These odd-looking blue protuberances, installed at the Provenza station in Barcelona, were initially mistaken by passersby as some form of bicycle parking.
In fact, they're ergonomic pieces of street furniture:
"25º is the name of a lumbo-dorsal support element that allows the back to rest and generates a balanced, comfortable and healthy posture. Supporting the back relaxes the muscles that we have on both sides of the spine and causes the stretching of the spine, allowing more flexibility to our trunk and improving its ability to twist."
"They are anthroposomatic supports that cause a more comfortable posture. Due to its structure, which causes the user to relax the muscles on both sides of the spine when supporting the back, the support relieves tension in the vertebral musculature to induce a balanced posture."
"The shape of this support, starting from 25º from the upper part, adapts to the body through a variable inclination, the result of tests carried out on people of different sizes and builds. Produced in 2mm-thick machined and welded sheet metal."
These were designed by architect and ergonomist Antonio Bustamante and industrial designer Marc Llagostera.
