I would highly recommend to not buy this mattress. It starts compressing after a while and causes back pain while sitting. Me and my roommate both are regretting having bought this mattress. On top of that customer service is horrible too, they will ask for picture proof of the compression which is practically impossible so the warranty is fake too.
negative
