How much weight can the folding stools carry?
- The Stockholm II folding stool is tested and approved for a max load of 110 kg / 242 lbs.
Tested at SP Technical Research Institute of Sweden, according to ISO 7173:1989 Furniture – Chairs and stools – Determination of strength and durability.
- The New York folding stool is tested and approved for a max load of 130 kg / 286 lbs. Tested at SP Technical Research Institute of Sweden, according to ISO 7173:1989 level 4, user weight 130 kg.
- The Chicago and Snupi folding stools are made of the same material and components as Stockholm II, and can carry 110 kg.
Can we use the folding stools outside, in the open air?
Answer: Temporary use outdoors is no problem, but pay attention to the following:
- Do not place the folding stool in sand, or on rocks /gravel. You will then risk scratching the coating around the plastic feet / slides.
- To avoid uneven load the folding stool should be placed on a firm and level surface. Extreme uneven loads might cause the “legs” to bend out of shape. As long as the folding stool is evenly loaded on a suitable base there will be no problem.
- On folding stools intended for permanent use outside, we do recommend a layer of transparent powder coating. We can offer this as an extra option.
How do we clean the folding stools?
Answer: Use only lukewarm water, a soft rag and, if necessary, a mild soap when cleaning them.
Do not use any chemical detergents or solvents!
Can the plastic feet on the folding stools / wheels on trolley make “rubber marks” on a floor?
Answer: This is very unlikely to happen. Both the plastic feet / slides and the trolley wheels are made in hardness 90 Shore and this is about as high as one can go, still offering comfort and the right feeling. A hardness of 90 Shore minimizes the risk of “bleedings”.
Are the folding stools fire proof?
Our folding stools are made of aluminum. Aluminum melts at a temperature of 660°C. Aluminum can burn but temperature needs to be extremely high (over 2000°C). In a normal fire, (after 30 minutes the room temperature is about 800°C.), the folding stools will melt.
The folding stools are powder coated. The coating powder is non -hazardous and non-flammable.
The seats are made of a high quality polyester PVC composite fabric. The seat fabric has high tear and tensile strength and elongation under load is less than 2.5%. In a fire it will burn and melt. We can however see that it is quite difficult to ignite with an open flame. It burns and melts while being exposed to the flame. When the flame is removed it stops burning. The seat material is not however classed as being non-flammable.
The extreme working temperatures are -30 to + 70 deg. C.
The plastic feet and plastic details are made of Thermoplastic Elastomer. The material is classed as non-hazardous. The decomposition temperature is about 260°C. In a fire the plastic details, like all plastics, will ignite and burn. Fumes/smoke from plastic contains carbon monoxide, carbon dioxide, nitrogen oxide and other toxic fumes. The quantity of plastic details on the folding stools is most likely no big problem compared to all the plastics that can be found in our normal living rooms.
Can the seat be changed on the Stockholm II folding stool?
Answer: We do think that this job requires a normally skilled “do-it-yourself person”, who of course first of all should carefully consider the construction of the folding stool. The person should then also carefully consider if he/she can do the job. If yes, follow the guidelines below:
Read this before starting!
We suggest that the job is done at a table.
- Place a towel, or similar, on the table to protect both the table and the folding stool from being scratched.
- With the stool in folded (stored) position, place it flat on the table.
- Firstly, note how the seat is placed – with the seams visible!
- Use a 5 millimeter Allen key (hex key) to remove the Allen screws holding the crossbar (the pipe that goes thru the seat, fixing it to the frame of the stool) that faces upwards.
- Keep one end of the crossbar in position at the hole.
- Gently move the other end of the crossbar in a direction towards the joint connector, and parallel with the frame pipe. This step might need a second person to slightly expand the gap between the frame pipes, so that the crossbar can be moved more freely. Make this step very gently so as not to scratch the coating! Never use excessive force to widen the gap between the frame pipes as this might cause the joint connectors to break! They are simply not designed to cope with excessive force in that direction.
- When the crossbar is free from the frame it should be removed out of the seat.
- Now, turn the stool around so that the other crossbar is facing upwards.
- The second crossbar is removed in the same way as the first one.
Mounting of the new seat is done in a reversed order. Keep in mind how the seat is placed – with the seams visible! Mount one crossbar at atime. Just finger tighten the Allen screws. When both crossbars are in position, tighten the screws moderately with the Allen key (hex key).
Do not try this method on a Snupi folding stool!
They are indeed very difficult when it comes to changing the seat. And also, the aluminum tubing in the New York folding stool is up one size in thickness and diameter, making it much stiffer in the frame. Because of this, the Stockholm II folding stool and Chicago folding stool are the ones most suitable for “do-it-yourself” replacement of the seat.
Are your folding stools handmade?
Answer: Without going into any technical details, our production is not automated. Each step is carried out by a skilled worker/operator using a machine or machine tools. Aluminum is known as being ”the living material”. Even though we always use material of the same technical specifications there is always a slight difference in how the material responds during the different steps in our production. To compensate for this, it is not uncommon that very small adjustments must be made during production.
Are your products made in Sweden?
Answer: Yes, they are made by us here in Sweden. Since the start in 1995, we have the exclusive rights to the complete range of folding stool products designed by A&E Design in Stockholm.
Is there a warranty?
Answer: Yes. The warranty time is 12 months and covers faulty material and productions errors. If a product is subject to a warranty claim, we are very interested in receiving a correct description of what have happened. Please include pictures as this is the best way for us to find out what is wrong.
How long time can we expect the folding stools tolast?
Answer: When treated as intended they will last for many years. There are museums that have folding stools in use that are 7-10 years old.
