But yes, they’re missing from the write-up.
Also it’s incorrectly(?) calling all of them “throw” size, when it should probably be
10lb throw 50×60″
12lb twin 48×72″
15lb twin 48×72″
15lb queen 60×80″
At least, that’s how they did it last time.
I disagree a bit with the labels (my twin beds aren’t really 4 feet wide…) but they’re close enough. Maybe this version is calling them all “throw” so that no one can complain that it’s not really twin size or queen size.
In any case, just be sure to watch the dimensions and you won’t be too surprised.
