Congrats on having a bed. Definitely worth it, even if you have to get one special made. Sleeping on a pad on the floor, or on beds you can't quite lie down properly in is, well, not quite "miserable" - more like inconvenient or annoying - but over the long term it can contribute to a nagging feeling that you're not quite able to fully participate in the benefits of human civilization.
And that's an unpleasant feeling. It can lead to depression or make depression worse. So it's worth correcting these little "inconvenient" or "annoying" things as the opportunities arise. Their importance is individually small but the effect of many such little nagging things is something to just stop, as soon as you possibly can.
But, short form: Congrats on getting yourself a proper bed. Sometimes small things have more importance than it seems.
