Comfortable, strong and durable

The BOSTON staircase is available in straight flight or quarter-turn to maximise your floor space and you can choose up to 13 treads (FSC®-certified) depending on your floor-to-floor height. Choose a configuration to suit your design and interior. The handrail matches the solid-timber treads, and both the handrail and fillings can be shortened depending on the number of treads, the rise interval, and the choice of staircase format. Each tread has an adjustable rise of between 19 and 25 cm. Maximum floor-to-floor height 350 cm but can also be adapted to shorter height with a minimum of 228 cm. A straight flight staircase has a longer banister than a quarter-turn staircase as it reaches all the way from landing to the bottom tread. All components are included, together with the support pole if your application is over 13 treads. The BOSTON staircase is designed with a handrail banister and two vertical balusters fitted to each tread; this gives the stair a comfortable, safe climb. Varnished treads, powder-coated steel structural elements, a handrail made of solid wood and stainless-steel fillings all add up to a strong and durable staircase.

DIY modular staircase – Easy to install

Modular staircases from DOLLE are easy to install with no requirement for special tools. You can view our installation videos which will guide you through the installation process step by step. Need inspiration on how to make more space in your home? How about an office in the loft space? Create more space for you or the children or even a walk-up closet? Our modular staircases are the ideal solution to safely free up and access extra space. As standard we include one-side banister that can be mounted on the left or the right. You can also have the option to fit an additional banister if you intend to mount the staircase centrally rather than up against a wall. The additional banister is designed for installation on straight flight staircases.

Top tip!: When installing the staircase as quarter-turn, it is important to mount the two wall brackets we include in the package, you can purchase additional tread connectors if you wish.

Our BOSTON is a strong, stable staircase. Certified compliance with the load requirements defined in European building regulations EUROCODE to ensure we supply only high quality, safe staircases. You can also install riser bars under the treads with colours to match your staircase, this will close the gap making the staircase safer and comfortable to climb. And finally, to finish your project you can add a matching landing banister to safely secure your landing space.
