Upgrading to a king size bed is one of the most noticeable improvements you can make to a bedroom. More sleeping space, a stronger visual presence in the room, and in many cases, built-in storage that replaces separate bedroom furniture entirely. The right king size bed frame makes a bedroom feel genuinely complete rather than functional.
Whether you’re after a budget king size bed with clean gas lift storage, a king size ottoman bed with a hydraulic mechanism, a floating platform king bed with RGB lighting, or a super king size bed with wireless charging built in, this list covers every need. Every pick is from Aosom, each one genuinely different in design, mechanism, and purpose.

The Best King Size Beds – Reviewed
1. King Size Gas Lift Bed – Tufted Upholstered Headboard, Platform Base
Best for: Buyers who want a straightforward king size storage bed without extra features or a high price.
Not every king size bed needs to come loaded with LED lighting and charging ports. Sometimes the right choice is a clean, well-built gas lift storage bed that does what it needs to do without unnecessary additions. This king size platform base opens on a smooth gas lift mechanism to reveal full-width storage beneath the mattress, generous enough for duvets, seasonal clothing, pillows, and anything else that would otherwise end up in bags at the back of a wardrobe.
The tufted headboard gives it a structured, upholstered finish that looks considerably more expensive than the price suggests. The platform base is stable and firm without requiring a separate slat kit, and the overall build handles daily use without the bulk of more feature-heavy alternatives.
Key Features:
- King size (5ft), fits a 150x200cm mattress.
- Gas lift mechanism, smooth single-action full-width storage opening.
- Tufted upholstered headboard, structured and premium-looking.
- Platform base, no separate slats needed.
- Most affordable king size storage bed on this list.
Pros:
- Gas lift delivers the full storage benefit without the cost of a hydraulic multi-piston system.
- Tufted headboard gives a polished finish at the entry-level king price point.
- The platform base provides a stable sleeping surface without additional accessories.
Cons:
- No LED lighting or charging station, purely a storage-focused design.
- Gas lift piston is single-point, heavier mattresses may require more effort to open over time.
2. King Ottoman Bed – Storage Drawer, Adjustable Headboard, Black
Best for: King size bedrooms that need two separate storage mechanisms in one frame.
Most king size storage beds give you one mechanism, either a lift or a drawer. This black ottoman frame gives you both. The full ottoman base lifts to reveal the large under-mattress cavity for bulkier seasonal items, while the wheeled side drawer provides a second, quickly accessible storage zone for everyday items like books, chargers, and remotes without lifting the mattress at all.
The adjustable headboard lets you set the angle to suit sitting up in bed comfortably, a feature that fixed headboards simply cannot offer. The black finish suits contemporary, dark-cabinetry, and industrial-influenced UK bedroom styles particularly well.
Key Features:
- King size (5ft), dual storage: ottoman lift + wheeled side drawer.
- Adjustable headboard, multiple angle positions for sitting up in bed.
- Black upholstered finish, contemporary and versatile.
- Wheeled side drawer for everyday accessible storage.
- The Ottoman base reveals a full king-width storage cavity.
Pros:
- Dual storage mechanism covers both bulk seasonal storage and everyday accessible items in one frame.
- Adjustable headboard provides sitting-up comfort that fixed alternatives cannot replicate.
- Black finish suits dark-toned UK bedroom interiors that lighter options don’t complement.
Cons:
- The side drawer reduces the total width of the ottoman cavity slightly compared to single-mechanism alternatives.
- Black finish shows dust more readily than grey or beige alternatives.
3. King Size Hydraulic Bed with LED Lighting and Charging Station – Grey
Best for: Modern king size bedrooms that want hydraulic storage, ambient LED lighting, and charging built in.
A hydraulic lift king size bed at this price with LED base lighting and a built-in charging station is genuinely hard to find in the UK. The hydraulic pistons distribute the mattress weight evenly across multiple points, giving a smoother, more balanced lift than a single gas piston, and the full king-width storage cavity handles a significant volume of household storage once opened.
The LED lighting runs along the base, creating ambient illumination that makes a genuine difference to the bedroom atmosphere in the evening. The charging station in the headboard keeps devices powered at the bedside without trailing cables across the floor or nightstand.
Key Features:
- King size (5ft), hydraulic multi-piston lift storage.
- LED base lighting, adjustable ambient illumination.
- Built-in charging station in the headboard.
- Grey upholstered headboard, clean and contemporary.
Pros:
- Hydraulic multi-piston mechanism opens more smoothly and evenly than single gas lift alternatives.
