I, Mr. Samarn Kunarkornpaiboonsiri, have a degenerative knee and had a knee replacement surgery since 2009, after the operated I had the problems when using the squatting Toilet. So, I concerned about the disabled and the elderly who suffer from the same problems. Then I designed and developed the WC chair for the better quality of life of those who has that problem.
On the auspicious occasion of The Seventieth Anniversary Celebrations of His Majesty Accession to the Throne and to celebrate in Honor of Her Majesty Queen Sirikit's seventh cycle or 84th birthday anniversary, so I made the project of "WC chair, brought happiness". By clemency presented to HRH Princess Princess Maha Chakri Sirindhorn of 2,000 sets and delivers WC chairs to every province all over the country of Thailand. Bestowed through the governor of each province for 500 sets to give to the authorities responsible for overseeing the disabled and the elderly. Also donate to the neighboring countries; Myanmar, Laos and Cambodia, 2,000 sets of each country to give a royal charity to the King and Her Majesty the Queen.
