AZET Space-Saving Staircase – Solid Fir, 291 cm, 13 Treads
The AZET solid fir space-saving staircase is a steep kit staircase designed for a floor-to-floor height of 291.2 cm, with 13 treads. Its 72 cm width falls between narrow space-saving staircases (65 cm) and standard ones (80 cm). It requires 229 cm of floor space and a 230x80 cm stairwell opening.
The rise is 20.8 cm and the going is 15.1 cm – typical dimensions for a steep space-saving staircase. When descending, it is best to face the steps, as you would on a ladder. The treads are 32 mm thick, and the staircase is 72 cm wide including stringers. Its orientation cannot be reversed and must be specified when ordering. Supplied in 2 packages. Handrail not included.

- ✓ 32 mm thick: treads thicker than average for a space-saving staircase, providing good rigidity under load
- ✓ 2 packages: easier to carry through restricted spaces
- ✓ 15.1 cm going: steep slope – do not descend facing away from the steps; descend facing them instead

Installation advice
Check the floor-to-floor height (291.2 cm) and stairwell opening (230x80 cm) before unpacking. The AZET is designed for a height of 291.2 cm; if yours is lower, it can be cut down as instructed. Choose the orientation before ordering – it cannot be changed.
Secure the stringers firmly to the floor and upper support using fixings suitable for each material. Pre-drill to prevent splitting. The 15.1 cm going is short: for greater safety, face the steps when descending, with your back to the open space. Two people are recommended for assembly.
Care and protection
Apply two coats of stair varnish or a hardwax oil before first use. Unprotected, unfinished fir absorbs dirt quickly. Reapply every 5–7 years. For routine cleaning, use a slightly damp cloth and a pH-neutral cleaner. Check that the fixings are tight once a year.
WoodUp advice
The AZET stands out for its 291.2 cm floor-to-floor height – greater than that of standard space-saving staircases (280–287 cm). It is an option to consider when the finished floor-to-floor height exceeds 288 cm and no other model covers that height. Its 15.1 cm going is among the shortest in the range. Before ordering, confirm that the staircase will mainly be used by agile adults accustomed to steep stairs.
Before you buy: the treads are 32 mm thick and the overall width, including stringers, is 72 cm. The orientation cannot be reversed and must be chosen before ordering. The handrail is not included and must be ordered separately.
Frequently asked questions
What is the difference between the AZET and BASSEYRE space-saving staircases?
The BASSEYRE is designed for a 287 cm floor-to-floor height, with a 14.7 cm going and a 65 cm width. The AZET is designed for 291.2 cm, with a 15.1 cm going and a 72 cm width. The AZET accommodates greater heights and offers a slightly wider staircase and going. Choose the AZET if your floor-to-floor height exceeds 288 cm.
Can the AZET be cut down to fit a height of 280 cm?
Yes. For 280 cm, approximately 11.2 cm must be cut from the stringers (291.2 − 280 = 11.2 cm). This slightly changes the height of the first step. Check the floor-to-floor height with the floor and ceiling finishes in place before making any cuts.
Is a 15.1 cm going safe for everyday use?
A 15.1 cm going is workable for an agile adult who uses the staircase regularly. When climbing, finding a foothold is instinctive. When descending, it is strongly recommended to face the staircase, with your back to the open space and your face towards the steps, as you would on a ladder. This is standard practice for steep space-saving staircases. This type of staircase is not recommended as the main access route for children under 10, older people or people with reduced mobility.
Why is the floor-to-floor height 291.2 cm rather than a round number?
The height of 291.2 cm results from the calculation: 13 treads with a rise of 20.8 cm (rounded from 291/14 = 20.78 cm). The rise is determined by the optimal calculation for the number of treads and the overall height. This sometimes produces a non-round figure, but ensures that every step has exactly the same rise.
Is the AZET suitable for access to a mezzanine?
Yes – this is a typical use for a space-saving staircase. The AZET is suitable for a mezzanine with a finished 291 cm floor-to-floor height. Check that 229 cm of floor space is available in the direction of ascent and that a 230x80 cm opening can be made in the mezzanine floor.
Can the AZET be used to carry heavy loads, such as building materials, upstairs?
The AZET is a standard space-saving staircase designed for people to use. Its 15.1 cm going and 72 cm width may make it awkward to carry building materials or heavy loads upstairs. Light items such as boxes and small tools can be carried without difficulty. For bulky materials, arrange another access route or use a hoist.
