Perfect for a teen or guest bedroom

I purchased this for my teenage who had outgrown his twin. Shipping was fast and even better was the price. We chose the plush option for no extra cost but it still felt firm enough to provide back support and teenage rough housing. Mattress was ready in less than 24 hours with no unusual smell or issues. Would definitely recommend to friends or family.

THE GOOD, THE BAD AND THE ..?

NICE PRODUCT, DELIVERED FAST, INFLATED FASTER THAN I THOUGHT, AND HAD NO BAD SMELL AT ALL. I WAS PLEASED WITH IT ALL EXCEPT ONE THING. THERE WASN'T ONE PIECE OF PAPER RELATED TO THE BRAND, TO HOW TO HANDLE IT ... SUPPOSE IT IS MY FIRST TIME,I WOULD NOT HAVE KNOWN HOW TO OPEN IT, HOW LONG TO LEAVE IT TO DEFLATE ETC... AT LEAST A GOOD WORD ABOUT OPERATION, QUALITY, WHERE IS IT MADE OF, WHAT ABOUT THE WARRANTY ETC... IT'S THE JOB OF A GOOD MANUFACTURER...
