Best under-bed storage: six boxes and bags from 6.1 inches tall, measured against the gap under your bed
Under-bed storage fails in one way: the box is taller than the gap. The second way is that it is longer than the bed is wide, so it sticks out. Four rigid boxes from Sterilite and IRIS and two fabric bags, compared on height, length, capacity and lid, with the makers' figures where the makers publish them and the listing's — marked — where they do not.

† Figure from a retailer listing or otherwise awaiting confirmation from the manufacturer; other figures come from manufacturer manuals and spec sheets.
Sterilite publishes exterior and interior dimensions for both boxes and those are what the table shows. IRIS’s site could not be reached, so both IRIS boxes carry the listing’s figures, marked pending. The fabric bags have no reliable dimensions from anyone — the Budding Joy listing gives 90 L in one place and 95 in another, and the Ziploc listing gives none — so their size cells are empty and their capacity is marked.
Height first, then length
Measure the gap from the floor to the lowest part of the bed frame — the side rail, not the slats — and subtract an inch. That is the tallest box that will slide in and out full. The rigid boxes here are 6.1 to 6.9 inches tall, so they want 7 to 8 inches of clearance; a platform bed with 5 inches gets a fabric bag or nothing.
Then length. A box goes in from the side and runs toward the middle of the bed, so under a queen (60 inches wide) a 34.9-inch box fits from each side; under a twin against a wall (38 inches) only one, and a 23.8-inch box fits with margin. Width matters less: it runs along the bed, and there is usually more of it than you need.
Last, the lid. A snap lid comes off when the box is carried full; a latching lid stays on. A zip on a fabric bag keeps dust out and nothing else.

Sterilite’s page gives the 1960 as 34.9 by 16.6 by 6.1 inches outside and 30.5 by 12.75 by 5.4 inside, 41 quarts, a clear base with a white snap-on lid and no wheels. Six come in the pack, which is two beds’ worth. At 6.1 inches it is the lowest rigid box here and clears most frames.
No wheels means a full box drags on carpet; the snap lid is not a latch; and six is too many for one bed.
For sweaters and bedding under a bed with 7 inches of clearance, or a household doing two bedrooms at once, it is the standard answer.
Strengths
- 6.1 in tall clears most bed frames
- Clear base — you see what is in it
- Six boxes: enough for a whole bedroom
Limitations
- No wheels: a full box drags on carpet
- Snap lid, not latching
- Six is too many for one bed
Good for
- sweaters and bedding under a bed with 7 in of clearance
- a household organizing two bedrooms at once
- stacking in a closet when not under the bed
Look elsewhere if
- a bed with 5 in of clearance
- heavy loads you pull out often

Shorter and latched: 23.8 by 16 by 6.9 inches outside, 20 by 13.4 by 6.4 inside, 32 quarts, with clips that hold the lid on when the box is carried, and Sterilite’s own page says it fits under a bed. It stacks when latched, so in summer it can move to a closet shelf.
At 6.9 inches it needs more clearance than the 1960, 32 quarts is a sweater drawer rather than a bedding box, and it is a six-pack again.
For shoes, sweaters and papers under a bed with 7.5 inches of gap, or a box that moves between bed and closet, it is the one.
Strengths
- Latching lid stays on when you carry it
- Short enough to fit sideways under a narrow bed
- Stacks when latched
Limitations
- 6.9 in tall — needs more clearance than the 1960
- 32 qt is a sweater drawer, not a bedding box
- Six-pack again
Good for
- shoes, sweaters and papers
- a bed with 7.5 in of clearance
- a closet shelf as well as a bed
Look elsewhere if
- bulky bedding
- a low platform bed

The listing gives 40 quarts, 28.5 by 18.1 by 6.3 inches, buckle latches on four sides and a gray lid; IRIS’s own site would not load, so every figure is marked pending. It is shorter than the Sterilite 1960 and sold one at a time.
No wheels, the lid hides the contents from above, and the dimensions are the retailer’s.
For one box for one bed, clothes and shoes, and 7 inches of clearance, it is the single-box option — bought knowing the numbers are unconfirmed.
Strengths
- Buckle latches on four sides
- Shorter than the Sterilite 1960 — fits a narrower bed
- Sold singly
Limitations
- All figures from the listing; IRIS's site was unreachable
- No wheels
- Gray lid hides the contents from above
Good for
- one box for one bed
- clothes and shoes
- a frame with 7 in of clearance
Look elsewhere if
- anyone who wants maker-verified dimensions

The biggest single box here by the listing: 50 quarts, 32.5 by 17.8 by 6.5 inches, with an interior of 28.5 by 15.25 by 5.75 and buckle latches. The interior figure is the useful one — it is the size of the comforter you can fold into it — and again IRIS’s site was unreachable, so pending.
Six and a half inches tall means measuring the bed, there are no wheels on a box this long, and the figures are the listing’s.
For winter bedding under a queen or king with a long clear run, one big box instead of two small ones, it is the one.
Strengths
- 50 qt swallows a comforter
- Interior dimensions stated, not just exterior
- Latching lid
Limitations
- 6.5 in tall: measure the bed
- No wheels on a box this long
- Listing figures only
Good for
- winter bedding
- a queen or king bed with a long clear run underneath
- one big box instead of two small ones
Look elsewhere if
- a bed with less than 7 in of clearance
- frequent access

