Best Bed for a Spare Room: 7 Comfortable & Space-Saving Options

A spare room can be used as a guest bedroom, home office, study area, or even a storage space. The right bed should fit the room without making it hard to move around. It should also give your guests a comfortable place to sleep.

So, what is the best bed for a spare room? For a room used mainly as a guest bedroom, a standard double is a good all-round choice. If the room is smaller, a small double or single bed can leave more useful floor space. For rooms with more than one purpose, a sofa bed, day bed, or folding bed may work better.

Before buying, think about room dimensions, how often guests stay, whether couples will use the room, and how much storage space you need. A bed that looks good in a showroom may not be the right choice once you add a wardrobe, desk, bedside table, and walking space.

Which Bed Is Best for a Spare Room?

There is no single bed that suits every spare room. Your choice should match the size of the room and the people who are most likely to use it.

If guests stay often, a proper guest bed frame with a good mattress will usually give better long-term comfort than a temporary option. If overnight guests are rare, you may get more value from a bed that can be folded or used for another purpose.

7 Best Beds for a Spare Room

1. Standard Double Bed — Best for a Dedicated Guest Room

A standard double bed is one of the safest choices for a dedicated guest bedroom. It gives two adults enough sleeping space without taking up as much room as a king size bed.

It is especially useful if couples regularly stay with you. A double guest bed also gives a spare room a more traditional bedroom feel, so guests do not have to sleep on a converted sofa or temporary mattress.

The main thing to check is the bed footprint. The mattress size is only part of the space the bed will use. The complete bed frame may be wider or longer, especially if it has a large headboard or thick side rails.

A standard double is therefore best when you have enough walking space around it and can still open wardrobes and doors easily.

2. Small Double Bed — Best for Smaller Spare Rooms

A small double bed can be a smart middle ground when a single feels too small but a standard double takes up too much floor space.

It can work well for one adult and can also accommodate two people for shorter stays. This makes it useful in a small spare room where every bit of floor space matters.

Before buying, measure the whole bed rather than relying only on the advertised mattress dimensions. Leave enough room to walk around the bed and access other furniture.

For many homeowners, a small double is one of the most practical space-saving guest bed options because it keeps reasonable sleeping space without filling the entire room.

3. Single Bed — Best for One Guest

If your spare room is mainly used by one person at a time, a single bed may be all you need.

A single bed takes up much less space than a double, leaving room for a wardrobe, desk, chair, or chest of drawers. It can also be a good choice for children, grandchildren, or a friend staying for a few nights.

You can make a single more useful by choosing one with a trundle or under-bed storage. A trundle can provide another sleeping surface when needed, while drawers can hold spare bedding or towels.

For a narrow room, a single bed can also make it easier to create a clear path between the door and other furniture.

4. Divan or Ottoman Bed — Best for Extra Storage

If your spare room lacks cupboards, a bed with storage can solve two problems at once.

A divan can have storage drawers underneath, while an ottoman bed usually provides a larger storage area beneath a lifting base. This space can be useful for bedding, blankets, towels, seasonal items, or guest luggage.

An ottoman bed is worth considering when you have limited cupboard space but still want a full-size sleeping surface. A divan can be easier to organise if you prefer separate drawers.

However, storage should not be your only consideration. Make sure the bed has a suitable base and that the mattress provides enough mattress support for comfortable sleep.

Also check whether there is enough room beside the bed to open drawers or lift the ottoman base without hitting another piece of furniture.

5. Sofa Bed — Best for a Multi-Purpose Spare Room

A sofa bed is useful when your spare room needs to do more than provide a place for overnight guests.

For example, you may use the room as a home office or study during the week and turn it into a guest room when family or friends visit. A sofa bed gives you seating during the day and a sleeping surface at night.

The important point is comfort. Not every sofa bed is designed for frequent sleeping, so check the mattress construction and support before buying.

If adults will use it regularly, look for a proper sleeping surface rather than choosing based only on how the sofa looks.

A sofa bed can be a strong guest bedding solution when space is limited, but it may not be the best option for guests staying for a week or longer.

6. Day Bed — Best for Flexible Small Spaces

A day bed is another useful option for a room that has more than one purpose.

It can look like a sofa during the day but provide a proper sleeping area at night. Some designs also include a pull-out section, giving you an extra sleeping surface without keeping two full beds in the room.

This makes a day bed useful for guest beds for small spaces, especially when you want the room to feel like a normal living or working area between visits.

