I absolutely love my new mattress, but I worry that I will lose firmness, and I want firm..

I would wake up through the night with back pain on my old mattress . I started out with a medium firmness. When I contacted SD to organise a firmness adjustment they were very helpful and I received it with in two days. I now I have firm & extra firm and no back pain🙌🏻

With my back surgeries I've tried dozens of mattresses trying to get a good night's sleep after years of insomnia and this combo is by far the best in every way. Customer service is 10/10 aswell. They keep their word

Upgraded to a larger size SD mattress. Still great support. New SD bed frame also this time and very happy. Delivery and product instructions were also good.

a great nights sleep..

We recently purchased a new king mattress and the process was so easy. Once delivered we tried it out for a few nights and realised we had selected the wrong comfort level. It was so easy to call and get the correct comfort level inserts sent out. Thanks Sleeping Duck for the seamless experience and more so the good nights sleep

Great comfort Great service

I started out with all medium and then adjusted 1st of all to one side firm and then both sides firm. The customer service was outstanding.

I was never the mattress guy, and I never really cared about the mattress until I started to have back pains. I never thought it would be from using the wrong mattress. I took it slow at the gym, was mindful about my sitting position and I was careful at everything I did, but I would still have back aches. Then I decided to change to sleeping duck mattress and boy I was amazed. I felt so much better and I don't wake up with back pain anymore. Another thing I liked is, the delivery and unpacking is very efficient and easy. I also got an adjusted firmness which is so cool.
