How Much Storage Do You Actually Get in an Ottoman Bed?

Search this and you'll get answers ranging from 250 litres to over 1,200. One page says a standard double ottoman bed holds 450 to 650 litres. The next says a super king clears 1,000. Same beds, same UK sizes, wildly different numbers.

We make these bases, so here's the figure off the spec sheet. An ottoman base is a box the size of your bed. Ours are 22cm deep inside at the shallowest, and deeper across the rest of the range. On a double, 22cm gives you about 560 litres of storage space.

You won't fit 560 litres of stuff in it. That number measures an empty box to its edges, and nobody packs like that. You'll use around three quarters of it.

Still a lot of hidden storage. Just not the number you've been reading.

The short answer, size by size

Here's what 22cm gives you in each UK size. Treat it as the floor, not the ceiling.

Storage volume is the full cavity at 22cm deep. Usable capacity allows for the bed frame, the platform and the headroom you need to close the lid.

Deeper bases scale up. A 30cm cavity holds about a third more, so that double goes from 560 litres to nearer 770. That's where the big numbers online come from. A king size ottoman bed only passes 1,000 litres on an extra deep base. Quote a storage capacity without a depth attached and it means nothing.

In real terms, a double at 22cm swallows two winter duvets, a stack of pillows, three or four sets of bedding and a cabin case, with room to spare. A king takes all that plus a season of coats and jumpers.

How deep is it inside?

Most ottoman beds in the UK are 20cm to 26cm inside. Ours start at 22cm. Extra deep builds do exist at 30cm, 33cm, sometimes close to 40cm, but they're not what most people buy.

Here's the bit worth clearing up. Lots of guides claim a single gives 20 to 25cm, a double 25 to 30cm, a king 30 to 40cm. As if the box gets deeper as the bed gets wider.

It doesn't. Depth comes from how the base is built: the height of the sides, the thickness of the platform, whether there's a floor panel. A king and a single from the same range have the same depth. Only the footprint changes, which is why the king holds more.

Why the box is smaller than the maths

Width times length times depth works for an empty box. You're not storing an empty box. Four things eat into the usable space.

Base height isn't storage depth

You'll see a base listed at 30.5cm deep. That's the outside, floor to platform. Inside, you've got 22cm.

The missing 8cm is the timber, the platform your mattress sits on, and the way the lid drops onto the frame. Measure the outside, pack to the inside. If a listing only gives one figure, ask which one it is.

The inside is narrower than your mattress

The side rails sit in from the outer frame, so the storage area is a few centimetres tighter both ways.

Some bases have a rail down the middle. That splits the cavity in two, so anything long that would have gone in diagonally now won't fit at all. Ours are one open space for that reason.

Slats cost you a few centimetres

Sprung slats bow upwards and their fixings hang into the space below. You lose about 3cm against a flat solid platform.

That's a trade, not a fault. Slats flex under the mattress and let air through. A solid platform gives you a bigger box. Two bases at the same quoted depth won't hold the same if one is slatted.

You can't pack it to the rim

Anything above the internal edge stops the platform seating. A duvet stacked slightly high squashes down fine. A rigid box 2cm too tall doesn't.

Leave a gap anyway. Pack it solid and no air moves, which is how spare bedding starts to smell like a cupboard.

There's a weight limit too

This decides what goes in far more often than litres do.

The lifting mechanism works like the dampers on a car boot. Two gas struts take most of the weight as the bed lifts, hold the platform up while you've got both hands free, and slow it down on the way back.

Those struts are sized to lift your mattress, usually 40 to 60kg worth. Everything inside adds to what they're working against. Keep your stored items to around 45 to 50kg.

That sounds generous until you think about what's heavy. Duvets, pillows, coats and bedding are bulky and weigh nothing. You could fill a king base with soft goods and never get close. Books, tools, tinned food and free weights are the opposite. You'll hit the limit with the box half empty.

Do ottoman beds break easily? A well made one doesn't. Gas lift mechanisms are rated for tens of thousands of open and close cycles, and struts are a replaceable part when they finally tire, so replacement costs are a service job rather than a new bed. What kills them early is overloading. Ignore the weight limit and the lift gets heavy, the platform sits unevenly, and you're replacing struts years too soon. A base under that kind of strain usually creaks before anything actually fails, and while stopping a creaking bed is normally straightforward, it's worth treating as a warning here.

One more thing. Many ottoman bases have a canvas floor strapped to the frame rather than a solid board. It's fine for bedding. It's not a shelf. Heavy items want a boarded floor, or a corner where the frame takes the load.

So there are two answers. About 420 usable litres in a double, and about 45kg. Whichever you hit first is your limit, and a deeper base doesn't change the second one.

