A new bed has the power to transform far more than your sleep. It changes how a bedroom looks, how it functions and, perhaps most importantly, how it feels to live in every day. A bed that is too small can quickly become uncomfortable, particularly if you share it with a partner. One that is too large may dominate the room, leaving little space to move around or making the bedroom feel cramped despite careful decorating.

When you add hidden storage into the equation, choosing the right size becomes even more important.

An ottoman bed is not simply somewhere to sleep. It is also one of the largest storage solutions in the home, helping reclaim valuable space beneath the mattress that would otherwise go unused. Selecting the right size, therefore, isn't just about how much sleeping space you need. It is about balancing comfort, storage capacity, room proportions and the way you actually use your bedroom.

Whether you're furnishing a compact guest room, upgrading a master suite or buying your child's first "grown-up" bed, this guide explains everything you need to know about ottoman bed sizes and how to choose the one that is right for your home.

Why Size Matters More with an Ottoman Bed

People often choose a bed based purely on how it will look.

That is understandable.

The bed naturally becomes the focal point of the room, and its size influences everything from the proportions of the furniture to how luxurious the bedroom feels.

With an ottoman bed, however, size affects something else too:

Storage.

A larger bed doesn't simply provide more sleeping space. It also creates a significantly larger storage compartment beneath the mattress, giving you more room for spare bedding, towels, luggage, seasonal clothing and all the items that somehow never seem to have a permanent home.

This means your decision should consider two questions:

• How much sleeping space do you need?

• How much storage would genuinely improve your everyday life?

Small Single Ottoman Bed (75cm x 190cm)

The smallest standard UK bed size is often overlooked, yet it can be incredibly practical in the right setting.

A small single ottoman bed works particularly well where floor space is extremely limited, allowing children or occasional guests to enjoy a comfortable bed while still benefiting from valuable hidden storage underneath.

It is particularly suitable for:

• Toddler bedrooms

• Box rooms

• Small guest rooms

• Holiday homes

• Children's first bedrooms

The additional storage can comfortably accommodate spare bedding, toys, clothing or seasonal items without requiring extra furniture.

Single Ottoman Bed (90cm x 190cm)

The single ottoman bed remains one of the most versatile options available.

For children and teenagers, it offers generous sleeping space while making excellent use of the bedroom footprint. For guest rooms, it creates a practical solution that balances comfort with valuable hidden storage.

Because the storage compartment extends beneath the full mattress area, single ottoman beds often provide considerably more usable storage than parents initially expect.

Ideal for:

• Teenagers

• Guest bedrooms

• Student accommodation

• Children's rooms

Small Double Ottoman Bed (120cm x 190cm)

Sometimes referred to as a "three-quarter bed", the small double ottoman bed occupies a particularly useful middle ground.

It offers noticeably more sleeping space than a single bed without demanding the floor space of a standard double.

This makes it especially attractive for:

• Young professionals

• Solo sleepers

• Guest rooms

• Smaller master bedrooms

If you enjoy stretching out without completely dominating the room, this can be an excellent compromise.

Double Ottoman Bed (135cm x 190cm)

The double ottoman bed remains one of the UK's most popular choices.

For many couples, it provides a comfortable balance between generous sleeping space and practical room layout.

At the same time, the larger mattress footprint creates a substantial hidden storage compartment beneath the bed, making it particularly valuable for homes where wardrobe space feels limited.

Suitable for:

• Couples

• Main bedrooms

• Guest accommodation

• Family homes

For many households, a double bed represents the ideal blend of practicality and affordability.

King Size Ottoman Bed (150cm x 200cm)

If your bedroom allows, upgrading from a double to a king size ottoman bed often makes a surprisingly noticeable difference.

Those additional centimetres provide greater personal space, making it easier for couples to sleep comfortably without disturbing one another throughout the night.

The larger storage compartment also becomes increasingly useful for:

• Winter duvets

• Spare pillows

• Suitcases

• Seasonal clothing

• Family bedding

King size ottoman beds work particularly well in medium to larger master bedrooms where comfort is a priority.

Super King Ottoman Bed (180cm x 200cm)

For buyers seeking maximum comfort, a super king ottoman bed represents the ultimate choice.

The additional width creates an exceptionally spacious sleeping environment, particularly appreciated by couples, taller sleepers or anyone who simply enjoys more room to stretch out.

Naturally, it also provides the largest hidden storage compartment available within the standard UK range.

Perfect for:

• Luxury master bedrooms

• Larger homes

• Boutique hotel-inspired interiors

• Buyers prioritising comfort

Which Ottoman Bed Size Is Right for Your Room?

One of the biggest mistakes people make when buying a bed is focusing entirely on mattress size while forgetting about the room itself.

A bed should feel comfortably proportioned within the space.

As a general guide, try to leave around 60–75cm of clear walking space around the sides and foot of the bed wherever possible. This helps the room feel open and makes everyday tasks, such as changing bedding or accessing wardrobes, much easier.

Top Tip

Before ordering, use masking tape to mark the bed's footprint directly onto the floor. It is a simple but effective way to visualise how much space the finished bed will occupy.

Think Beyond Sleeping Space

Choosing a bed is rarely just about sleeping. Think about how the room functions throughout the year.

• Will the storage replace a chest of drawers?

• Could it free up wardrobe space?

• Will it eliminate the need for under-bed storage boxes?

The larger the ottoman bed, the greater the storage potential.

Sometimes choosing the next size up makes sense not because you need more room to sleep, but because you need somewhere to store life's everyday clutter.

Choosing the Right Mattress

Once you've chosen the correct bed size, selecting the right mattress becomes equally important.

Fortunately, ottoman beds work beautifully with a wide range of mattress types, including:

• Memory foam

• Pocket spring

• Hybrid mattresses

Choosing the right size

Choosing the right ottoman bed size is about far more than measurements on a specification sheet. It is about understanding how you live, how you sleep and how you want your bedroom to work for you over the coming years.

A thoughtfully chosen ottoman bed doesn't simply provide a comfortable night's sleep. It creates valuable storage, reduces clutter and helps transform the bedroom into a calmer, more organised space without asking you to compromise on style.

If you're still deciding, remember this simple rule:

Buy the largest ottoman bed your room can comfortably accommodate.

You'll rarely regret having a little more space to sleep or a little more room to store the things that make a house feel like home.
