Swedish company Hästens has developed a hand-made horsehair mattress, costing $56,000, which has been highly praised for its comfort and support.The horse mane and tail strands are heat-treated, braided, and steamed to create permanent curls that give the beds an airy and supportive structure.The Hästens 2000T model, which was tested, includes 2,300 coil springs and comes with ongoing care, including a calibration program.Although the mattress comes with a premium price tag, it is seen as a potential worthwhile lifetime investment for those who can afford it.
