I was hesitant to buy online, i always like to see, feel and ask questions about a product i will spend alot of money on. I took a chance and bought this mattress and platform.  Well so far i am satisfied with my purchase.  This mattress is very firm and kinda heavy. Plus the platform seems very sturdy. The only issue i had was waiting for the mattress to be shipped. It took about one week to get here. It came in a tall skinny rectangular box . Once it was open, it expanded quickly in a about an hour to it's stated size.  I am happy with my purchase. Customer service is great once u get them on the phone.wait time is way to long  to get a live person. I hope in the future they start making web sites more user friendly.
