How Big Is a Sofa with Storage? Standard UK Sizes Explained

A sofa with storage is usually the same footprint as an equivalent sofa without it. Expect a two seater at around 150cm to 170cm wide, a three seater at 180cm to 220cm, and a storage corner unit at roughly 220cm to 280cm along the longest run. Depth typically sits between 85cm and 95cm, and overall height between 80cm and 90cm. The storage itself sits inside the base or under the seat, so it adds volume rather than external size.

What does change is the space you need around the sofa. A lifting seat needs clearance above, a drawer needs clearance in front, and both need somewhere for a person to stand while the compartment is open.

The three main types of sofa storage

Lift up seat bases

The whole seat section hinges upwards to reveal a deep compartment, often 25cm to 40cm deep across most of the sofa length. This gives the largest capacity and suits bedding, spare cushions and seasonal items.

You need around 60cm to 80cm of clear height above the seat to lift it comfortably, and nothing heavy sitting on top when you want to open it.

Under seat drawers

Drawers pull out from the base at floor level, usually 15cm to 20cm deep internally. Capacity is smaller but access is far easier for things you reach for regularly, such as remote controls, magazines and children’s toys.

Allow the full drawer depth plus standing room in front, which in practice means around 90cm of clear floor.

Storage within a chaise or corner

Corner sofas often place the storage in the chaise section, accessed by lifting the seat pad. This is the most generous option in terms of raw volume and works well in open plan rooms where cupboard space is limited.

Our modern corner sofas UK sale pages list the internal compartment sizes alongside the external dimensions, which makes it easier to judge what will actually fit inside.

Typical external sizes at a glance

A compact two seater with storage generally measures around 150cm wide, 88cm deep and 85cm high, with an internal compartment near 120cm by 60cm.

A standard three seater with storage sits closer to 200cm wide and 90cm deep, with internal space around 170cm by 60cm. That is enough for a full duvet set, several pillows and a folded throw.

A storage corner unit typically runs 240cm by 180cm overall, with the chaise compartment measuring roughly 100cm by 60cm. Sofa beds with storage often combine a smaller compartment with the mattress mechanism, so the usable volume is lower than the exterior suggests. You can see how the two functions are combined across our modern sofa beds UK sale collection.

Seat height rises slightly on some designs

Storage bases occasionally push the seat height up by two or three centimetres compared with a conventional frame, because the compartment floor sits above the base rails.

It is a small difference but worth noting if you are matching a sofa to an existing armchair, or if anyone in the household finds a higher seat easier or harder to use. Anything from 43cm to 48cm suits most adults.

How much can you actually store?

A three seater lift up base holds roughly the same as a large ottoman: think two duvets, a set of pillows and a few folded blankets. A pair of under seat drawers holds about the same as a shallow chest of drawers.

Weight is the limiting factor rather than volume. Gas lift mechanisms are rated for the seat and the mechanism, not for a compartment packed with books, so keep heavy items elsewhere and use the sofa for soft, bulky things.

For anything heavy or frequently accessed, a separate piece works better. A slim unit from our modern storage units UK sale range takes the load that a sofa base should not.

Measuring your room for a storage sofa

Start with the footprint, exactly as you would for any sofa: width, depth and the walkway around it. Allow 75cm for a main route through the room.

Then add the storage clearance. For a lift up base, check that a low ceiling, a sloped attic wall or a window sill will not block the seat from opening fully. For drawers, measure the distance from the sofa front to the coffee table and confirm the drawer can extend without moving furniture every time.

Finally, check the delivery route. Storage frames tend to be heavier than standard ones because the base is fully boarded, so a tight stairwell matters more than usual.

Does storage affect comfort?

Not if the sofa is well built. On a lift up design the cushion sits on a solid board rather than springs or webbing, so the seat relies entirely on the quality and depth of the foam.

Look for high resilience foam of reasonable thickness. A shallow cushion on a solid base feels firm quickly, which is the most common complaint about cheaper storage sofas. Drawer based designs usually keep conventional seat support above the drawers, so they feel closer to a standard sofa.

Which rooms benefit most

Storage sofas make most sense in flats, box rooms used as snugs, open plan living spaces without a hallway cupboard, and any room that doubles as an occasional guest bedroom.

They are also useful in family living rooms where toys need to disappear at the end of the day. A lift up base in the main sofa, combined with a footstool that opens, usually clears a room faster than any basket system.

In a period property with awkward alcoves, a storage sofa can avoid the need for an extra cabinet altogether, which keeps the floor plan simpler.

Practical points before you buy

Check whether the compartment is lined. An unlined chipboard interior can mark fabric over time, so a lining or a fabric bag for bedding is worth adding.

Confirm the lid support. A gas strut or a friction stay is safer than a lid held open by hand, particularly in a home with children.

Ask about ventilation if you plan to store bedding long term. Natural fibres need air, and a sealed compartment can leave textiles smelling stale. Airing the contents occasionally solves this easily.

Full internal and external measurements are published on each product page at Furniture in Fashion, so you can check the compartment against what you actually intend to keep in it before ordering.

Fitting a storage sofa into an awkward room

Alcoves either side of a chimney breast are the classic UK constraint. A two seater with storage often fits neatly into one alcove, while a three seater rarely will, so measure the alcove width at the narrowest point rather than at the opening.

Bay windows are another common situation. A storage sofa placed across a bay loses access to the compartment if curtains or a radiator sit behind it, so in that position drawers are usually the better option than a lift up base.

In a through lounge, the sofa often sits in the middle of the room. Here a drawer design keeps things simple, since a lifting seat means walking around to the front each time.

Organising the space inside

A large empty compartment quickly becomes a jumble unless it is divided. Fabric storage bags keep bedding sets together and make it possible to lift out one item without unpacking everything.

Vacuum bags are tempting for duvets, but they compress natural fillings hard and can leave feather and down flat for some time after unpacking. For long term storage of wool or down, a breathable cotton bag is kinder to the filling.

Label the bags on the side that faces upwards. It sounds fussy, but a labelled bag saves lifting a heavy seat twice when you are looking for spare pillows.

Keep anything used weekly in a drawer rather than under a lift up seat. Compartments that require moving cushions each time tend to go unused within a month.

How storage sofas compare with other options

An ottoman or blanket box offers similar volume in a smaller footprint, but it occupies floor space the sofa would take anyway, so a storage sofa is usually the more efficient use of a room.

Built in window seats hold more and look neat, though they are a fixed commitment and cost considerably more to install. A storage sofa moves with you.

A storage footstool sits between the two. Paired with a storage sofa it gives a second compartment at a lower cost, and it doubles as extra seating when people visit.

For households in flats without lofts or spare cupboards, combining the two often removes the need for an additional cabinet entirely, which keeps the room feeling open rather than lined with furniture.

Frequently asked questions

Is a storage sofa bigger than a normal sofa?

No. The external dimensions are broadly the same. The compartment uses space that would otherwise be empty inside the base.

How deep is the storage inside a sofa?

Lift up bases are commonly 25cm to 40cm deep. Under seat drawers are shallower, usually 15cm to 20cm.

Can I keep a duvet in a sofa storage compartment?

Yes, a three seater compartment typically holds a duvet, pillows and a couple of blankets. Air the contents from time to time.

Do storage sofas feel less comfortable?

Only when the foam is thin. Because a lift up seat rests on a solid board, cushion quality matters more than on a sprung frame.

How much space do I need in front of a storage drawer?

Around 90cm, which covers the drawer extension plus room to stand and reach inside without shifting the coffee table.
