What Do You Need From Your New Bed?

Before choosing a style, think about what matters most to you. These four questions can help narrow down your options.

What Size?

Choose a size that gives you enough sleeping space without overwhelming your bedroom.

What Type?

Compare divan beds, bed frames and ottoman beds to find the right solution.

Need Storage?

Make use of the space underneath your bed with drawers or ottoman storage.

What Style?

Finish your bedroom with a headboard and bed design that suits your décor.

When Should I Replace My Bed?

Knowing when to replace your bed isn't just about how it looks. Over time, a bed frame or base can experience wear and tear, while your sleeping requirements may also change.

Visible Wear & Tear

Sagging, broken components, damaged upholstery or structural issues can indicate your bed is past its best.

Reduced Comfort

If your current bed no longer feels comfortable or supportive, it could be time for an upgrade.

Difficulty Getting Comfortable

Regular tossing and turning may be a sign that your current bed and mattress no longer meet your needs.

Your Bedroom Has Changed

Moving, redecorating or needing additional storage can all be good reasons to choose a new bed.

Your Mattress Needs Replacing

If you're buying a new mattress, make sure your existing bed base is suitable and in good condition.

Don't forget the mattress. When replacing your bed, it's important to consider the bed and mattress together. Read our Mattress Buying Guide →

What Bed Size Should I Choose?

Choosing the right bed size is one of the most important decisions when buying a new bed. Consider who will use it, how much sleeping space you prefer and how much room you have available.

Small Single
75 × 190cm · 2'6" × 6'3"

A useful choice for children's bedrooms, compact rooms and guest spaces.

Single
90 × 190cm · 3'0" × 6'3"

Ideal for one person and popular for children's, teenagers' and guest bedrooms.

Small Double
120 × 190cm · 4'0" × 6'3"

More sleeping space than a single while taking up less room than a standard double.

Double
135 × 190cm · 4'6" × 6'3"

A popular choice for couples and spacious single sleepers.

King Size
150 × 200cm · 5'0" × 6'6"

Offers additional width and length for a more spacious night's sleep.

Super King
180 × 200cm · 6'0" × 6'6"

The largest standard UK bed size, ideal for couples wanting plenty of sleeping space.

TOP TIP: Measure the overall dimensions of the bed frame, not just the mattress. Headboards, footboards and storage mechanisms can increase the total footprint.

Which Divan Storage Option Should I Choose?

Drawer Storage

Continental Drawers

Combines different drawer sizes to maximise storage while leaving room for a bedside table.

How Do I Choose the Right Bed Height?

Bed height affects both the appearance of your bedroom and how easy the bed is to get in and out of. The overall height depends on the bed frame or base, feet and mattress thickness.

Your Height

Choose a height that allows you to sit down and stand up comfortably.

Mattress Depth

A deeper mattress will increase the overall height of your finished bed.

Bedroom Style

Higher beds can feel substantial, while lower beds can create a minimalist look.

Storage

The height of the base can affect available clearance underneath the bed.

Upholstered

Upholstered headboards offer softness and are available in a wide range of fabrics, colours and designs.

Wooden

Wooden headboards provide a classic appearance and work well with traditional and contemporary bedrooms.

Metal

Metal headboards are available in modern and traditional designs and are relatively easy to maintain.

Floor Standing

Floor-standing headboards extend to the floor and can create a striking bedroom focal point.

Strutted

Strutted headboards attach to the bed using struts and offer a practical finishing touch.

Check Compatibility

Always check the headboard size, fixing method and compatibility with your chosen bed.
