Delivery excellent 3 days early from Wayfair and at 7am as advised, opened mattress that day at 6pm, bit of a struggle to get it upstairs being pensioners as it is quite heavey,  now waiting for it to fully expand, in the spare bedroom, looking good already after 12hrs but will give it another 3 days, not in any hurry as I'm waiting for the Emma mattress protector to come from elsewhere, Mattress on Line as it's cheaper on, but it's still rather expensive for what it is though, Emma's own price is way over the top in my opinion, will come back with a further review once we have tried mattress for a while and if it's as good as they say it is from other reviews we will be quite happy, time will tell?
