SpaceAid Jumbo Vacuum Storage Bags, Space Saver Sealer Compression Bags for Comforters, Blankets, Pillows, Bedding, Clothes (X-Large 3 Pack)

Why it's worth it

Three jumbo bags that compress a comforter down to a firm slab you can slide under almost any bed. Good Housekeeping's textile lab found vacuum bags cut the volume of bulky bedding by as much as 80 percent, which is the one trick no rigid box can do.

If your platform bed leaves less than 5 inches, this is the answer. Wirecutter's editors found that platform frames often drop below that, which rules out nearly every rigid bin, including all three of our other picks. A vacuum bag doesn't have a fixed height. You compress until it fits, and a queen bedding set that started as a shapeless pile ends up flat enough to slide into a gap a box can't enter.

Each bag is 27.5 by 39.5 inches, which SpaceAid says holds four standard pillows or a full queen bedding set. You put the items in, zip the double seal, and pull the air out with any regular vacuum cleaner. There's no pump to buy or lose. The valve seals when you lift the hose off, and the whole job takes a couple of minutes per bag.