- LED base lighting and charging station add genuine daily value that plain storage beds cannot offer.
- Grey finish works across most contemporary UK bedroom colour schemes without clashing.
Cons:
- Grey is the only colour option, not suited to warmer or bolder bedroom schemes.
- Charging station requires proximity to a wall socket, plan bedroom layout before assembling.
4. King Size LED Hydraulic Bed with Charging Station and Adjustable Tufted Headboard
Best for: King size bedrooms that want hydraulic storage, LED lighting, and a headboard that adjusts for comfort.
The adjustable tufted headboard is what separates this from the hydraulic LED king bed above. While both share hydraulic storage and LED lighting, this one allows you to change the headboard angle, which makes a meaningful practical difference if you regularly sit up in bed to read, watch TV, or work. The button tufting adds visual texture and a more considered aesthetic than plain upholstered alternatives at the same price.
The hydraulic lift opens the full storage base smoothly, and the LED lighting and charging station match the tech specification of the best king size beds at significantly higher price points. The overall dimensions at 206L x approximately 161W cm suit most standard UK master bedrooms without requiring oversized wall clearance.
Key Features:
- King size hydraulic lift storage, full base cavity opens on multiple pistons.
- Adjustable tufted headboard, angle-adjustable for sitting up in bed.
- LED lighting along the base.
- Built-in charging station.
- Button-tufted headboard surface, textured premium finish.
Pros:
- Adjustable headboard covers sitting-up comfort that fixed-headboard hydraulic beds on this list cannot.
- Button tufting adds visual texture that plain upholstered alternatives lack at this price.
- Combines hydraulic storage, LED, and charging in one frame without a premium price.
Cons:
- Adjustable headboard mechanism adds complexity, check hinge quality before purchasing.
- Button-tufted headboard has more visual texture but slightly more care than plain upholstered alternatives.
5. King Size Floating Platform Bed with RGB LED and Charging Station – Grey
Best for: Design-forward UK bedrooms that want a floating platform aesthetic with RGB lighting.
Floating platform beds, frames where the base is recessed to create the visual impression the mattress hovers above the floor, have become one of the most popular contemporary bedroom looks in the UK. This grey upholstered king size version brings that visual effect together with RGB LED lighting and a built-in charging station at a price that makes the feature combination genuinely accessible.
The RGB lighting is adjustable in colour, giving you genuine control over the bedroom atmosphere rather than a fixed tone. Unlike the hydraulic options on this list, this is a platform frame without a storage lift, making it the right choice for buyers who prioritise design and lighting over storage capacity.
Key Features:
- King size (5ft), floating platform frame design.
- RGB LED lighting, adjustable colour settings.
- Built-in charging station in the headboard.
- Grey upholstered finish, soft and contemporary.
- Rated 4.8 stars by verified buyers.
Pros:
- Floating platform design creates a contemporary visual effect unavailable on standard frame beds.
- RGB LED adjustable colours give atmosphere control that fixed-tone lighting cannot replicate.
- 4.8-star rating confirms build quality and design satisfaction across verified buyers.
Cons:
- No under-bed storage mechanism, the platform design prioritises aesthetics over storage capacity.
- A floating platform sits lower to the floor than traditional frames, may not suit those who prefer a higher sleeping position.
6. King Size Hydraulic Bed with Wheeled Drawer and Velvet Adjustable Headboard – Grey
Best for: King size bedrooms that want velvet upholstery, hydraulic storage, and a side drawer combined.
Velvet upholstered king size beds have become one of the most sought-after finishes in UK master bedrooms, and this grey velvet frame combines that premium material with a hydraulic lift storage base and a wheeled side drawer. The result is a bed that covers three distinct needs at once: the warmth and texture of velvet, the full-capacity hidden storage of a hydraulic lift, and the quick everyday access of a pull-out side drawer.
The adjustable velvet headboard sits at multiple angles for comfortable sitting up in bed, and the grey velvet finish gives it a warm, tactile quality that standard fabric or PU leather alternatives cannot match.
Key Features:
- King size (5ft), hydraulic lift storage + wheeled side drawer.
- Adjustable velvet upholstered headboard, multiple angle positions.
- Grey velvet finish, warm, tactile, and premium-looking.
- Wheeled drawer for quick everyday storage access.
- The hydraulic base reveals a full king-width storage cavity.
Pros:
- Velvet finish provides warmth and texture that plain fabric alternatives at this price cannot replicate.
- The wheeled drawer adds quick everyday access without lifting the mattress for small items.
- Adjustable headboard offers comfort flexibility unavailable on fixed-headboard alternatives.
