Q1: How can I check whether Klapster can be installed in my house?
The installation of our folding stairs depends on several factors:
Mounting surface: The mounting surface on your wall must be sufficiently long. How long exactly depends on your floor height, the gradient of the stairs and the Klapster model. The narrowest Klapster model (Ultralight) can be installed, for example, with a floor height of 265cm starting at 112cm mounting surface (run length).
Ceiling opening: When folded up, the steps and outer stringers of the staircase rest against the wall on a flat surface. Therefore, the folding stairs need sufficient space upwards. We recommend extending the ceiling opening up to the wall so that Klapster can be mounted directly on the wall. If it is not possible to extend the ceiling opening and a distance between wall and ceiling opening has to be bridged, the stairs cannot be screwed directly to the wall. For distances of up to 9cm we can offer you spacers. For larger distances, an assisting stringer made out of wood, brick or plasterboard, for example, must be installed. For assistance with installation, please consult your local carpenter.
Counter bearing / bearing surface of the outer stringer: The exiting tread of the folding staircase (movable stringboard on top) always requires a counter bearing on which the outer stringer can rest. Usually this is the ceiling, the front side of a mezzanine or the beams construction of a loft bed. The bearing surface (e.g. ceiling thickness) must be at least 10cm.
Wall structure: Klapster can be mounted on a wide variety of walls (brick, concrete walls, drywall, etc.). Primarily the weight of the stairs is transferred via the stringboard structure. Intermediate or dry walls are therefore also suitable for installation. For drywall walls, it is essential to use wooden supports and not metal profiles. It is essential that you mark the position of the supporting structure so that you can later screw the staircase to the underlying structure.
Sloping ceilings: All Klapster models require 100cm of space upwards from the last step when folding. If you have sloping roofs that begin shortly after the ceiling, check whether the Klapster can be folded up as follows: Floor height (floor to floor) minus 1x gradient of the stairs + 100cm. If you want to install handrail modules for the outer stringer for Klapster Comfort, the height of the stringer is increased by the height of the handrail (42cm). Details can be found in the data sheet "Handrail" in the download area.
Q2: How much does Klapster cost?
Klapster varies in price depending on the chosen model, your floor height, the number of steps, the surface coating and accessories. A general statement is therefore not possible. Example: For a staircase with 10 steps and surface "natural" you must calculate with the following net prices:
Klapster Ultralight: 1299€
Klapster Slim: 1799€
Klapster Comfort: 2499€
Q3: How do the Klapster variants differ?
The Comfort version offers the user easy folding in and out due to the unique spring-supported rotation axis. The step depth of 18.5 cm makes it very comfortable to walk on the stairs. Klapster "Comfort" has the highest load capacity of our models. The Slim and the Ultralight versions do not offer this support, but have lower demands on the required mounting surface due to the smaller step depth (13cm and 10cm respectively). This means that these two variants can also be used to realise particularly narrow installation situations. Further information can be found in the download area at "Data sheets".
Q4: Can I see Klapster before I buy?
Yes! Twice a month we offer the opportunity to visit us in our workshop in Frankfurt am Main. There you can see all our Klapster stairs and get an idea of our unique folding stairs. These dates are every 1st Saturday of the month from 11-15 o'clock and every 3rd Thursday from 16-19 o'clock. IMPORTANT: Please register without obligation for one of the offered dates.
Q5: Can the stairs be folded out from above?
If necessary, Klapster can also be folded out from the upper floor.
Q6: What is the difference between Klapster and other stairs?
Klapster is an auxiliary staircase for space-saving living. Thanks to its folding mechanism, Klapster fits in particularly well in those places in the living space where little space has to be cleverly and optimally used. Our folding stairs cleverly combine functionality with excellent design.
Q7: Will Klapster be mounted for me?
Klapster was designed as a modular system. The assembly as well as the later wall installation is carried out by you with assistance of a detailed construction manual and an assembly video. The installation can thus be mastered by any hobby craftsman. Of course you can also ask your local carpenter for advice and order the installation. We have no partner companies that exclusively install Klapster stairs.
Q8: How long does the assembly or installation take?
