Trust me... the advert doesn't do the product justice.. it's AWESOME... it's delivered rolled & boxed... packaging easy to remove. The mattress was virtually fully expanded in minutes but I did leave it to settle over night.
There was NO smell at all. The product is exactly as described in size, looks & feel but is so much better than the information suggests.
I've slept on the mattress for almost a week now, deep, comfortable, supported unbroken sleep & woken feeling really well rested, no aches  pains or problems.
I'm 100% happy with my choice & would recommend the product & the retailer WayFair in this case to anyone.
Extremely happy customer
