This is a a fantastic item! I need to store my king size down mattress topper (which is twice as thick as a duvet) and struggled to find a big enough bag for it. This did the job perfectly - the inner vacuum bag is massive and the outer case keeps it looking neat and fits easily under the bed. The topper was reduced in size by about 80% I would say, making it far more manageable to store. Highly recommended.