Cons:
- Velvet upholstery requires regular brushing and prompt spill treatment to maintain appearance.
- Dual storage mechanism adds weight and assembly complexity compared to single-mechanism frames.
7. Super King Size Hydraulic Bed with Wireless Charging – Linen Grey
Best for: Couples who want the most generous sleeping space and wireless charging without cables.
This is the only super king (6ft) on this list, and the step up from 5ft king to 6ft super king makes a genuine difference for couples who want true space on both sides of the bed. The wireless charging built into the headboard surface is the other standout feature, placing any Qi-compatible device on the charging spot and it charges automatically, removing the last bedside cable entirely.
The linen fabric finish is a natural, textured material that suits Scandi, contemporary, and neutral UK bedroom interiors particularly well, offering a different aesthetic character from velvet or standard upholstered alternatives. The hydraulic base opens to the full super king-width storage cavity, providing significantly more volume than any 5ft king alternative.
Key Features:
- Super King size (6ft), 206L x 185W x 100.5H cm.
- Wireless charging built into the headboard, cable-free device charging.
- Hydraulic lift storage, full super king-width under-mattress cavity.
- Linen fabric upholstery, natural, textured premium finish.
- Grey linen finish, suits Scandi and contemporary UK bedroom styles.
Pros:
- Super king dimensions give both partners genuine space, the largest sleeping area on this list.
- Wireless charging eliminates bedside cables entirely, the only bed on this list with this feature.
- Linen fabric has a natural texture that velvet and standard upholstered alternatives cannot replicate.
Cons:
- Super king requires adequate room clearance on all sides, always measured before purchasing.
- Wireless charging is Qi-standard only, check your device compatibility before buying.
How to Choose the Best King Size Bed
- King vs super king: Standard king (5ft / 150cm) suits most UK master bedrooms. Super king (6ft / 180cm) needs at least 90cm clearance on both sides, measure your room first. Worth the upgrade if two people regularly feel cramped.
- Gas lift vs hydraulic lift: Gas lift is single-piston, simple and reliable. Hydraulic uses multiple pistons for a smoother, more balanced lift that handles heavier mattresses better. Hydraulic is the stronger long-term choice for daily use.
- Platform vs floating platform vs ottoman: Platform sits flush, stable and straightforward. The floating platform is recessed for a hovering visual effect. Ottoman lifts fully for maximum storage. Choose based on whether design or storage matters more.
- Features worth paying for: A charging station is genuinely useful if your phone lives on the bedside table every night. Wireless charging removes cables entirely, only worth it if your devices are Qi-compatible. An adjustable headboard makes a real difference if you regularly sit up in bed.
- Fabric: Velvet is warm but needs regular upkeep. Linen is breathable and low maintenance. Standard upholstered fabric is the most practical option. Match to your room’s colour scheme and how much care you want to give it.
The best king size bed is the one that fits your room, suits your sleeping habits, and gives you the features you’ll actually use every day. Every bed on this list solves a different problem, from the clean budget gas lift option to the super king with wireless charging and linen finish. There is no single right answer, only the one that works for your bedroom.
FAQs
1. Do I need a special mattress for a king size bed with a hydraulic or gas lift base?
No special mattress is required, but weight matters. Memory foam mattresses are heavier than pocket sprung alternatives and can put extra strain on gas lift pistons over time. A medium-weight hybrid or pocket sprung mattress works best with both mechanisms and is the most common pairing with storage bed frames in the UK.
2. How long does a king size bed typically take to assemble?
Most upholstered king size beds take 60 to 90 minutes to assemble with two people. A standard Phillips screwdriver handles most fixings. Beds with hydraulic mechanisms, wheeled drawers, or adjustable headboards take slightly longer due to the additional components. Always assemble on a soft surface to avoid scratching the upholstered panels during the process.
3. How do I maintain the upholstery on a velvet or linen king size bed frame?
For velvet, brush the fabric weekly with a soft upholstery brush to prevent flattening, and treat spills immediately by blotting rather than rubbing. For linen, a lint roller handles surface dust and pet hair effectively, and a damp cloth with mild detergent handles minor stains. Both materials benefit from keeping the bed away from direct sunlight, which fades fabric over time.
4. What is the difference between a platform base and a divan base on a king size bed?
A platform base uses a slatted or solid panel frame, the style used by most of the beds on this list. It is fully visible as a design piece and typically has a lower profile. A divan base is a box structure upholstered on all sides, often used with a matching divan headboard. Divans tend to be more traditional in appearance, while platform frames suit contemporary UK bedroom styles better.
