So, i've read lots about latex and memory foam, but haven't read much about plain old PU foam...Does anyone sleep on this, and what are the pros/cons of this foam? Is it ever better than memory or latex? Thanks!

I've slept on it.
Pro: It can be firmer than talalay and memory. Like other foams it can dampen movement. It can be hot, but significantly cooler than memory foam. It's cheap.

Con: It smells. It wears out quickly (you can pay more for high density or r foam that will last longer). I've found that even with the firmest density, it will give less support as it heats up, though much better than other foams (I have not tried dunlop).

Why did you choose it over memory foam or latex? Because of firmness and price?

I sleep on HR foam if you count that as PU. I guess it is.
But I always use it as a base and then use various toppers, from latex to memory foam. According to one foam expert I recently spoke with (though he is prejudiced, I guess in terms of "pushing "M-Grade" foam, which one cannot apparently even buy anywhere except for the online mattress store he works for), HR foam is lousy to sleep on because the sweat from your body breaks it down. I don't think this theory really holds water though if you put some kind of mattress cover or topper on top of the HR foam.

I went with HR foam for the following reasons:
1) I do not like laying on Talalay latex. I cannot stand the "push-back" feeling of it. I have not  tried Dunlop latex, though I would like to.
2) Memory foam in the past has been too soft for me to sleep on. I am not trying a Sensus memory foam, and would like to try a Venus memory foam.
3) HR foam is good quality and can be gotten in a variety of ILD's
4) HR foam is available near where I live at a distributor for very low prices and they'll cut it to my specs.

Being that I have back and shoulder and neck problems from 3 different car accidents, my case is somewhat different than the average person, so what I like and what I can sleep on is probably more specific than other people.

For example, I recently tried a mattress from overnightmattress.com which consists of M-Grade foam and memory foam. It was a very good mattress at a very good price! BUT I had to send it back because after around 2 months it began to break-in too much and become a LITTLE too soft for me. They have a 120 night sleep trial so I did send it back.  BUT, I do recommend this mattress for most people because I think most people would enjoy it and not find it too soft. I need a very delitcate balance between "soft enough" but not "too soft", and for me, after 2 months or so it began to become just a little too soft.

I also think MOST people would do better buying a 6" slab of 33ILD or so HR foam and then trying various toppers on it, rather than buying an "S" brand bed.... AND they'll save aboout $600-2000 in doing so!

IF you wanna get fancy you can do what I do, which is buy 1" slabs of HR foam in various ILD's, cut up into thirds, a top a middle and a bottom section, then take those 1" sections and arrange them in various ways to create a customized softness for your shoulder section and hip section. For example: a 33ILD 1" section on top of a 36ILD section for the shoulder, and a 33ILD 1" section over a 41 ILD 1" section for the hips, etc etc., all then covered with a topper of your liking. (I'm currently using Sensus memory foam which is working, but may soften up too much over the next weeks.)

But again, I think the AVERAGE person without back or neck or shoulder issues, can sleep just fine on a medium ILD 6-8" slab of HR foam with some kind of topper or at least a mattress cover.

My husband and I have a three quarter inch very dense HR layer of PU foam over our LuraFlex coils and under our firm talalay latex layers. It's very high quality with a long warranty for wear.
