We are quite surprised that Equinox is considered a "winner" for it's cabins, as this was by far the smallest, most uncomfortable cabin out of 16 cruises we've done to date! At just 8'6" wide at the widest point, minus the furniture and countertop, that leaves very little space to move around.
The bed is curved out of necessity --- you would not be able to negotiate getting to the balcony door without the corners having been "removed" from the bed. But for tall people like us (DH is 6'3" and I am 5'11"), our feet hung over the bed by a good 6 inches, which was very uncomfortable indeed!
Add to that the fact that apparently, "X" does not have queen size sheets! For the first 8 of our 11 nights on board, our queen bed was made up with a twin size sheet, turned sideways to have some sheet on the side to tuck. Result: our feet not only hung over the end, but had no covering! We continually were removing and turning the twin sheet tback to it's proper orientation so our feet were covered, but of course, that left no sheet on our sides!