A day bed can also make a narrow room feel less like a traditional bedroom because its design often works well against a wall.

Just check the sleeping dimensions before buying. Some day beds are based around a single mattress, while others can provide a larger sleeping area.

7. Folding or Rollaway Bed — Best for Occasional Guests

If you only have occasional guests, you may not want a permanent bed taking up valuable floor space all year.

A folding bed or rollaway bed can be stored when it is not needed and brought out when visitors stay. This makes it useful for last-minute visitors, short stays, or a room that has another main purpose.

A good folding guest bed should be easy to move, simple to store, and stable when opened. The mattress also matters because a thin sleeping surface may not provide enough support for some adults.

For regular overnight use, a permanent bed will usually be more comfortable. But for temporary sleeping space, a folding bed can be a practical solution.

What Size Bed Is Best for a Spare Room?

The right bed size depends on the room and who will sleep in it. Bigger does not always mean better if the bed leaves little usable space.

A single guest bed is usually enough for one adult or child. A small double offers more sleeping room while taking less space than a standard double. If couples regularly stay overnight, a standard double is generally a better choice.

A king size guest bed can provide more sleeping space, but it needs a larger room. There is little point choosing a king if it blocks the wardrobe, makes the door difficult to open, or leaves no comfortable route around the room.

When measuring, look at both the UK bed sizes and the overall dimensions of the frame. A headboard, footboard or wide side rails can increase the amount of space required.

Also consider:

• Room dimensions

• Wardrobe position

• Door clearance

• Window access

• Bedside table space

• Walking space

• Overall frame dimensions

• Existing furniture

The aim is to create a room where guests can sleep comfortably without making the rest of the room difficult to use.

What Is the Best Bed for a Small Spare Room?

For a small room, the best choice is usually the one that gives enough sleeping space while keeping the rest of the room usable.

A small double is a strong option when you want more room than a single without using the full footprint of a standard double. For one guest, a single bed may be the better choice.

If the room also works as an office or study, consider a sofa bed or day bed. For guests who only visit a few times each year, a folding or rollaway bed can be stored away between visits.

Storage can also make a small room easier to manage. An ottoman or divan can use otherwise wasted space underneath the bed for bedding and luggage.

Before choosing any space saving guest beds, measure the room with the other furniture in place. A bed that technically fits may still make the room feel cramped if there is not enough space to walk around it.

What Is the Best Bed for Occasional Guests?

For occasional guests, you do not always need a permanent bedroom-style bed.

A folding bed is useful if you have somewhere suitable to store it. A sofa bed or day bed is better when you want the room to have a second purpose throughout the year.

An air bed can work for very short or unexpected stays, but it is usually less suitable when guest comfort is a priority. It may also feel less stable and supportive than a proper bed and mattress.

Think about how often the bed will actually be used. If family members visit every few weeks, investing in a comfortable permanent bed may make more sense. If you only host overnight visitors a few times a year, a temporary bed can save valuable floor space.

What Mattress Is Best for a Spare Bedroom?

The bed frame gives you the structure, but the mattress has a bigger effect on how comfortable your guests feel. Because you may not know whether your visitors sleep on their side, back or front, a mattress with a balanced feel is usually the safest choice.

A medium-firm mattress is a practical starting point for a guest room. It can offer a useful mix of mattress support and comfort for different sleepers without feeling extremely hard or soft.

Pocket Sprung Mattress

A pocket sprung mattress can be a good choice when you want support, airflow and a more traditional mattress feel. The individual springs can also help reduce movement across the sleeping surface.

Memory Foam Mattress

A memory foam mattress can provide good pressure relief and mould around the body. It may suit guests who prefer a softer, more cushioning feel, although some people may find foam warmer than a spring-based mattress.

Hybrid Mattress

A hybrid mattress combines springs with foam or other comfort materials. It can be worth considering when you want a balance between support, pressure relief and airflow.

For a guest bedroom, don't focus only on firmness. Think about sleeping position, body type, temperature and the needs of different sleepers. A mattress should also be suitable for the chosen bed base.

If storage is important, a rolled mattress can make delivery and handling easier, but always check the manufacturer's instructions before using it on your chosen frame.

What Bed Frame Is Best for a Guest Room?

The best bed frame depends on the style of your room, how often guests stay and how much maintenance you want.

Wooden Bed Frame

A wooden bed frame works well in traditional and modern bedrooms. Pine can be a more affordable choice, while oak can give the room a heavier, more classic look.

