This is second mattress we ordered from Hypnia, the first mattress we bought 5 years ago and it’s still used in spare bedroom and it’s still in perfect condition, the reason for second purchase of the mattress is - we bought a bigger bed and we need a bigger mattress, I made a mistake I bought mattress of other make which was returned back - back pain and only after 2 months of use change shape, I was searching to buy a suitable mattress, but totally forgot that in my house there’s a perfect company making a supper mattress, so I ordered a mattress from Hypnia again. Not much changed between mattress only the cover, it’s still the same quality. Really happy with the purchase, Hypnia mattresses are firm supportive and long lasting.
