VERY COOL SHIPPING . DELIVERED TO MY DOOR VERY HEAVY BY THE WAY . ONCE UNROLLED THE MATRESS RISES TO TAKE PLACE . I WILL GIVE IT A WEEK BEFORE MAKING MY FINAL DECISION AS OF NOW IT DOESN'T SEEM TO ME FIRM AT ALL . IT SAYS IT REQUIRES 24-48 HOURS I HOPE ITS WORTH SLEEPING ON THE FLOOR UNTIL IT FULLY EXPANDS . If it doesn't work out I hope I can get my money back so I can go purchase a mattress at a furniture store I think I learned my lesson of ordering a mattress in the mail
