So, you're looking for a memory foam mattress & you've seen all the advert's promising a 'free' mattress or a 'free return' after weeks or months of usage? Hypnia don't need to employ the same tactics, the competition does. Compare the price of a Hypnia and then work out why the competition can 'afford' to offer you this 'amazing offer', because you've paid upfront for 2 mattresses when you buy from the competition! Hypnia provide a quality product at unbeatable prices. Hypnia offer a 10 year guarantee & I'm writing this review after we were treated with courtesy, respect, answers and not problems. 4 years ago we invested in our 2nd quality mattress, that Hypnia stand by and will now replace due to unforeseen issues with the foam on my side of our bed, no drama, no hassles, no worries. Quality lasts, Hypnia promotes quality. Our 1st mattress was replaced after 12 years with this one, I recommend Hypnia for their commitment to after sales when needed, an important distinction these days.