Wooden frames are also available with different finishes, so they can be matched with wardrobes and other bedroom furniture.

Metal Bed Frame

A metal frame can suit a simple or modern guest room. It can also be a practical option when you want a lighter-looking bed that does not visually dominate a small room.

Fabric or Upholstered Bed Frame

A fabric bed frame can give a guest bedroom a softer appearance. Upholstered designs are available in materials such as linen or velvet and can work well when the bed is the main feature of the room.

Whatever material you choose, check the construction underneath the mattress. A strong slatted base, suitable bed slats and well-supported side rails can all affect how the mattress performs.

If you prefer a more traditional setup, a divan base can also be worth considering. The key is to match the base with the mattress rather than choosing the frame on appearance alone.

How to Match a Bed to Your Spare Room

Instead of choosing a bed simply because it looks good, start with the way you use the room.

For example, if your spare bedroom has a desk and wardrobe, putting a large bed in the centre may leave the room difficult to use. A space-saving guest bed could give you a better balance.

If guests stay regularly, put more weight on comfort. If the room is mostly an office, storage area or study, flexibility may matter more.

This is where a retailer such as The Bed Boss can be useful when comparing different bed styles, sizes and room requirements before making a purchase.

How to Make a Spare Room Comfortable for Guests

Choosing the right bed is only the first step. Small details can make a spare room much more comfortable without requiring a major redesign.

Start With the Mattress

A supportive guest bed mattress should be the first priority. There is little benefit in buying an attractive frame if the mattress is uncomfortable.

Provide Comfortable Bedding

Use clean sheets, a suitable duvet and pillows with enough support. Keep an extra blanket nearby if the room can become cold at night.

Add a Mattress Protector

A mattress protector helps keep the mattress cleaner between visits. This is particularly useful when different guests use the same bed throughout the year.

Give Guests Somewhere to Put Their Things

A small bedside table, shelf or luggage area can make a big difference. Guests should not have to leave bags on the floor or search for somewhere to place their phone and glasses.

Keep Access Clear

Don't place furniture where it blocks the door or makes it difficult to reach the wardrobe. Good walking space is just as important as the bed itself.

For older guests, also consider the height of the bed and how easy it is to get in and out. A comfortable guest room should be practical, not just attractive.

Frequently Asked Questions

How much space should you leave around a spare room bed?

Leave enough walking space for guests to get in and out of bed and reach the wardrobe, door and other furniture comfortably. The exact amount depends on the room layout, so measure the complete bed frame and surrounding furniture before buying.

Should a spare room bed be the same size as your main bedroom bed?

Not necessarily. A spare room may need a smaller bed because it has less floor space or needs to double as an office, while a dedicated guest bedroom may have enough room for a standard double or larger bed.

Is it better to prioritise the bed or storage in a small spare room?

Sleeping comfort should come first, but storage can be very useful when cupboard space is limited. An ottoman or divan with under-bed storage can give you both a proper sleeping surface and somewhere to keep bedding or luggage.

Can a spare room bed be comfortable for different types of guests?

Yes, but the mattress is important because different guests can have different sleeping positions, body types and firmness preferences. A supportive medium-firm mattress is often a sensible starting point when you need a bed that suits a range of sleepers.

What should you check before buying a guest bed online?

Check the overall frame dimensions, mattress size, room measurements, weight capacity and mattress compatibility before ordering. Also look at assembly requirements, storage mechanisms, delivery information and the retailer's returns or warranty terms.

Conclusion

The best bed for a spare room depends on how you plan to use the room.

For a dedicated guest bedroom, a standard double bed is usually the best all-round option, particularly when couples may stay. If floor space is limited, a small double bed can offer a useful balance between comfort and room size.

For one guest, a single bed can leave more space for other furniture. If storage is a problem, an ottoman bed or divan can turn the unused space underneath the mattress into useful storage.

For a room that has another purpose, such as an office or study, a sofa bed or day bed can provide more flexibility. And when guests only stay occasionally, a folding bed or rollaway bed can be stored away when the room is being used for something else.

Most importantly, don't choose a bed by size or appearance alone. Measure the room, consider who will use it, check the full frame dimensions, and choose a mattress that provides reliable support.

A well-planned spare room does not need to be large. With the right combination of bed size, mattress comfort, storage and usable floor space, even a small room can give overnight guests a comfortable place to sleep.
