The guy who works for Icloud is full of it. 3-5 lbs is high quality... um first of all anything less than 3 lb memory foam is like sitting on a cheap sofa from Walmart. Not appropriate for a bed... or unless you weight 50 lbs. I would say it needs to be at least 4 lb or more. Tempurpedic is 5 lb memory foam just for reference. You get what you pay for here, not a deal at all.
the guy did say though, that the most comfortable density is the best density. that is true, because you can buy a 5lb-dense foam and feel like you're sleeping on sheetrock, or you can buy a 3lb-dense foam and feel like you're sleeping on a cloud.
this is completely based on your weight distribution as a person, and most likely your body temperature throughout the night.
i will tell you from experience that as a 145lb~ guy (an inch short of 6' tall) i cannot fathom sleeping at all on the 5lb-dense foams. namely, me and some, uh...larger friends went mattress shopping and came across a tempurpedic. i saw my two friends hop onto the bed and they just sank in, and told me how ridiculously comfortable it was.
naturally, i did the same. it felt like i jumped onto a very thinly padded plank at first and actually hurt a bit...and as i laid there, i gradually made an impression on the foam but never fully sank in.
this was on a 5lb-dense foam btw, i forgot what tempurpedic names those. i found another brand that used a combination of 3lb and 4lb-dense foams (bi-layered) really comfortable...and went with that instead.
