It is a huge risk buying a mattress on-line without the option of trying it out first, but we took the plunge and it turned out to be a great decision. The mattress arrived within 3 days of ordering it and it was easy to unpack and it 'inflated' very quickly. There was little or no odor and we slept on it the same night. It feels a little soft when you sit on it but once you lie down it feels firm without being hard, supportive without being rigid, and it conforms to your body and feels comfortable immediately. We do prefer a firm mattress so this did not disappoint. There is barely any movement when your partner gets up or changes position and definitely no aches or pains in the morning. I could not be more pleased with the quality of the mattress, the ordering and delivery process and of course, the timing of the free shipping offer - you cannot beat that! Overall I would highly recommend this mattress and we are delighted with our purchase!
