Will not answer telephone
I purchased a mattress from Amazon through a person called Bednation. The manufacturer is Joseph International. The mattress is extremely dangerous with a spike digging up through the top of the mattress. I awoke one morning to find I was being stabbed in the side. This mattress was purchased 2 years ago, Bednation have disappeared so I tried to contact the manufacturer. Every time I tried to call them the call was terminated at their end and 23 attempts later I gave up. Next day tried again but still not contact.
Beware of purchasing a mattress made by Joseph International because you could have a very nasty accident if you slide down the bed and tear your skin wide open on the metal within the mattress. I do have images of this spike protruding but unable to attach them here.
I would not like the thought of you buying a mattress for your child and them being very seriously injured.
