Understanding what the double quarter-turn staircase is

A double quarter-turn staircase has a U-shaped structure. This staircase provides access to a floor with a small stairwell opening. The double quarter-turn staircase consists of two parallel opposing flights of steps. They are connected by a flight of balanced treads or a landing at an intermediate level. The exit of the staircase at the landing is opposite the entry at the ground level.

Choose your double quarter-turn staircase with care

To choose your double quarter-turn interior staircase model well, select models that comply with:

• To technical constraints (size of the stairwell opening, floor height, floor space);

• To the decoration and style of the interior;

• To the use of the staircase (safety).

Take into account the available space and height

Do you know nothing about staircases? Woodup guides you so that the double quarter-turn staircase suits your home perfectly. A staircase is chosen from top to bottom — take the measurement of:

• The stairwell opening;

• The floor (finished floor to finished floor);

• The floor space.

Do not overlook the décor: the design of the staircase

Double quarter-turn staircases are just as varied as straight staircases. The majority of staircases are made of wood and pair with any type of interior decoration. Choose the contemporary double quarter-turn staircase if your interior is design-oriented. You will take pleasure in contemplating a model with a central metal stringer and solid or glued-laminated wood treads. Purchase a finishing kit to give your staircase the ideal shade.

Choosing the double quarter-turn staircase according to use

Does your staircase serve a floor with bedrooms? Choose a solid fir staircase and give it extra protection with a finishing product. Opt for a double quarter-turn staircase in beech or oak if it serves a heavily used floor. Check that the treads have a minimum width of 80 cm. Choose a wood-metal double quarter-turn staircase without risers for a loft mezzanine.

The everyday advantages of the double quarter-turn staircase

The models offered on our website are entirely designed by our experts. They embody a perfect balance between practicality and elegance. Compact, stable, safe, they offer a level of comfort praised by our customers. Discover their three main advantages.

Optimal ease of use

The shape of the staircase guarantees a comfortable ascent and descent. Its two parallel flights of steps reduce the gradient and lessen fatigue. It is the ideal staircase for regular and/or intensive use. Even with a model featuring two flights of steps where the 180° angle consists of balanced treads, the width of the treads is reassuring.

Design suited to small spaces

In a context of significant space constraints, these staircases are often the best choice. They fit into small stairwell openings while visually enlarging the room. Their U-shape, with or without an intermediate landing, makes use of corners and wasted spaces. Furthermore, they minimise floor footprint and offer storage space under the staircase.

Aesthetics suited to all styles

Woodup models come in many appearances and styles. Albula, Goules, Roques — our all-wood staircases offer a traditional and elegant design. More contemporary, the Pelletière model, with a central metal stringer and wooden treads, adds an industrial touch and contrast to your interior.

All the characteristics of the double quarter-turn staircase

The double quarter-turn staircase takes up less space than a straight staircase. It is a staircase that saves space while providing exceptional ease of use. Opt for this staircase model if you have a square stairwell opening and the spiral staircase seems too narrow for you. Discover below the characteristics of this type of staircase.

The double quarter-turn staircase: treads and risers

Each staircase model offers an option without risers. Consider this option if you need more light. For greater safety when you have young children, opt instead for the double quarter-turn staircase with risers.

Square or rectangular stairwell opening for a double quarter-turn staircase

Double quarter-turn staircases are suitable for any type of stairwell opening, square or rectangular. The minimum size for this type of staircase is often 160 x 160 cm. The U-shaped staircase generally consists of two angles (one 90° angle followed by another 90° angle, with a flight of balanced treads in between).

Double quarter-turn staircase: comfort and safety

This type of staircase allows comfort standards to be met in a small space (Blondel's law: going, tread depth and width). The presence of a rectangular U-shaped structure provides security of movement, reinforced by the presence of a handrail and balustrade.

Installation and maintenance of the double quarter-turn staircase

A staircase is a piece of furniture that is difficult to manufacture. To guarantee the safety of users, it must be made to the highest standards. Woodup has successfully combined adherence to best practices, easy assembly, model durability and minimal maintenance.

DIY installation without a tradesperson

All our staircases are designed and built to be installed by non-professionals. A private individual with a confirmed DIY level can carry out the installation. All components guarantee assembly without any modifications on your part. Our models have undergone a battery of tests before going on sale. They comply with current standards.

Assembly precautions

Before assembling the staircase, we advise you to check that all components are present. To do this, lay them flat on the floor and carry out a precise inventory. If any parts are missing, contact us before starting assembly. Also make sure that your measurements (stairwell opening dimensions and height) match the staircase dimensions.

Maintenance and upkeep

Whether used daily or occasionally, a staircase is subject to several types of wear. These are linked to foot traffic, moisture, load, impacts and exposure to light. How do you protect it? Ensure regular dusting, and avoid harsh household cleaning products. Protect the wood before first use (varnish, oil or floor finish).

FAQ - Your questions about double quarter-turn staircases

Buying a staircase online is easier than in a specialist shop. You can take all the time you need and chat with our advisors. Still hesitating? That's perfectly normal. To move your project forward, consult the answers to the most frequently asked questions.

What is the difference between a quarter-turn and a double quarter-turn?

A quarter-turn staircase changes direction only once, at 90° to the left or to the right. A double quarter-turn staircase makes two 90° turns in succession. Its advantage: it allows you to enter and exit from the same side. This specific profile saves you space.

Is staircase assembly feasible on your own?

Our staircases come in kit form. They are designed to be assembled by intermediate-level DIY enthusiasts. Although installation can be carried out solo, it is preferable to have help. An extra person makes it easier to fix the stringers to the upper floor.

Which wood species do you recommend for a modern interior?

A modern interior pairs well with a light-coloured wood species. We recommend fir or beech. Please note that fir is more suited to a secondary staircase. For a main staircase, beech is preferable. It is a species suited to intensive use.

Why is this type of staircase preferable to the spiral model?

Like the spiral model, this type of staircase fits into a square or square-rectangular stairwell opening. However, with this staircase, you can move furniture to the upper floor more easily. This is even more true for non-dismountable furniture, such as a bed base or wardrobe.

What guarantees cover my Woodup staircase?

Your staircase benefits from a statutory conformity guarantee. Its duration is governed by law — it is 2 years. In addition, it also benefits from the guarantee against hidden defects. You have two years from the discovery of the problem to invoke it.
