The mattress was ordered for a new four poster platform queen sized bed the I got from Wayfair earlier in the month.  The bedroom is being furnished for my grand daughter who visits regularly.  The mattress arrived within two weeks and the delivery men were helpful in getting up to my second floor landing.  From there I had help from my son to lift the mattress and place it on the bed.  The quality of the mattress and the covering fabric is excellent.  My grand daughter slept in the bed for two nights and said it was the best sleep she's had in a very long time.
