Arrived well packaged, was suction packed and rolled as most are these days. I left it to air for 48 hours as recommended on the website, however the included instructions said 24 hours was enough? the spring indents were visable through the padding untill day 2. These are now not visable, there is no side wall padding on this mattress unlike on the mattress breakdowns pics on the site.. Its classed as medium firmness but I would say more firm, good quality workmanship. I may end up getting a foam topper in a few weeks as i'm a side sleeper and I dont feel it has enough foam depth on top to support my hips with this firmness. Overall a good value, quality mattress for the price. I'm 5ft 3, 11 stone, age 46. Bought double size mattress, comfort 800.
