Sleep Pattern
I again laid down around 8:30pm but this time didn't actually nod off until just after 10pm. So it took me a little longer to go to sleep than the previous day; but I woke up (my usual wake up before the "official wakeup) around 4:30 am this time. So while it took longer to go to sleep, I slept longer before being woken up. I'm almost confident this is because of noise outside the window; because it's a Saturday, there are less cars flying by my window early morning than there would be on a weekday. This may very well be skewing the experience.
It will be interesting to see what my sleep pattern is like after getting the windows replaced; unfortunately the windows won't be replaced until likely after this 30-day period; so I may need to a follow up period afterwards. I don't want to extend the period because there will a come a point that there won't be any significant change in results.
Body And Positioning
But what is not affected by the windows is my body and posture. Again I woke up feeling rested and not groggy despite not getting a full undisturbed sleep. However, unlike yesterday, I did have two occasions where the body heat overcame my position and I had to pull the comforter back to release it. It didn't happen after that; the mattress didn't feel hot, but I certainly did, more so than the previous day. So it seemed as though the mattress hit a point of not being able to absorb additional heat, but that point or threshold was significantly higher than other mattresses.
It felt like I did more tossing and turning than I did the previous night. I simply could not get comfortable. On the two occasions that I laid on my back and just turned my head, I was comfortable, but I hate sleeping in that position. Goes back to what I said about back sleepers vs. side sleepers in terms of getting used to the mattress. I think as a side sleeper there is just a longer break-in time, unfortunately.
Unexpected was the presence of pain on my right hip area. It wasn't on the bone, just above it. This was just before rolling onto my back, where the pain seemed to move (meaning the mattress was contributing to it). It wasn't unbearable pain, but pain regardless. It felt like it was around my diaphragm area, which likely means the mattress didn't have enough "give" to allow my breathing to work properly (your diaphragm expects to move smoothly upwards to expand and contract your lungs. Anything pressing against your front, side or back can impact this experience, resulting in pain or at least the perception of pain). If that's the case it might contribute to snoring, something I don't do. The abdomen/back pain continues as of the time of this writing, though a lot less subdued. I have to actually focus on it and move around to sense it. Hip pain is almost non-existent.
Mattress Durability
I again noticed that the mattress again did not look like anyone had slept in it. However, pressing down on the mattress revealed a clear softness in the place where I was sleeping vs. where I wasn't. It still kept its shape nicely, but most certainly was not firm in that area. It didn't go down more than an inch or so before again hitting resistance. This is similar to the no-name memory foam mattress I mentioned after I first bought it; it would initially be firm, but as heat increased, would get soft and eventually not go back to original shape. I will update tomorrow's results with tonight's "press test". If it goes back to its original firmness every time then the softness isn't that big of a deal.
I will be able to sleep on the mattress three more days, then I'm off on business travel for four days, then I'll pick up where I left off. Unfortunately sleeping in a different (likely spring) bed is going to throw off my body's adjustment. Might be a good thing since it's closer to the reality of bed adjustment anyway.
