King Size Divan Bed UK: The Complete Buying Guide (2026)
A king size divan bed is one of the most popular choices for UK bedrooms — and for good reason. Measuring 150 x 200 cm (5ft x 6ft 6in), a king size bed gives couples or solo sleepers generous space, while a divan base adds practical under-bed storage that a standard bed frame simply cannot match. Whether you're upgrading from a double or replacing a worn-out set, this guide covers everything you need to make the right choice.
What Is a Divan Bed?
A divan bed is a bed that uses a solid, upholstered base — rather than a slatted or wooden frame — to support the mattress. The base is typically split into two halves for easier transportation and can be fitted with built-in storage drawers or a top-opening ottoman lift. Divan beds are a UK staple: they're firmer, more supportive, and far more storage-savvy than continental-style bed frames.
Unlike a bed frame, a divan base works as part of the mattress's suspension system. This means your mattress lasts longer and performs better when paired with its matching divan base.

King Size Divan Bed Dimensions: What You Need to Know
Before buying, always measure your bedroom. A standard UK king size divan bed is 150 cm wide x 200 cm long (approximately 5ft x 6ft 6in). Allow at least 60–90 cm of clearance on each side for comfortable movement, and ensure doors and wardrobes can open freely.
- King Size (5ft): 150 cm x 200 cm — ideal for couples needing generous sleeping space
- Super King (6ft): 180 cm x 200 cm — the most luxurious option for spacious master bedrooms
- Small Double (4ft): 120 cm x 190 cm — a space-saving step up from a single

King Size Divan Bed Storage Options
One of the biggest advantages of a divan base is built-in storage. Here is a breakdown of the main configurations available:
Standard Drawers
The most common option. Drawers are typically fitted into the sides of the divan base — you can choose 2 drawers (one per side), 4 drawers (two per side), or even a combination of side and foot-end drawers. Drawers are ideal for bedding, seasonal clothing, or everyday essentials. They slide out easily and do not require lifting the mattress.
Ottoman Lift Storage
An ottoman divan base features a gas-lift mechanism that raises the entire mattress to reveal a deep storage compartment underneath. This gives significantly more storage volume than standard drawers — often enough for duvets, pillows, and suitcases. Our Gas Lift Ottoman Bed guide explains exactly how this mechanism works and who it suits best.
No Storage (Base Only)
If you have adequate storage elsewhere in your bedroom, a plain divan base with no drawers is the most affordable option and still delivers the firmness and mattress support that divan beds are known for.
Choosing a Mattress for Your King Size Divan Bed
Most king size divan beds are sold as a set — base plus mattress — though you can also buy the base alone. Choosing the right mattress type is just as important as choosing the base. The main options are:
Pocket Sprung Mattresses
Pocket sprung mattresses use individual fabric-encased springs that move independently. This means the mattress contours to each person's body shape, reducing motion transfer — ideal for couples. Spring counts typically range from 1,000 to 3,000 springs in a king size. Higher spring counts generally mean a more responsive, supportive feel. Read our Complete Guide to Pocket Sprung Mattresses for everything you need to know.
Memory Foam Mattresses
Memory foam moulds to your body, distributing weight evenly and relieving pressure points. It is a popular choice for those with joint pain or back issues. For a detailed side-by-side comparison, see our article: Pocket Sprung vs Memory Foam — Which Is Right for You?
Orthopaedic Mattresses
Orthopaedic mattresses are firmer than standard options and are designed to provide extra lumbar support. They are particularly recommended for back pain sufferers. According to the Sleep Foundation, a medium-firm mattress is generally the best choice for chronic back pain, as it supports spinal alignment without being uncomfortably hard.
Headboard Options for King Size Divan Beds
Divan bases are sold without a fixed headboard, giving you complete freedom to choose the style that suits your bedroom. Headboards attach to a divan base via two metal struts that slot into pre-drilled holes on the back of the base. The most popular styles for UK bedrooms include:
- Panel headboards: A clean, rectangular design — available in fabric, velvet, faux leather, and wood finishes
- Wingback headboards: Feature side wings for a high-end, boutique hotel look. Ideal for making a statement in a large master bedroom
- Chesterfield headboards: Deep button-tufted upholstery in velvet or faux leather for a glamorous, vintage aesthetic
- Ottoman headboards: Feature hidden storage inside — a clever space-saving option
According to Real Homes, choosing a headboard that is at least 10–15 cm wider than your mattress creates the most balanced, proportional look in your bedroom.
King Size Divan Bed Fabrics and Finishes
UK divan beds come upholstered in a range of fabrics:
- Plush velvet: Luxuriously soft, available in jewel tones (midnight blue, emerald, burgundy, silver) — a popular choice for statement bedrooms
- Chenille: A textured, durable weave that adds warmth and depth
- Linen-look fabric: Clean and contemporary — works well in Scandi or minimalist interiors
- Faux leather / PU leather: Wipe-clean and hardwearing — suited to modern or industrial bedroom styles
What to Look for When Buying a King Size Divan Bed: A Checklist
- Measure your room carefully — a king-size bed needs at least 3.5 m x 3.5 m of clear floor space to feel comfortable
- Decide on storage needs — do you need drawers, ottoman lift, or both?
- Choose your mattress firmness — soft for side sleepers, firm for back sleepers, medium for most couples
- Check spring count — for a king size, aim for a minimum of 1,500 springs for good support
- Consider the fabric — choose a colour and material that complements your bedroom decor
- Check delivery options — good UK retailers offer room-of-choice delivery and old bed removal
According to Which?, the most important factor when choosing a bed is getting the mattress firmness right for your sleep position — more so than the base type or brand name.

Frequently Asked Questions About King Size Divan Beds
What is the size of a king size divan bed in the UK?
A standard UK king size divan bed measures 150 cm wide x 200 cm long (5ft x 6ft 6in). The base is usually delivered in two halves and bolted together in your bedroom for ease of access through doorways and up stairs.
Are king size divan beds good for back pain?
Yes — when paired with the right mattress. A divan base provides a firm, even surface that supports the mattress properly. Pair it with a medium-firm pocket sprung or orthopaedic mattress for the best lumbar support. See our guide: Best Mattress for Back Pain UK.
Do I need a box spring with a divan bed?
No — the divan base itself acts as the foundation for your mattress. Box springs are an American concept not commonly used in the UK. A divan base provides all the support and tension your mattress needs.
Can I use any mattress on a divan base?
Yes, any standard UK king size mattress will fit a matching divan base. For the best performance and longevity, choose a mattress designed to work with a firm divan edge — many manufacturers sell matched divan and mattress sets for this reason.
What is the difference between a divan bed and an ottoman bed?
A divan bed typically uses side or foot-end drawers for storage. An ottoman bed uses a gas-lift mechanism to raise the entire mattress platform, revealing a large under-bed storage compartment. Read our full comparison: Ottoman Bed vs Divan Bed — Which Is Right for You?
