Hi dottydm,
[quote]I am looking for some impartial reviews on a sofa bed we are thinking of purchasing for a guest room. We are looking at the Sleeper Sofa Memory Foam Mattress By Classic Brands 414800-11

I don’t have any personal experience with the mattress but based on their description here the materials appear to be good quality and meet the quality/density specs in post #4 here. I would be cautious using memory foam with a thin sofabed mattress though because you may sink into the memory foam too much and feel the bar underneath. Post #2 here also includes a few good sources for sofabeds.
I wouldn’t put too much weight on mattress reviews because a mattress that works well for one person may be completely unsuitable for the next person to sleep on in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences). For the most part reviews are written shortly after a purchase by consumers who know very little about the quality of the materials inside the mattress they purchase so they are more about initial subjective impressions that may not be relevant to the longer term or to anyone else. You can read more about mattress reviews in general in post #13 here.
Just in case you haven’t seen it yet … I would make sure you’ve read the mattress shopping tutorial here.
