I am very disappointed with  my recent single mattress and wish to make a complaint.
There were loose threads all over the top and side of the  mattress. I pulled some and they kept going! so I spent quite a bit of time cutting each one with scissors. Now I am worried that the mattress may fall apart after a small amount of usage. It is for my grandson who stays with me once or twice a month on weekends but it has not been used yet.
Do you not have quality control?
In one of my past purchases,I washed one extra large duvet cover (grey & yellow and white color)  before usage ( with only fabric conditioner) . In 2 parts, the seams fell apart! I had to spend half a day sawing them back by hand!I have not used it since and it is folded up in the cupboard!
