Great to hear all this awesome advise. Here are my thoughts on protecting the bed. Since I only occasionally bedwet I do not wear protection to bed except when not sleeping at my place. To protect my bed I have a waterproof cover over the mattress first. It has a plastic back and a very thin quilt poly layer on top. Over that I have a higher quality waterproof mattress cover with a softer and thicker quilted layer on top. Over that I have a regular cotton bottom fitted sheet. Now that sounds like a lot but it give me two layers of waterproof protection.
I then have a long quilted waterproof bed pad that I got form Amazon (RMS Ultra Soft 4-Layer Washable and Reusable Incontinence Bed Underpads, 34"X72"). I sleep on this and it is great. Very comfortable, feels like a soft bed. it is not hot or crinkly or uncomfortable to sleep on. Also since it is the length of my bed I don't have an issue with it moving around or working that I will move it to where it is not protecting the bed where my mid section is at.
This system really works for me and makes wet mornings easy to deal with. I only have to wash the long waterproof bed pad, my sleep clothes and the top sheet that was over me. Rest of the bed is dry and no need to change out or remake with fresh sheets.
To @snow question about keeping the top sheet or comforter dry here is how I handle it. The top sheet does get wet as it is over me but I put a small waterproof bedpan form IKEA between the top sheet and the comforter right at the mid section of the bed where if I bedwet the top sheet might get wet. The bedpan is soft and very flexable so it is not stiff or crinkly like some waterproof pads for cribs are.
So far my set up has kept the mattress and fitted bottom sheet dry and clean and the comforter dry and clean.
I hope this might help someone with ideas on how to protect their bed if needed.
