PERTUIS Straight Staircase – Laminated Beech, 280 cm, 14 Treads
The PERTUIS straight staircase in laminated beech is supplied as a kit for a 280 cm floor-to-floor height, with 14 treads. At 82 cm wide, it is slightly wider than standard models (80 cm), providing more room to pass. It requires 276 cm of horizontal space and has a 19.5 cm tread going, slightly more than the Standard range (19 cm), giving you a somewhat deeper tread and more room for your foot.
The PERTUIS sits between the Standard range (19 cm tread going) and the Comfort range (22 cm tread going), with an intermediate tread going of 19.5 cm. The riser height is 20 cm, the treads are 30 mm thick and the recommended stairwell opening is 276 × 85 cm. The laminated beech is supplied unfinished and must be finished before use.

- ✓ Handrail can be added later: fits on either the right or left; fixings supplied
Installation advice
Check the horizontal space required (276 cm) and the stairwell opening (276 × 85 cm) before ordering. These measurements are based on finished floors and ceilings, including coverings. Drill pilot holes before screwing into the beech. Two people are recommended when positioning the stringers. The handrail can be added after assembly, on either the right or left.
Care and protection
Apply 2–3 coats of staircase floor varnish before first use. Unfinished beech absorbs dirt quickly without protection. Reapply every 5–7 years, depending on use. Clean with a damp cloth and a pH-neutral product.
WoodUp advice
The PERTUIS stands out for its 82 cm width – 2 cm wider than standard straight staircases – and its slightly greater tread going of 19.5 cm. These intermediate dimensions make it a comfortable staircase without the space requirements of a Comfort model (276 cm versus 336 cm for the GAVIA). For full technical details, including riser height, tread section, stairwell opening and packaging, see the technical specification sheet on the website or contact WoodUp customer service.
Before you buy: your choice of whether to include risers is final when you order, as the stringers are notched differently for each configuration. The handrail is optional and can be added after assembly, on either the right or left.
Frequently asked questions
What is the difference between the PERTUIS and the CHEVALARD straight staircase?
The CHEVALARD is 80 cm wide, with a tread going of 19 cm, and requires 259 cm of horizontal space. The PERTUIS is 82 cm wide, with a tread going of 19.5 cm, and requires 276 cm of horizontal space. The PERTUIS is slightly wider and more comfortable, but requires 17 cm more space.
Does the 82 cm width make a noticeable difference in everyday use?
An extra 2 cm in width may seem insignificant, but it makes it easier to pass through while carrying items such as bags or boxes, and makes the passage look wider. For people with wider hips or those who often carry bulky items, those 2 cm make a difference in everyday use.
Can the PERTUIS be trimmed to fit a height of 260 cm?
Yes, following the instructions supplied. Trim the stringers from the bottom according to the supplied sizing chart. For 260 cm, approximately 20 cm needs to be trimmed. Check the floor-to-floor height with the floor and ceiling finishes in place before proceeding.
Which handrail is compatible with the 82 cm PERTUIS?
A handrail for an 82 cm-wide straight staircase is required. Some standard handrails designed for 80 cm staircases may fit with adjustments. Consult WoodUp customer service or the accessories section to confirm which models are compatible with the 82 cm width.
What technical information is available on request?
The exact riser height, tread section, recommended stairwell opening and packaging details are available in the documents attached to the product page or on request from WoodUp customer service. These details are needed to finalise the installation layout before ordering.
Why choose the PERTUIS over a compact straight beech CHOLLIARD?
The CHOLLIARD requires just 214 cm of horizontal space but has a tread going of 16 cm: very compact, but steep. The PERTUIS requires 276 cm of horizontal space and has a tread going of 19.5 cm: it is more comfortable and wider (82 cm). Choose the PERTUIS when you have the required space (276 cm) and climbing comfort and a wider passage are priorities.
