Renting wheelchair in Singapore is a good idea especially when:
a. You know your injuries will heal soon
b. You are in Singapore for just a short while
c. You are travelling out of Singapore and you need to rent a wheelchair there.
d. You don't want to have unused wheelchairs at the end of the day
There are many other reasons why renting a wheelchair in Singapore would be better than buying those bulky items that barely could fit your closet.
