Straight Fir Staircase MORENO - Cuttable Kit 285 cm, 15 Treads
The straight staircase MORENO in solid fir is delivered as a kit for on-site assembly, with a maximum floor-to-floor height of 285 cm and 15 treads (including a flush landing tread). Its cuttable design allows the height to be adapted to the actual site configuration, within the limit indicated in the instructions. The width excluding handrail is 80 cm (82 cm with handrail), for a recommended stairwell opening of 85x273 cm. Tread height: 19 cm. Going: 18.3 cm. Tread section: 200x28 mm with risers, 220x28 mm without riser.
The fir is supplied untreated: a protective finish suitable for interior use must be applied after installation. The model is available with or without risers and with or without a handrail, depending on the version ordered. The fixing screws are not supplied and must be chosen according to the substrate (concrete, timber, etc.). The floor footprint of 273 cm must be verified before ordering, taking into account finished floor coverings and ceiling finishes.

Installation advice
Checking dimensions: verify the floor-to-floor height (maximum 285 cm) and the available stairwell opening (85x273 cm recommended) before unpacking the kit. These measurements must be taken on finished floors and ceilings, including coverings.
Cutting: if the floor-to-floor height is less than 285 cm, cut the stringers from the bottom according to the cutting chart provided. Cutting modifies the height of the first tread. Always check the result before final assembly.
Assembly: assemble the stringers, treads and risers according to the instructions provided, then fix securely to the floor and the upper support. A minimum of two people is required to handle the stringers.
Anchoring: fix the stringers to the floor and the support using fixings suitable for the material (concrete, timber, etc.). Fixings are not supplied — allow for suitable wall plugs for the substrate.
Handrail: the handrail can be installed after the staircase has been fitted. It is reversible — can be fitted on the right or left when going up, depending on your configuration.
Maintenance and protection
The raw fir delivered must imperatively receive a protective finish before first use to limit wear marks and make maintenance easier. Recommended options:
- ✓ Aqua-polyurethane staircase varnish: 2 to 3 coats, maximum resistance, renewal every 5 to 7 years
- ✓ Oil-wax: natural matt finish, maintenance every 1 to 2 years
- ✓ Interior paint: personalise the colour, minimum 2 coats
Routine cleaning: slightly damp cloth, pH-neutral product. Avoid standing water on the treads. Check the tightness of fixings once a year.
WoodUp tip
Before cutting the stringers, always check the floor-to-floor height on finished floors and ceilings — including floor covering, parquet, tiles and suspended ceilings. An error of a few centimetres when taking measurements can render the staircase uncuttable once the stringers are too short.
Good to know before buying: the spindle handrail can be added after the staircase has been installed — reversible left or right. You can therefore order the staircase without a handrail and add one later if needed.
Frequently asked questions
How do I cut the MORENO staircase to my floor-to-floor height?
Cutting is carried out on the stringers from the bottom, according to the cutting chart provided in the instructions. Each centimetre removed modifies the height of the first tread. For a floor-to-floor height of 270 cm, for example, the cut is approximately 15 cm per stringer. Use a guided circular saw and work on both stringers simultaneously to ensure a perfectly level result.
What is the difference between the version with and without risers?
With risers, the staircase is closed: the vertical faces between the treads are clad, the structure looks visually fuller and lets less dust through. Without risers, the staircase is open, visually lighter and allows light to pass through. Both versions use the same stringer; only the tread section changes (200x28 mm with / 220x28 mm without).
Is the 85x273 cm stairwell opening a minimum or a recommended dimension?
This is a recommended dimension for comfortable fitting with installation tolerances. The strict minimum dimension is the staircase footprint (273 cm) + width (80 cm). In practice, allowing an extra 5 cm in width and 2 cm in length makes it easier to adjust plumb without constraint.
Which staircase should I choose for a mezzanine with a floor-to-floor height of 260 cm?
The MORENO is suitable: it can be cut to 260 cm without difficulty (a cut of approximately 25 cm on the stringers). For heights below 240 cm, the loft staircases AULAC or BASSEYRE, which are more compact, may be better suited depending on the available floor space.
Should fir be treated before or after installation?
The finish is applied after complete installation, once the staircase is fixed in place. If a handrail is planned, it can be fitted before or after finishing depending on your workflow. Treating before installation risks clogging the assembly areas and preventing adjustments. However, the hidden faces (undersides of treads, inner faces of stringers) can be treated before assembly for complete protection.
Why choose the MORENO rather than a quarter-turn staircase?
The straight staircase MORENO is suitable when the stairwell opening is rectangular and aligned along the length of the staircase, with no change of direction. It is simpler to install and more affordable. A quarter-turn staircase is necessary when the available floor space does not allow the full footprint (273 cm) to be aligned in a straight line, or when the room layout requires a change of direction.
