◆In the late 1940s, the company introduced button-free technology, quilted surfaces and extra-supportive bedding materials.
◆In 1953, Spring Air began producing its “Health Center” mattress which featured zones for different areas of the body.
◆The Pillow Top mattress was introduced by Spring Air in 1973.
◆With 4 billion dollars worth of Spring Air sleep sets sold at retail over the past 10 years, Spring Air has stayed true to quality, innovative design and value.

BI-LEVEL雙層次感應獨立筒袋裝彈簧
Spring Air加拿大廠獨家創新Bi-Level雙層次感應獨立筒袋裝彈簧結構設計，運用彈簧高低交錯的原理，較高的彈簧會先感應身體曲線並吸收身體重量，再連同較低的彈簧一起完美支撐，兩種高低層次的彈簧各自獨立運作，卻又互相協調與支援，是腰背痠痛患者最佳的獨立筒床墊選擇；其中的每一顆彈簧皆經過高規格的高溫回火藍化處理，彈性與韌性奇佳，可將獨立筒彈簧依照人體不同曲線與重量作各別支撐的特色發揮到極致，且彈簧經久耐用不疲乏與變形。
