What are the companion seats? The companion armchairs, which usually grow in places like hospitals, guesthouses, dormitories, schools, hotels and pensions, are also very popular in today’s modern houses. Accommodating seats are also preferred, with single or double sofa beds in 2 + 1, 1 + 1 or studio type apartments. Apart from that, luxurious houses also use a companion seat for services such as nurses and babysitters. The companion seat is said to be a seat that responds to both seat and bed needs in a sectoral sense, does not take up much space and is practical to open. Due to its advantageous use, it is preferred for institutional and individual purchases.
