SUCHET Straight Staircase - Solid Fir, 280 cm, 13 Steps
The SUCHET straight staircase in solid fir is a kit staircase for a floor-to-floor height of 280 cm with 13 steps. Its width is 80 cm excluding handrail (82 cm with handrail) for a floor footprint of 229 cm — more compact than a standard 14-step staircase. The recommended stairwell opening is 229x85 cm. The step height is 20 cm for a tread depth of 16.8 cm — a shorter tread depth than the Standard range, to be taken into account for climbing comfort.
The steps have a 200x28 mm cross-section with risers. The fir is supplied unfinished — a protective finish must be applied before first use. Available with or without risers and handrail. Supplied in 2 packages.

Key points
- ? Compact footprint: 229 cm only for 280 cm of height — 44 cm less than a standard 14-step staircase
- ? Tread depth 16.8 cm: shorter than the Standard range (19 cm) — steeper staircase, to be checked according to users
- ? 13 steps: step height 20 cm compliant, reduced number of steps thanks to the compact design
- ? Handrail can be added later: reversible left or right, fixings included
- ? Raw fir: protective finish mandatory before use
- ? 2 packages: easier handling in restricted access areas
Installation advice
Check the floor-to-floor height (280 cm maximum) and the stairwell opening (229x85 cm recommended) before unpacking. These measurements apply to finished floor and ceiling. The tread depth of 16.8 cm is shorter than a standard staircase (19 cm) — verify that this size is suitable for regular users before ordering.
Assemble the stringers, steps and risers according to the instructions. Fix to the floor and upper support with fixings suited to the material. Two people are recommended for positioning the stringers. The handrail can be added after assembly.
Maintenance and protection
Apply a protective finish before first use. For fir, a 2-coat staircase varnish provides good protection (renewal every 5–7 years). An oil-wax product is suitable for moderate use. Cleaning: slightly damp cloth, pH neutral.
WoodUp Tip
The SUCHET is a compact straight staircase: its footprint of 229 cm makes it a great choice when there is not enough space for a 14-step staircase (259–273 cm). However, its tread depth of 16.8 cm is shorter than the comfortable standard (19 cm minimum recommended). Before ordering, verify that this tread depth suits your users — for young children or people with reduced mobility, a larger tread depth is preferable.
Important to know before purchasing: the reduced tread depth means the foot extends slightly beyond the front of the step when descending. This is normal on compact staircases, but it should be kept in mind — less agile users should descend facing the staircase.
Frequently asked questions
Why does the SUCHET have 13 steps instead of 14?
For a floor-to-floor height of 280 cm with 13 steps, the step height is 280/14 = 20 cm (counting the landing step). With 14 running steps, the same result is achieved but with a wider tread depth. The SUCHET reduces its footprint by keeping 13 steps and adopting a tread depth of 16.8 cm — saving 30 cm of floor footprint compared to a 14-step staircase with a 19 cm tread depth.
Is a tread depth of 16.8 cm sufficient for everyday use?
A tread depth of 16.8 cm is functional for an agile adult who uses the staircase frequently — the foot quickly adapts to the size. For children under 8, elderly people, or people with reduced mobility, a tread depth of 19 cm or more is safer. Descending is the most critical moment — going down facing the staircase (as on a ladder) is safer with a short tread depth.
Which staircase should I choose if my available space is limited to 230 cm?
The SUCHET (229 cm footprint) is the most compact straight staircase in the WoodUp range for 280 cm of height. If even 229 cm is too much, loft staircases (AULAC, BASSEYRE) or alternating-tread staircases (NUGERE) offer even smaller footprints, at the cost of a steeper pitch.
Can the SUCHET be cut to size?
Yes. If your floor-to-floor height is less than 280 cm, the stringers can be cut according to the cutting chart in the instructions. Cutting modifies the height of the first step. For a height of 260 cm, the cut is approximately 20 cm on the stringers.
What is the difference between the SUCHET and the MORENO?
The MORENO has 15 steps for 285 cm with a tread depth of 18.3 cm and a footprint of 273 cm. The SUCHET has 13 steps for 280 cm with a tread depth of 16.8 cm and a footprint of 229 cm. The SUCHET is more compact but steeper. The MORENO is more comfortable but requires more floor space.
Should fir be treated before or after installation?
The finish is applied after the complete installation of the staircase and handrail. The hidden surfaces (undersides of steps, inner faces of stringers) can be treated before assembly for complete protection. Do not delay the finish until after first use — raw fir absorbs dirt quickly.
