The SDIi mattress design makes it easy to keep up with cleanliness. Unzip and wash!

Purchased when moving house, after many years of poor uncomfortable sleep, often waking up to aches and pains and general tiredness. I have found the SD MachII mattress very comfortable and supportive and although my sleep habit hasn’t improved much I no longer wake up feeling like I’ve been hit by a steam train! The mattress retains its shape and comfort no matter what part of the bed I sleep on. I would certainly recommend SD.

No wake up refreshed with no problems

Second sleeping duck - can’t rate it highly enough

Cannot recommend the Sleeping Duck mattress enough. Both my partner and I are waking up better and enjoying sleeping more. Going in to the showroom to make sure the firm was the right option for us made the decision even easier so we got it right the first time.

Best mattress ever

Very comfortable and very stable for partner (rolling over does not disturb) but it is a little hot. Duck base is fantastic.

I am very happy with my Queen Half-Half (firm-medium) SD Mach II mattress. I felt the difference the very first time I lay on it. I no longer wake up with aches and pains. I sleep on the medium side, and it conforms to my bony body, but it is still very supportive.

Ordering online was easy process, delivery and construction excellent. I’m now sleeping the dream 😴

I feel that it’s not as firm as I would like.
