Got the hard insert, very good.

Well worth the investment

This is my second sleeping duck mattress, moved our older SD mattress into the spare room

Great mattress, excellent company to deal with.

I love the option to customize the sections of each side of the mattress to find what is most comfortable for me and my partner. It is worth the investment.

Experience with the Mach II mattress (King single) is positive. Upgraded as original mattress was quite old (over 10 years). Ordering & delivery (to home) excellent. Removal from packaging simple - loved watching it blow itself up! Comfort is soft yet firm, as it should be - clever combination

The Sleeping Duck team have been exceptionally helpful, sending out the softer mattress pads when requested, and then checking in and sending out another firmness to make it perfect! Nothing has been too much trouble. I love that the mattress has the removable cover and it is so easy to adjust the firmness. The mattress is very heavy and dense, so it is warmer than what we upgraded from, but I made sure to buy only natural fibres for our mattress protector and sheets and this has helped a lot. It is such a dream to get into bed at night. Would absolutely recommend Sleeping Duck to anyone, the adjustability is just so important, we didn’t know what we liked until we actually slept on it. Obsessed!

We have had the mattress for a couple of months now and we can't believe the comfort of it. If one of us move the other cannot feel it, fantastic. We both experience a good nights sleep like never before. This mattress is highly recommended. Also being able to change the softness was a bonus, which my wife has used to her advantage.

Since changing to sleeping duck my sleep is almost weightless, gone from waking sore to feeling refreshed

We absolutely love our Sleeping Duck mattress! I’ve noticed such a huge improvement in my sleep, but my partner loves it even more and is so grateful we decided to invest in it. It’s incredibly comfortable, supportive and has made such a difference to both of us. We couldn’t be happier with our purchase!
