When I walk a client through a bedroom that has run out of storage, I get down on the floor before I open a single closet. Under a queen bed there is more flat, dark, out-of-the-way space than in most dressers, and in nearly every house it is holding one lost sock and a lot of dust. Filling it well is the cheapest storage upgrade a bedroom can get: no new furniture, no wall to open up, nothing to assemble beyond a lid.
It is also the storage purchase most likely to arrive and not fit. Bins are sold by capacity and installed against a bed frame whose lowest rail sits a fixed distance off the floor, and that distance does not move. A generous seven-inch bin is useless under a low platform bed, a bin with no handles is miserable on carpet, and a bag that is perfect for blankets will crush a down comforter if you leave it there all summer. Every one of those problems is a two-minute check before you order and a return afterward.
So here are the five things that decide this purchase, in the order they matter. One, the clearance: measure from the floor to the lowest part of the frame, then subtract an inch - that is the tallest bin you should buy. Two, the pull-out path: how far the bin can slide before it hits a wall, a nightstand or a rug edge, which decides whether a long bin or two short ones fits your room. Three, the floor: hard floors reward wheels and punish bare plastic; carpet rewards handles and punishes small casters. Four, what goes in: hard bins with latches for things you want sealed, breathable fabric for natural fibers, and vacuum bags only for bulk that can take being squashed. Five, access: a lid you have to lift is fine for seasonal things and a nuisance for weekly ones, which is where drawers and sliding fronts earn their money. Then nine picks, one for each common situation: the standard clear bin, a gasket-sealed bin for keepsakes, a sliding drawer for things you reach for often, the cheapest honest fabric bags, a four-inch bin for low platform beds, a shoe organizer, vacuum bags for synthetic bulk, rolling drawers for hard floors, and risers for when there is no clearance to begin with. If the whole room needs a rethink, the storage and organization roundup covers closets and shelves, and the bedding guide explains what you will be storing in the first place.
One honesty note before you shop. I have emptied, measured and re-filled the space under a great many beds, but I have not run these specific products head to head in a lab and I will not pretend otherwise - every dimension and capacity below comes from the manufacturer’s own listing, every storage rule comes from a source I have linked, and where a listing does not state something, this page tells you to check rather than guessing on your behalf. Amazon pricing also moves all day, so where a live price is not available you will see a Check price on Amazon button rather than a number I cannot stand behind.

Hard bins, fabric bags, drawers or wheels
Under-bed storage comes in four formats, and each solves a different problem. Knowing which problem you have is most of the decision.
Hard plastic bins with lids are the default for a reason: they hold their shape, they stack when they are not under the bed, a latched lid keeps dust off, and a clear one lets you see in. Their weakness is height - the common sizes sit around 6 to 7 inches tall, which is why they vanish from the shortlist under a low platform bed - and access, because a lid has to be lifted and there is nowhere to lift it to under a bed. The 50-quart IRIS bin is the standard version; the gasket-lid one is the sealed version.
Fabric bags and structured fabric bins cost less, fold flat when empty, breathe, and are the only sensible container for natural-fiber textiles you care about. Plain bags slump; the structured kind with reinforced sides and a stiff base - the StorageWorks 4-inch bin here - behave almost like a hard bin while fitting where one cannot. The price is that they offer nothing against moisture on the floor or pests.
Drawers - a shell that stays put with a front that pulls - solve the access problem. You do not lift, you do not drag, so you actually use them. The cost is usable height, because the shell and the drawer both take some of it; the IRIS sliding drawer gives about four inches of inside depth from a six-inch footprint. Put weekly things in drawers.
Wheeled bins and rolling drawers are for hard floors and beds on legs, where the storage will be seen and has to move without scraping. The KITHELP set is the version here that is built to be looked at. On carpet the wheels are a liability, not a feature.
Two products on this page are not containers at all. Vacuum bags make soft bulk thinner so it fits where nothing else will; risers make the bed taller so the standard bins fit after all. Both are tools for changing the clearance problem rather than living with it.
What belongs under the bed - and what should never be sealed in plastic
The best candidates are the ones StorageWorks names: seasonal clothing, extra bedding and shoes you are not currently wearing. Under a bed is dark, which textiles like, and it is in a heated room, which is a real advantage over the alternatives - the George Washington University Textile Museum’s storage guidance says to avoid attics and basements, because those spaces usually lack climate control and suffer the largest swings of temperature and relative humidity (GWU Textile Museum). A bedroom floor is neither of those.
The container matters more than most people think. Down and feather fill should not go in sealed plastic at all. Puredown, a down bedding maker, says the best way to store a down comforter is in a large linen or cotton storage bag, and to avoid a plastic bag, plastic storage container or vacuum-sealed bag, because plastic tends to trap moisture and humidity, which can cause the down to turn yellow and develop a musty odor - and that compression or vacuum bags can crush the down clusters, permanently damaging their ability to loft and insulate (Puredown). The same guide says the comforter must be completely clean and 100% dry before it is stored, because a damp one can develop permanent stains and mold or mildew, and that the ideal storage environment is cool, dry and dark with good air circulation. That is the case for the breathable fabric bags on this page over the hard bins for anything with feathers in it.
For heirloom textiles - a christening gown, a quilt somebody made - the museum standard is worth knowing even if you will not hit it. The Smithsonian’s Museum Conservation Institute says its museums try to hold collections at 45% relative humidity plus or minus 8%, and 70°F plus or minus 4°, and recommends washable cotton sheeting as the dust barrier around antique textiles, in preference to plastic or paper, which transfer dust to the fabric (Smithsonian MCI). The same page warns that cockroaches find the corrugations in cardboard attractive and that silverfish and booklice eat the starchy components of paper, so excess paper and cardboard should be avoided. The practical translation for a bedroom: wrap the precious thing in a clean cotton sheet, put it in a bin rather than a cardboard box, and if the bin is a sealed one, make sure everything went in bone dry. The GWU guide adds that wooden drawers should be lined with acid-free tissue or barrier paper to keep wood acids off the fabric, which applies if your under-bed storage is a wooden drawer.
What I would not put under a bed, from experience rather than a source: anything heavy you will lift often, because you lift it from a kneel; paint, solvents or anything that smells, because you sleep two feet above it; and anything you would be upset to find wet, unless it is in the gasket bin. Sleep is the room’s job; storage is the lodger.
