Werner NXT 6-Step Platform Ladder
Best OverallPros
- Excellent 150kg load capacity
- Large, non-slip platform
- Folds flat for storage
Cons
- Heavier than budget rivals
- Price is at the top of the budget
The Werner NXT is the standout choice for anyone who needs a serious, stable work platform. Owner reviews consistently praise its rigidity and the feeling of safety provided by the large platform and wide stabiliser bar. It is built to a higher standard than many cheaper alternatives, with a robust aluminium frame that does not flex under load.
While it is heavier and pricier than some other models on this list, the build quality and high weight rating make it a better long-term investment for regular use. It is ideal for decorating, changing lightbulbs, or any task where you need to stand comfortably at height.
Sealey 5-Tread Platform Step
Best BudgetPros
- Very affordable price
- Good 150kg load capacity
- Lightweight and easy to move
Cons
- Smaller platform than the Werner
- Not as robust for heavy daily use
The Sealey 5-Tread Platform Step is the best value option for the budget-conscious DIYer. It offers the same 150kg load capacity as the more expensive Werner, but at a significantly lower price. Owner reviews note it is stable and perfectly adequate for painting, changing bulbs, and reaching high shelves.
The main compromise is the slightly smaller platform and a less premium feel in the locking mechanisms. However, for the price, it is hard to fault. It is light enough to carry from room to room and folds down reasonably compactly.
Stanley 5-Step Platform Ladder
Best LightweightPros
- Very lightweight at 5.5kg
- Brand reliability from Stanley
- Non-slip treads and platform
Cons
- Some users report slight flex
- Platform is on the smaller side
The Stanley 5-Step is the go-to choice if you need a lightweight ladder you can easily carry around the house. At just 5.5kg, it is noticeably lighter than the Werner and Sealey options. It still carries a 150kg rating and feels stable for most indoor tasks.
Some owner reviews mention a small amount of flex when standing on the top platform, which is a common trade-off for reduced weight. It is not as rock-solid as the heavier Werner, but for quick jobs and lighter users, it is a very capable and convenient ladder.
Draper 6-Tread Platform Ladder
Best Heavy DutyPros
- Very sturdy and robust build
- Large, comfortable platform
- Wide stabiliser bar for extra safety
Cons
- Heaviest option in this list
- More expensive than some rivals
The Draper 6-Tread is built for those who prioritise stability above all else. It is the heaviest ladder in this roundup, but that weight translates directly into a feeling of immense solidity. The wide stabiliser bar at the rear adds significant lateral stability, making it a great choice for tasks that involve leaning to the side.
Owner reviews highlight its robust feel, particularly for heavier users or those who need to work at height for extended periods. The trade-off is its weight, making it less convenient to carry up and down stairs. It is best suited for a garage, workshop, or ground-floor use.
Bosch PWB 600 Platform Ladder
Best Compact StoragePros
- Folds very compactly
- Bosch brand quality
- Good integrated tool tray
Cons
- Platform is smaller than others
- Locking mechanism can be stiff
The Bosch PWB 600 is designed with storage in mind. It folds down to a very slim profile, making it easy to slide behind a door or into a cupboard. It also features a useful integrated tool tray on the top step, which is a nice touch for keeping screws and paintbrushes handy.
While it is stable and well-made, the platform is noticeably smaller than the Werner or Draper options, which can make standing for long periods less comfortable. The locking hinges can also be a little stiff when new, but they are secure. It is an excellent choice for flat-dwellers or anyone with limited storage space.
What to check before buying a platform ladder
Before purchasing, consider the platform height you need. A 5-step ladder usually gives a 1.2m platform, suitable for reaching standard ceilings. A 6-step offers 1.4m, better for higher walls or vaulted ceilings. Always check the maximum load rating; 150kg is the standard for most domestic models.
Weight is another critical factor. Heavier ladders are more stable but harder to move. Look for a model with a wide stabiliser bar for extra safety, and ensure the platform has a non-slip surface. Check the folded dimensions to ensure it will fit in your storage space.
Mistakes to avoid
A common mistake is buying a ladder with too low a platform height, forcing you to overreach. Always buy a ladder that lets you work with your hands at a comfortable level without stretching. Another error is ignoring the weight of the ladder itself; a 9kg ladder can be a burden to carry up and down stairs.
Do not assume all 150kg rated ladders are equally stable. The design of the base and the stabiliser bar makes a big difference. Finally, avoid the cheapest no-name brands, as build quality and safety certifications can be inconsistent. Stick to reputable brands like Werner, Sealey, and Stanley.
FAQs
What is the difference between a platform ladder and a step ladder?
A platform ladder has a large, flat standing area at the top, while a step ladder has a narrow top step. Platform ladders are much more comfortable and safer for extended work.
What platform height do I need for a 2.4m ceiling?
A 5-step platform ladder with a 1.2m platform height is usually sufficient. This allows you to comfortably reach the ceiling without overstretching.
Are platform ladders safe to use on stairs?
No, standard platform ladders are designed for flat, level surfaces. Using one on stairs is dangerous. You would need a specialised stair ladder for that purpose.
Can a platform ladder be used as a regular step ladder?
Yes, but it is not recommended. The wide platform is designed for standing, not for leaning against a wall. Using it as a step ladder can be unstable.
What does the 150kg load rating mean?
It means the ladder is tested to safely support a total weight of up to 150kg, including the user and any tools or materials they are carrying.
How do I clean and maintain my platform ladder?
Wipe it down with a damp cloth to remove dirt and paint. Check the hinges and locking mechanisms regularly for debris. Store it in a dry place.
Is aluminium or fibreglass better for a platform ladder?
Aluminium is lighter and cheaper, making it ideal for domestic use. Fibreglass is heavier and non-conductive, making it essential for electrical work.
Can I leave my platform ladder set up outside?
It is not recommended. Aluminium ladders can be affected by weather over time, and leaving them outside is a safety hazard for others.
What is a stabiliser bar on a platform ladder?
It is a horizontal bar at the rear of the ladder that widens the base, providing greater lateral stability and reducing the risk of tipping over.
How do I know if my ladder is safe to use?
Before each use, inspect it for any cracks, bent rungs, or damaged locking mechanisms. Ensure all feet are intact and the ladder is on a stable, level surface.
