FAQ

Is there any phsical signs on the product to let the users know the need for change or renewal?

When you find obvious dent on the surface that may make walkability low, it needs to be replaced. Another physical sign may be softness on COROYAWA block portion. It also impacts walkability so may be the timing of replacement.

Do slopes and corner slopes have shock absorption?

Yes. However, the shock-absorbing capability is smaller than “mechanical block” in the center. In addition, the outside of the slopes is thinner to eliminate steps, but the shock-absorbing capacity of that part is smaller than that of the thicker part.

What is the load capacity? Are there any objects that should not be placed on top?

The heavy object with narrow contact area may cause dentes. The load capacity is 2kg/sqr cm. When placing furniture, chairs, etc., the bottom area of each leg must be at least 9 sqr cm. For example, a chair with four legs having a minimum base area of 36 sqr cm can hold up to 72kg. The weight of items to be loaded includes the weight of furniture, chairs, etc. Also, if you place a “delivery truck” or “portable x-ray machine” on the “assembled type,” it may dent or stretch the surface cover.

How long can I use it for? Does the shock absorption change over time?

The practical service life of the product for use in hospital rooms and living rooms of medical and welfare facilities is approximately 10 years, although it may vary depending on the environment and conditions of use. Even if the surface cover deteriorates over time (minor scratches, stains, or discoloration) due to long-term use, if there are no dents, cracks, or other changes in the mechanical block, the shock absorption capacity will not be affected.

How can cleaning and other maintenance be done?

Please use neutral detergent or ethanol for cleaning. When you rinse with water, be sure drying out to avoid slippery.

It is harder than I thought. Will it really prevent fractures?

COROYAWA is hard to the touch and maintains high walking stability. The shock-absorbing capacity of COROYAWA has been tested by the Nagoya University Graduate School of Engineering, and it has been proven that it can soften the impact of a fall to about half that of wood flooring. The impact of a fall on “COROYAWA” is less than the load of a femur fracture (221kgf) reported in medical literature.

Is slopes included to eliminate steps?

Yes, they are included. For the “assembled type,” ramps can be installed on all three sides except for the side that touches the bed.

Do you have data on head impact?

We have confirmed the performance against head impact using the Head Injury Criteria (HIC). We found that the risk of head injury was reduced to about 1/10 compared to flooring.

Can it be used with a portable toilet or handrails?

Yes, they can be used together. When using with a portable toilet or handrail, please make sure that your feet do not touch the slope.

Can it be used with a nursing lift?

Yes, they can be used together. The mobile lift can be used on the “Assembled Type” without any problems. When transferring, make sure that all casters of the lift are firmly positioned on the “Assembled Type” flat surface.

Is it safe for medical beds to ride up?

There is no problem even if a medical bed passes over the product. If a medical bed rides on “Koroyawa Pro20” for a long time, the mechanical block under the caster or the surface cover may be dented. *Please use a load distributing plate (sold separately) when installing under the bed.

What is the load capacity? Are there any items that should not be placed on top?

The contact area is narrow and may be dented if a heavy object is placed on it. The load capacity is 2kg/sq cm. When placing furniture, chairs, etc., the bottom area of each leg must be at least 9 sq cm. For example, a chair with four legs having a minimum base area of 36 sq cm can hold up to 72kg. The weight of items to be loaded includes the weight of furniture, chairs, etc. Also, if you place a “delivery truck” or “portable x-ray machine” on the “assembled type,” it may dent or stretch the surface cover.

Can it be used in the bathroom?

At this time, it is not recommended to use the product in the bathroom.
