You don't really. Buying a mattress can be very difficult. It ranks highest in terms of consumer dissatisfaction. (30% of consumers are unsuccessful in their first serious attempt at making a mattress purchase and delay the buying decision for up to a year. And 30% don't like the one they do finally purchase.) The problem is, because people only test a mattress briefly in the store, they don't realize the mattress is poorly designed or made with poor quality materials. European Sleep Design's mattresses not only have superior components and design, but a huge advantage over other mattresses in that you can adjust and readjust them, giving you almost unlimited options after your purchase.
