Under-bed storage with wheels: what to measure first

Under-bed storage is only “free space” if you can get it in and out again. A box that fits on paper but has to be dragged out on your stomach will not be used. That is why under-bed storage with wheels is worth considering in a family home, especially in a child’s room where children may be the ones fetching spare bedding or out-of-season clothes.

This guide is about measuring first, then choosing a style. It is desk research into listed dimensions, not a hands-on test. For a scored top ten, see our best under-bed storage for families.

How much space do you need under the bed?

Ignore the marketing photos and take three measurements, in centimetres, with the bed made as you usually have it.

Clearance height. Measure from the floor to the lowest obstacle: the slats, a side rail, a centre beam or a bedding skirt. Do this in more than one place; some beds dip in the middle. The box must be shorter than this clearance, with a little to spare so it does not scrape.

How much spare? A few centimetres is wise. Wheels add height compared with a flat tray, and a slightly uneven floor will show up here. If the listing says 18 cm tall and your clearance is 18 cm, it will not be a comfortable fit.

Width and depth of the gap. Measure how far the box can slide in from the side or the foot of the bed, and how wide the opening is between legs or drawer pedestals. A pair of large drawers may fill the space under a single bed, but a divan with existing drawers, or a bed with a low side rail, may only take slim boxes from the foot end.

How you will pull it out. Leave a clear path beside the bed. A wheeled box is of little use if a cot or a chest of drawers blocks the only direction it can travel.

Write the height on your phone before you shop. It is the figure most people guess, and guess wrong.

Wheeled drawers versus wheeled boxes

Wooden or solid drawers on castors

These look like furniture rather than plastic, which matters in a child’s bedroom that also has to feel calm. The Libra wooden underbed drawers from Junior Vida are the number one pick on our main list: a set of two, listed at 91 x 60 x 20 cm each, in solid pine with round wooden handles and four wheels. At 20 cm tall you must have enough clearance; they will not suit a very low frame. A pair can fill most of the space under a single bed, according to the size. Children can often manage the handles themselves, which is the point of wheels in a kids’ room.

Plastic boxes with lids and wheels

These are usually shallower, easier to wipe, and better when you want a lid against dust. The Argos Home 2 x 45 L wheeled underbed boxes are listed at 90 x 38 x 18 cm each, so 18 cm is the height to check. Dunelm’s Smartstore 60 L box on wheels is listed at 59 x 80 x 18 cm — a single large box rather than a pair, useful for a folded duvet. The Muddy Hands 32 L boxes (pack of two) are listed at 60 x 40 x 18.5 cm, with clear plastic, wheels, and a clip-down lid that opens from either side according to the listing.

Clear sides help you find things without pulling every box out. A proper lid helps if the box will hold clothes rather than toys.

Fabric boxes on a wheeled frame

These pack down when empty, which is handy if you only need the storage in winter. The Somdot 48 L boxes (two pack) are listed at 78.5 x 43.5 x 17 cm each, with a zip lid, side handles and a frame with wheels. Fabric is lighter than rigid plastic but also softer: overfill it and it will sag.

When you should skip wheels

If clearance is very tight, wheels may be the difference between a fit and a miss. Our smallest-footprint pick on the main list is the SONGMICS under-bed bags, listed at only 15 cm tall, with a clear window and a Velcro divider. They slide rather than roll. IKEA’s SKUBB storage case (editorial link) is listed at 90 x 53 x 19 cm and folds flat when you do not need it.

If the floor is a thick, soft carpet, small plastic wheels can also be disappointing. In that case a rigid box with a smooth base, or a bag you lift by the handles, may be less frustrating than a wheeled unit that sinks.

Matching the box to what you will store

• Children’s toys and spare school kit: wheeled drawers or clear plastic boxes, so they can be pulled out without a fight. See also our Lego storage ideas if bricks are part of the load.
• Spare bedding and winter clothes: a larger lidded box such as the Smartstore, or vacuum bags plus a shallow bag, covered in under-bed storage for winter clothes.
• Shoes: a dedicated low organiser works better than a deep jumble, provided the height fits. Always measure pairs standing up.
• Things you rarely need: a bag or a lidded box at the far end of the bed is fine. Put the everyday box where you can reach it from the side you stand on.

Do not store anything that must stay completely dry in a damp spare room without checking the room first. Under a bed can be cooler and, in older houses, a little mustier than a wardrobe.

A short buying checklist

1. Write down clearance height, usable width and usable depth.
2. Subtract a little from the height for carpet and uneven floors.
3. Decide whether you need a lid, clear sides, or a furniture-like drawer front.
4. Check whether you want a pair (good under a single bed) or one large box.
5. Confirm wheels vs a slide, especially on thick carpet.
6. If children will use it, look for a handle they can grip and a weight they can move when the box is half full.

When you are ready to compare specific models, use the under-bed storage shortlist, which also flags a budget pick (vacuum bags) and the 15 cm-low bags for shallow frames.

FAQs

How much space do I need under the bed for storage?

Enough for the height of the box plus a little spare, measured to the lowest rail or slat, not to the mattress. If a box is listed at 18 cm, you want comfortably more than 18 cm of clear gap.

Is under-bed storage with wheels better than bags?

Wheels are better for things you reach often, and for children. Bags and low fabric cases are better when the frame is very low or when the box would only be moved twice a year.

Will under-bed drawers fit a single bed?

Often yes, but you must measure. The Libra drawers we compared are listed at 91 x 60 cm each; a pair is designed to use most of the space under a single bed. A shorter box may be needed if the bed has a central rail or existing drawers.

What if my bed is very low?

Look at the shallowest options first. On our list the SONGMICS bags are 15 cm tall. Skip bulky wheels unless the listing height still leaves a gap.

Can I use under-bed storage on a divan?

Only if there is an open cavity. Many divans are filled with their own drawers. In that case, use the existing drawers, or store overflow in a wardrobe or a cupboard instead.
