The elbow directly behind the machine is where it packs first, because the hose gets crushed when you push the dryer back against the wall. Semi rigid duct instead of the flexible foil kind mostly solves that for good.

Rebuilt every sash in a 1920s terrace; will argue that old windows outlast their replacements.
The chair thing is genuinely the biggest single change. I put a lamp and an uncomfortable-ish armchair in the corner of the bedroom and my finished book count roughly doubled in a year.
The read aloud advice is the one I would push hardest. Mine went from abandoning chapter books to reading them alone over about eight months, and the only thing we changed was twenty minutes of me reading to him at bedtime.
Worth knowing this affects more than glasses. Hard water shortens the life of kettles and shower heads, makes soap and shampoo lather badly, and leaves that grey film on shower screens. A cheap test strip pack tells you the number, which is useful before you spend anything on a softener.
The thing I would pay attention to is not the smell itself but whether you have symptoms. If you are getting headaches, a scratchy throat, or sleeping badly and it lines up with the mattress, do not tough it out for months on the internet's advice. That is worth a conversation with a doctor and worth checking your return window, because most companies have a trial period and it is far easier to use it at week four than at week ten.
For what it is worth, no smell at all and a fast fade is more common with foams carrying a recognised low emissions certification, which is worth looking for next time.