What actually goes in a double

A realistic load at 22cm:

• Two 13.5 tog duvets, folded not rolled
• Four to six pillows
• Three or four sets of bedding
• A cabin case lying flat
• A bag of seasonal clothes

That's most of it. Add another suitcase and you're done.

You'll see it claimed a king size ottoman holds 20 to 30 pairs of shoes. On volume, true. We'd still say don't. Shoes bring damp and dust into a sealed box with no airflow, and you'll smell it in the bedding within a season.

What won't fit: anything over about 20cm tall once it's in a storage box, anything rigid and awkward like a bike wheel or golf clubs, and anything you need at seven in the morning while someone's asleep on top of it.

End lift, side lift, half lift

The cavity is the same size either way. What changes is how much you'll actually use.

An end lift opens from the foot end, and you load it standing at the bottom of the bed. The far end, under the pillows, is a stretch. That third becomes where things go to be forgotten. Fine for a spare duvet. Not for anything else.

A side lift opens along one long edge, so everything stays within reach. If you plan to use the storage regularly, side lift bases are the ones to look at. They need clear floor down that side, which is awkward if the bed sits against a wall or hemmed in by bedside tables.

Either way you need somewhere to stand. About 30cm of clear floor on the opening side is the minimum. That measurement never appears on a dimensions chart, so check your room layout before you pick a lift direction.

Half lift bases only raise part of the platform. Lighter to open, and roughly half the storage you can reach. If maximum storage is why you're buying an ottoman, don't buy a half lift.

Vacuum bags roughly double it

Vacuum bags cut the volume of bedding and clothing by half to three quarters. Nothing else comes close. Two winter duvets that fill a third of a double base will squash into a corner.

One condition. Everything sealed in a bag has to be properly dry. Not warm-from-the-dryer dry. Actually dry. Bedding holds moisture you can't feel, and sealed in plastic in a dark box it has nowhere to go. Leave things out for a few hours after washing or ironing.

If you'd rather skip plastic, cotton or canvas bags are safer. You lose the compression, but air gets through.

What we'd keep out

An ottoman base sits flush to the floor, has no ventilation, and spends every night under two people giving off warmth and moisture. Great for dry, bulky items you don't need often. Poor for everything else.

Keep out damp gym kit, towels and shoes. Keep out washing that felt dry but hasn't aired. Keep out anything heavy. And keep out everyday items you need daily, because lifting a mattress every morning gets old fast.

Open it now and then even when you don't need anything. Five minutes with the platform up changes the air over and lets you spot damp early. Do it more often if your room runs cold or the windows stream in winter. That's most of what proper storage amounts to here.

Ottoman vs divan drawers

The ottoman wins on volume easily. Most divan beds with built in drawers are only 15 to 20cm deep inside the drawer, and the runners and drawer boxes take a chunk of the base before you've put anything in. Two drawers give you a fraction of the footprint. Four give you more, but you still can't lay anything across the middle.

You'll see it put as two to three times the storage, or up to four. Both are right, depending on whether you're comparing against a four drawer base or a two. An ottoman is one open space the size of the whole bed, which is where the difference comes from.

Drawer beds win on one thing. You get quick access one-handed, without moving a mattress, without waking anyone. For under bed storage you'll use weekly, built in drawers are more sensible. For putting things away for six months, lift up access is better. Storage aside, there's plenty more to weigh up between ottoman beds and divan beds, from how each one sits in a room to what happens when you move house.

The wardrobe comparison gets pushed too far. A wardrobe holds 600 to 800 litres, so a king ottoman is in the same bracket on paper. They do different jobs. A wardrobe hangs clothes and shows you everything at once. An ottoman stores flat, in layers, out of sight. Swap one for the other and you'll feel it the first time you go looking for a shirt.

What an ottoman genuinely replaces is the blanket box, the plastic crates under the bed and the overflowing airing cupboard. In small rooms that's the whole appeal: bedroom storage that needs no additional floor space and no extra furniture standing against a wall.

So is it enough?

For most people, easily. Around 420 usable litres in a double and 495 in a king is serious storage, and it's space saving in a way a chest of drawers or extra cabinets never will be.

Ignore the cost per litre comparisons, by the way. They always flatter the bed, because they price the box and quietly leave out whether you can reach into it or safely fill it.

An ottoman is at its best for bulky, soft, seasonal items. Spare bedding, winter coats, guest bedding, suitcases. Guest rooms especially, because everything the room needs twice a year lives inside the bed.

It's worst as a fix for a general storage shortage. Try to move books, files and half a wardrobe under there and you'll hit the weight limit, lose track of everything, and never see what's at the head end again. Going deeper won't help, because the limit you're hitting is weight, not volume.

And if you've got decent wardrobe space and just need somewhere for one spare duvet, don't change your bed over it. A blanket box does that job for far less money and effort.