Four soft bags of three-ply non-woven fabric with a clear PVC window on top and a zip, which fold flat when empty and squash into a gap no box fits; the listing claims 95 liters each in one place and 90 in another, there is no maker page, and so every figure is pending.
Fabric is not dust-proof the way a latched box is, the handles do not like a heavy load, and the capacity is whatever you can stuff.
For a low platform bed and bulky soft things — duvets, pillows, winter coats — rotated by season, it is the practical choice.
Strengths
- Soft sides squash into a low gap
- Fold flat when empty
- Clear window on top
Limitations
- No maker spec page; the listing's own numbers (90 and 95 L) disagree
- Fabric, so not dust-proof like a latched box
- No handles that survive a heavy load
Good for
- a low platform bed
- bulky soft things: duvets, pillows, winter coats
- seasonal rotation
Look elsewhere if
- shoes or anything with corners
- a damp basement

Two zippered fabric totes in Ziploc’s under-bed size, 17 gallons each, with built-in handles and a washable body by the listing; neither the listing nor Ziploc’s page, which could not be loaded, gives dimensions you can plan around.
Floppy when half full, not usefully stackable, and sized by a number you cannot check against the bed.
For clothes and linens under a low bed as a quick cheap fix, fine; for anyone who needs to know the size before it arrives, no.
Strengths
- Zipper closure and built-in handles
- Two in a pack
- Cheap and washable
Limitations
- No usable dimensions from Ziploc or the listing
- Floppy when half full
- Not stackable in any useful way
Good for
- clothes and linens under a low bed
- a quick, cheap fix
Look elsewhere if
- anything heavy or with corners
- anyone who needs to know the exact size
How to choose
- Measure the gap. Floor to the lowest frame rail, minus an inch. Under 7 inches: fabric only.
- Measure the run. From the bedside to the middle of the bed. 34.9 inches (Sterilite 1960) needs a queen; 23.8 (latching) fits a twin.
- What goes in. Corners and weight: rigid. Duvets and coats: fabric.
- Lid. Latching (Sterilite 1496, both IRIS) if the box is carried full; snap (1960) if it only slides.
- How many. Sterilite sells six; IRIS one; the bags four or two.
Who should buy a closet shelf instead
Under-bed storage is for things used twice a year. Anything you need weekly ends up on the floor beside the bed, and a 35-inch box full of sweaters drags on carpet every time. If the gap is under 6 inches, or the bed is against a wall on one side and a nightstand on the other, a shelf in the closet beats anything on this list.
Which one, by situation
- Two bedrooms, standard frames: Sterilite 41 qt 1960.
- A twin, or boxes that carry: Sterilite 32 qt latching.
- One bed, one box: IRIS 40 qt.
- A comforter: IRIS 50 qt Long.
- A platform bed: Budding Joy bags.
- Cheapest possible: Ziploc totes.

How much clearance do I need?
The box height plus about an inch, because the lid rides up a little when the box is full and the frame's side rail is often lower than the slats. A 6.1-inch Sterilite 1960 wants a 7-inch gap; the 6.9-inch latching 1496 wants 8. Measure from the floor to the lowest part of the frame, not to the mattress.
Lengthways or sideways?
A box goes in from the side of the bed, so its length runs under the bed toward the middle. A 34.9-inch Sterilite 1960 under a 60-inch queen leaves room for one from each side. Under a 38-inch twin against a wall there is room for one, and a 23.8-inch latching box fits with margin.
Rigid box or fabric bag?
Rigid for anything with corners, anything heavy, and anywhere dusty; the lid keeps dust and moths out and the box slides. Fabric for a low bed, for soft bulky things like duvets, and for folding flat in summer. The bags here have no published dimensions you can rely on, so buy them for what squashes.
Quarts, liters or gallons?
Sterilite and IRIS sell by the quart, the fabric bags by the liter or the gallon. A quart is about 0.95 liters; a gallon is four quarts. So the 95-liter bag claims about 100 quarts, the 17-gallon tote 68, against 41 to 50 for the rigid boxes — but a soft bag's capacity depends on how hard you stuff it.

Best airtight food storage containers: five sets for the pantry, the fridge and the lunch bag, on the makers' rules
Food containers are three products sold under one name: canisters for dry goods, boxes for leftovers, and boxes that carry lunch without leaking. Buying one set for all three gets a drawer of mismatched lids. Five sets from OXO, Rubbermaid, Snapware, Pyrex and Sistema, compared on sizes, materials, seals and the makers' own microwave, oven, freezer and dishwasher rules.

Measure before you buy storage: the under-bed gap, the shelf depth and the fridge, in inches
Storage products are returned for one reason: they do not fit. The box is taller than the gap under the bed, the canister is deeper than the shelf, the container does not go in the fridge door. This guide lists what to measure, where, and what to subtract, with the published dimensions of three boxes and a canister set as worked examples and the quarts-to-liters arithmetic the labels assume.
