UK Bed & Mattress Sizes Chart

Small Single Bed (2'6" x 6'3" / 75cm x 190cm)

Best for: Toddlers, children, and guest rooms.

Great for kids’ rooms, narrow spaces, or bunk beds. Just enough wiggle room, with plenty of growing room. A small single is ideal when space is tight but comfort is still a priority.  For kids transitioning from a cot or for use in narrow rooms or bunk beds.

Single Bed (3' x 6'3" / 90cm x 190cm)

Best for: Teenagers, single sleepers, or small bedrooms.

Popular with teens, guests, and solo sleepers. Compact, practical, and perfect for smaller bedrooms. It offers a little more width than a small single while still being compact and space-saving.

Small Double Bed / Queen (4' x 6'3" / 120cm x 190cm)

Best for: Solo sleepers who want extra room or couples in tighter spaces.

Solo sleeper who likes space to starfish? Or a couple in a cosy flat? The small double is your sweet spot. It’s wider than a single, giving solo sleepers more space to stretch, but still compact enough for smaller bedrooms.

Double Bed (4'6" x 6'3" / 135cm x 190cm)

Best for: Couples or those who like more space alone.

The UK classic. A great everyday bed for couples or single sleepers who like to stretch out. The double bed is both practical and comfortable. It fits easily into most bedrooms and offers enough room for two average-sized adults.

King Size Bed (5' x 6'6" / 150cm x 200cm)

Best for: Couples who need extra space or taller individuals.

Need more legroom? Got pets or little ones sneaking in at night? A king bed gives you breathing room without overpowering your space.  A king size bed adds length and width, making it ideal for people who like to spread out or need extra legroom.

Super King Size Bed (6' x 6'6" / 180cm x 200cm)

Best for: Ultimate comfort seekers, families, or co-sleeping.

The luxury upgrade. Room for two, a toddler, and the cat. It's like sleeping on your own personal runway. The super king is the largest standard UK bed size – offering hotel-like comfort at home. Perfect for those who want maximum space or share the bed with kids or pets.

Why Mattress Size Matters

Getting the right mattress size isn’t just about fitting your bed frame – it’s essential for quality sleep. A mattress that’s too small can lead to disturbed sleep, discomfort, and even long-term aches and pains.

Here’s why mattress size makes a big difference:

• Comfort & Movement: Room to roll means deeper, more restful sleep – especially if you share the bed.
• Support That Fits: A mattress that suits your size supports your posture and helps ease pressure points.
• No Guesswork Fit: Our mattresses match UK bed frames exactly. No overhangs. No gaps. Just proper fit.
• Smart Use of Space: Choose the size that works for your room and your routine – not just what looks good online.

All our mattresses are made to UK sizing standards and pair perfectly with our handcrafted ottoman bed frames. That means better sleep, better storage, and no compromises.
