformity and extremely popular with stomach sleepers who tend to prefer a slightly firmer bed anyway.
