Arrived 4 days after delivery date. But fortunately, UPS is trustworthy in Phoenix AZ during holiday weekend. Really awesome gel & memory foam mattress. Very firm but soft support for whole body. Actually firm enough support that you will not sink into mattress. Feels like my body is floating on a cloud. Perfect for lower back pain & leg joint aches. I have sciatica & ruptured acl in one knee. No more tossing & turning. This mattress feels like heaven. Mattress arrived wrapped in protective plastic & then vacuum sealed in very thick second plastic outer shell & inside very compact box. Got it up 2 flights of stairs easily. No odor whatsoever when opened... Mattress decompressed to full 11 inches instantly! Perfect!!! Other than delayed delivery, almost perfect 1st time wayfair customer experience. Thanks.
