    5.0 out of 5 stars Amazing product and customer service
    Reviewed in the United States on October 17, 2017
    I was very leery about purchasing a mattress online, however after seeing a couple of reviews on Amazon I purchased a 12" zinus king size mattress. A big box shows up at the door and we did not wait to dispose of the old mattress and opening the new one at 7 am on a Friday. The mattress starts to gloriously unfold and to my surprise, the mattress isn't big enough. I panic, check my order and it says I ordered a king, check the inside of one of the boxes and nothing states the size of that thing, checked the other box and it says queen... at that point I have no bed since I throw the old mattress away, and I have a queen mattress growing on a brand new bed frame but it's not what I ordered. I contacted Amazon (which is where I purchased it from) and they are no help at all... they guy is like "well let's get you a full refund and I'll give you a discount on a new one, it will only take about two weeks to complete" what does that do for me? Nothing. And how was I supposed to return this queen mattress, when it's already unfolding? It came in a box, how do I fit it back in that box? Oh and I have no bed to sleep on! I panicked a little bit more, started sobbing and then I contacted Zinus via Facebook... Immediately received a call from a guy named Chris, he apologized for the whole thing and says "we are so sorry for this, we will send you a new king size mattress and you can keep the queen you received, we will cover the costs to make it an expedite shipping". Next thing I know after a couple of days I have a brand new king size mattress at my door. I put it on the bed, watch it magically grow and I can honestly say I can't be happier! Not only your product is amazing but your customer service was beyond great! Thank you Zinus for turning a crappy experience into something outstanding!

    1.0 out of 5 stars WARNING HEALTH HAZARD!
    Reviewed in the United States on July 24, 2018
    Buyer PLEASE Beware! I thought I was getting a great deal with this mattress turns out I got a medical nightmare instead.

    The fibers that they make the protective covering out of shed into tiny airborne fibers that you then breathe in they are similar to fiber glass. They get embedded in your skin causing itching and irritation and also when breathed in caused breathing issues.

    My husband and myself both started having horrid allergy issues and my husband ended up even having sinus surgery. Turns out our issues are from breathing in these tiny fibers! Very upsetting. PLEASE PLEASE DO NOT BUY!!!! It took us a year to finally figure out what was causing. I know have damage to my lungs from breathing in fiber glass . There should definitly be a law suit banning these as hazardous.
