I had a king size feather pillow which is too big for me to use so I sized down to two of these standard size with the gusset sides. Very nice quality pillows. Just the right size and fill. The description says machine washable but I’m not sure about that. I’ve never machine washed a feather pillow. Maybe freshen it up by putting in the dryer with towels for a few minutes but not machine wash. Great quality.
