Mattress Forum

I have been lurking around these forums for the past few days. There seems to be lots of knowledgeable peopole here, and I was hoping someone could offer some input.

I am 6', 160lbs, trying to spend max $150 on a topper. I need a full-size.

I don't want to spend much more than this, because I will probably be moving in May, and I don't know if I will be able to bring whatever topper I purchase with me.

The place I just moved already has an Ikea "Sultan Fangebo," but it seems a bit hard to me. I have spent some time laying in the TempurPedics and I like the feel, although I realize I likely won't be able to get the same sort of experience with simply adding a mattress topper and such a small budget.

I am leaning towards ordering either 4" of 4lb, or 3" of 5lb, from the from Foam Factory, but I am reading mixed reviews on them.

I have also been considering the 4" spa sensations mattress topper from Wal Mart.

I am also open to other suggestions.

All things considered, who provides the best value memory foam? Is Foam Factory reliable? If so, which would be more TempurPedic(ish), the 4" of 4lb, or the 3" of 5lb?

Basically, what are my best options if I only want to spend $150 improving my sleeping situation?
