the fellows had a rough time  bringing the mattress upstairs.. but they prevailed and set mattress on bed.. the mattress has been a God send.. extra firm like we wanted and so very sturdy and comfortable for my husband and myself .This mattress is very thick and gave us the support and comfort we been needing in years cause we both have very bad backs..oh my gosh...it has helped us tremdously and we have never slept better.. It's a great mattress and theres no regrets in making our purchase.. we also bought the conshohocken low profile bed.. the bed is beautiful and didn't take no time to put  together well worth the purchase for the price.. and guanteed you will get the best nights sleep you ever had.. if you like extra firm... good support on the sides of mattress as well..  a great puchase and would recomend to friends
