I have a UGQ quilt that I love. I'm a side sleeper and they have extra wide sizes to give plenty to tuck in. A quilt is great when it's time for the 3am pee - no zippers to deal with getting in or out.
The UGQ comes with 2 straps but I've never used more than 1 and that one only on the back side. The extra width tucks in easily and the strap isn't needed.

Mine is a 10 degree and it's warm enough down to about 25. Like most higher end bag makers, they use the European system of warmth ratings. The listed rating won't keep you warm at that temp, it'll keep you alive. Add 10 to 20 degrees to the rating to see where it'll keep you warm.
