My very serious back problem has led me on a hunt for a mattress that has equal amounts of give and support so that my spine stays absolutely straight while I sleep. This search has led me to Hästens, the absolute most high end of beds, in fact, the King of Sweden sleeps on one of these. The prices range from a steep $6,500 to a whopping $67,500. It sounds ridiculous but these beds are so amazingly comfortable that I am about to sell all my worldly processions to buy one. The prices vary depending on thickness of mattress, thus amount of material used. Everything is 100% organic (genuine horsehair for absorption of heat and moisture and allows proper ventilation), and it’s all handmade and comes with a lifetime guarantee. It is hard to justify the price tag without first hand account – it is like sleeping on a cloud! They make a crib mattress that has all the benefits but is only $700. They offer this without a markup because they understand the importance of proper sleep for babies and kids (and well, to get them hooked while their young!). The children’s mattress cover is machine washable. I would seriously consider this if you are in the market for a crib mattress because you are getting something really extraordinary for a high but still accessible price. Go to their website for store information.
