The Origin mattress and the Polysleep mattress are both very confortable. Unfortunately, they are on the softer side. I would much prefer if they would be firmer. I prefer the origin mattress when sleeping with my boyfriend because in the Polysleep we sink both into the middle of the mattress because of the sides reenforcement. With the origin mattress that feeling of sinking in the middle don’t occur and we sleep better in it. The fact that it is 8 inches instead of 10 don’t change anything at all. We can’t even feel the difference. I would suggest you buy the Origin if you hesitate between it and the Polysleep model.