The assembly time depends on the Klapster variant. Klapster Comfort is supplied pre-assembled as a stringer-step-stringer element. With the Slim and Ultralight variants, the components are installed during assembly.
Installation including wall mounting - Klapster Comfort roughly 2 hours
Installation including wall mounting - Klapster Slim/Ultralight roughly 4 hours.
Q9: Which surfaces coatings do you offer?
We offer our stair variants in the following surface coatings: "natural", "oiled" and "white HPL".
Unfortunately, at present Klapster with black coating is not available. In the future, the Comfort model will be available again with black HPL coating.
Q10: How difficult/easy is it to fold the stairs out or in? Can my child do it?
The amount of force required depends on the Klapster variant. With children, it can be assumed that they are strong and large enough in their teens to be able to use all variants without restriction. The folding or unfolding movement corresponds more to a pushing than a lifting movement.
The effort required is highest in the Slim version, while the Ultralight and Comfort versions are about equally "easy" to fold.
Q11: Where can I order Klapster? How do I get an offer? :
You can order the stairs via our website. Each staircase must be tailored to fit your installation situation. In order to be able to provide you with an individual offer, we need the completely filled out inquiry form with your installation data: Inquiry
In order to assess your individual building project and to be able to prepare an offer, we need the requested dimensions as well as pictures, plans or sketches of the installation situation.
Q12: How do I check whether the number of steps offered matches my floor height?
The total height of the staircase (offered gradient multiplied by the number of steps) is usually one ascent lower than the floor height required and specified by you. The final ascent is achieved by the last step from the stairs to the floor of the upper area. If desired, we can also offer you special solutions in which an additional step is installed.
Q13: Do I get a discount?
We do not grant discounts. For larger purchase quantities you are welcome to contact us. Graduated prices and trade discounts are possible then.
Klapster is not comparable with a conventional store staircase. We, the team at raumvonwert, have the highest standards of quality and design for our products and services. We produce exclusively in Germany.
Q14: Can you draw the stairs in my project documents?
We assess your installation situation on the basis of the dimensions, pictures and plans you submit. Please note: We assume no responsibility for installation recommendations. For binding advice and support during installation, please contact your local carpenter or architect.
Q15: Where do you ship to?
We send the stairs within Germany and within the European Union without any problems by package delivery. Expensive shipping costs are therefore not necessary. Shipping to countries that are not part of the European Union is possible, but must be checked individually. We currently do not deliver to the USA.
Q16: What delivery time should I expect?
Our delivery times are 4-8 weeks, depending on the number of orders. Due to the great demand after our appearance on the TV show "Ding des Jahres 2020", delivery times may be longer. Your individual delivery time can be found in your order confirmation. Your order will be processed as soon as possible. You will of course be informed in case of postponed delivery dates.
Q17: Return of goods:
Check the components for damage or defects before installation. Please note that we cannot take back stairs once they have been installed if there is no technical defect.
Q18: What do I do if components are missing or the goods have been damaged?
Check the delivery for completeness with the help of the assembly instructions and your invoice. Document any damage to the package or components and contact us immediately.
Q19: Is Klapster suitable for outdoor use?
No! Unfortunately Klapster is not suitable for the weather conditions outside the apartment. However, our panels are glued according to BFU 100 and all other components are made of brass, spring steel or stainless steel.
Q20: How do I care for the stairs?
The care of your staircase depends on its individual surface coating. Detailed care instructions can be found in the assembly instructions. For additional protection of the stair treads, you can purchase self-adhesive anti-slip foils cut to size from us.
Q21: Who is Klapster?
Klapster is a brand of raumvonwert GmbH.
Q22: Has the product been tested? How long do the springs (Comfort) last?
Our stairs have been tested internally for stability. The springs and our rotation axis are designed to withstand far more movement cycles than required in the endurance test. The spring force remains almost unchanged even under intensive load.
Q23: Is there a guarantee?
The guarantee provisions of the law apply.
Q23: How does the order processing work?
After you have accepted the offer, you will receive an order confirmation with your delivery date and an invoice. Before we send the stairs to you, the invoice amount must have been transferred to our account. Payment is made by bank transfer.
