Got this mattress for the guest bedroom to go with the soho queen frame. Fits the frame just fine. So far, both sets of grandparents have slept on it since our newborn was born and they report that it's very comfortable. One set of grandparents likes a firmer mattress and the other set has a pillowtop coil mattress at home (softer sleeping surface). Since they both seem satisfied despite their differing preferences, it seems like a great purchase! One set of grandparents now are saying they're going to buy one for themselves at home and get rid of their spring coil mattress!
