The mattress ordered never inflated to the full inches I paid for; ordered a 12 inch mattress & paid for the extra 2 inches, however, after leaving the mattress in the sun for 3 days, it has remained at 10 inches (I’ve measured on each side). Keep in mind I have NOT used the mattress, laid on it, or added sheets or anything, I’ve done some “fluffing” to encourage the inflation but to no avail ): really bummed. 

Having already throw out the packaging, I’m not sure if I was sent a 10 inch by accident or if the mattress is just defective. I ordered online for convenience of not having to drag a mattress up but was skeptical that this exact issue would occur & it did. Now I’m stuck with a mattress I don’t want unless I get help from customer service on a refund for the difference in inch or a thick 2 inch mattress cover to account for the what I’m missing.
