How to Shop for Beds Online with Confidence

To shop for beds online with confidence, focus on four things before you look at style: accurate room and access measurements, the full external dimensions of the frame, the type of base and slat system, and how the bed will be delivered and assembled. If those four points check out, the remaining decisions about colour, material and headboard shape become much easier, because you already know the bed will physically suit your home.

A good place to begin is our full range of modern beds UK sale, where you can filter by size and material. The steps below will help you narrow that choice to something you can order with certainty.

It also helps to keep the wider room in mind from the outset. Our modern bedroom furniture UK collection lets you check finishes across bedside tables, wardrobes and chests alongside the bed, which is useful if you want the room to feel coordinated once everything arrives.

Step one: measure more than the floor

Start with the room. Note the length and width, then mark the positions of the door, window, radiators, plug sockets and any built in furniture. Sketching a simple plan on paper takes a few minutes and saves a great deal of second guessing.

Next, mark out the bed’s footprint on the floor using masking tape or newspaper. Use the external dimensions of the frame, not the mattress size. Live with the outline for a day. Walk around it, open the wardrobe doors and pull out drawers. This simple exercise reveals problems that numbers on a screen can hide.

Finally, measure the delivery route: the front door, hallway turns, stairs, landings and the bedroom door. In older UK terraces, a tight turn at the top of the stairs is often the narrowest point.

Step two: read the dimensions properly

Product pages usually list several measurements, and it helps to know what each one means.

• Overall width and length. The full footprint of the frame, including the headboard and any side rails. This is the figure to use when planning your room.
• Mattress size. The size of mattress the bed is designed to hold. In the UK, a double is 135 by 190 cm and a king size is 150 by 200 cm.
• Headboard height. Measured from the floor. Check it clears window sills, wall lights and sloping ceilings.
• Base height or under bed clearance. Useful if you plan to store boxes beneath, or if you have a robot vacuum.
• Side rail height. Together with your mattress depth, this determines how high the sleeping surface sits.

If a listing does not show a measurement you need, such as headboard thickness, look for a dimension diagram among the product images. These often reveal details that the written specification leaves out.

Step three: understand materials and construction

Photographs show finish, but descriptions tell you what the bed is made of. Read them closely.

Wooden beds

Look for whether the frame is solid wood, engineered wood with a veneer, or a painted board. Each has its place. Solid timber can be sanded and refinished over time. Veneered frames offer the look of real wood with good stability. Painted finishes give a clean, uniform colour.

Upholstered beds

Note the fabric type: velvet, linen effect, chenille, bouclé or faux leather. Consider how each will suit your household. Pets and children are kinder to tightly woven fabrics than to loose weaves. Removable or wipeable finishes are worth noting if practicality matters.

Metal beds

Check the gauge of the frame and whether the slats are wooden or metal. A centre support rail with legs is a sign of good stability on larger sizes.

Step four: check the base and slats

The base matters as much as the frame. Sprung slats, which are gently curved, flex under weight and add a little give. Solid slats offer a firmer feel. Slat spacing affects how well the mattress is supported; many mattress makers recommend gaps of no more than around 7 to 8 cm, so check your mattress guidance.

Platform tops, as found on many ottoman beds, provide a solid surface with ventilation holes. Ensure there is airflow, since mattresses need to breathe.

If you are buying a new mattress at the same time, browse our mattresses UK alongside the frame so sizes and depths match. A very deep mattress in a frame with high side rails can make the bed taller than expected, while a thin mattress in a deep frame can leave the surface sitting below the rails. For a clear explanation of how frame, mattress and room sizes relate, our guide to UK king size bed dimensions is a useful reference, even if you are considering a different size.

Firmness labels vary from brand to brand. Our article on mattress firmness for UK buyers explains why labels can differ and what to consider when choosing.

Step five: judge colour and texture from a screen

Screens vary, and photographs are taken under studio lighting. A few habits help.

• Look at every image, including close ups and room shots. Room photographs often show colour more truthfully than cut outs on a white background.
• Read the colour name and description. Words such as warm, cool, mid or deep give useful context.
• Where fabric swatches are offered, request them and view them in your own bedroom at different times of day.
• Hold the swatch against your walls, flooring and existing furniture rather than judging it in isolation.

Step six: plan assembly

Most beds arrive flat packed or in a few large sections. Check how many boxes to expect and roughly how heavy they are. Read whether assembly requires two people and what tools are needed. Keep the box clear of the bedroom door until you are ready, and assemble the bed in the room where it will stay, since a finished frame may not fit through doorways.

Lay a blanket on the floor to protect both the flooring and the frame. Open boxes carefully without using sharp blades close to upholstery. Sort fittings before starting and tighten bolts gradually, then fully once the frame is square.

Step seven: think about the whole room

A bed rarely stands alone. Consider how it will work with bedside tables, wardrobes and lighting, and whether the frame’s finish sits comfortably with flooring and pieces you already own.

Think too about headboard height relative to bedside lamps and wall lights, and whether you need space for a bench or ottoman at the foot of the bed.

Step eight: check the practical details before you order

Before placing an order, read the product’s delivery information and the retailer’s returns policy. With us, Returns are available up to 30 days, and we offer free delivery to most UK mainland postcodes. Check whether delivery is to the door or to a room of choice, and make sure someone is at home who can help carry boxes if needed.

Keep a note of your order details and the product name so you can refer to them during assembly or if you have a question later.

Step nine: prepare the room before the bed arrives

A little preparation makes delivery day calmer. Strip and dismantle the old bed a day or two beforehand, and decide where it will go, whether that is a spare room, a friend’s house or a local reuse scheme. Vacuum the floor where the new frame will stand, since it is much harder to reach once the bed is in place.

Clear a path from the front door to the bedroom. Move rugs that might slide underfoot, lift pictures that hang low on stairwells and prop open doors that tend to swing shut. If you live in a flat, it is worth letting neighbours or the building manager know about the delivery, especially if a shared lift will be in use for a while.

Have the bedding for the new bed washed and ready. If the mattress is new and arrives rolled or vacuum packed, check the manufacturer’s guidance on how long to leave it to expand before sleeping on it. Planning the first night in advance turns the arrival of a new bed into something to look forward to rather than a rushed evening.

A short checklist

• Room measured and footprint marked out with tape
• Delivery route measured at its narrowest point
• External frame dimensions checked, not just mattress size
• Material and construction understood
• Slat type and spacing suit your mattress
• Mattress depth works with side rail height
• Colour checked in room photographs or with a swatch
• Assembly requirements known

Bringing it together

Buying a bed online becomes far less daunting when you treat it as a short sequence of checks rather than a single decision. Once the practical questions are answered, choosing the look you love is the enjoyable part. When you are ready, you can compare frames, materials and sizes across our full range at Furniture in Fashion.

FAQ

Should I use the mattress size or the frame size to plan my room?

Always use the external frame dimensions. Frames can be noticeably larger than the mattress, especially with padded headboards or wide side rails.

How can I be sure of a bed’s colour when buying online?

Look at room setting photographs, read the colour description carefully and request a fabric swatch where available. View it in your own room under daylight and artificial light.

Do I need to buy a new mattress with a new bed?

Not necessarily. If your current mattress is in good condition and matches the mattress size and slat spacing of the new frame, it can be used.

How many people are needed to assemble a bed?

Many beds require two people, particularly larger sizes and ottoman beds with gas struts. Check the product information before delivery day.
