Hi Hadouken,
As you can see in mattress firmness/comfort levels in post #2 here … your own personal testing and experience is really the only way to know with any certainty whether a mattress is suitable for you in terms of PPP (Posture and alignment, Pressure relief, and Personal preferences).
I can certainly tell you though that the materials are good quality, there are no obvious weak links in the mattress (poor quality materials that will compress or break down quickly) and like all the Parklane mattresses has very good value.
