Our friends told us about their Sleeping Duck. We bought one 2 days later. I started with Medium for my wife and Firm for me. I quickly realised that I was a side sleeper and needed a Medium as well. SDHQ sent a firmness adjustment though the post. No questions asked. I now sleep much better.

The Sleeping Duck Mack 2 is amazing and so comfy when I sleep on my side but still have some discomfort when I lay on my back. Overall a great mattress and easy to interchange the firmness adjustment.

FANTASTIC !!!!!

The medium mattress I bought from Sleeping Duck was slightly too hard for me, so they sent me the 'Soft' inserts and it is just right now. No extra cost! Great service.

No interruption to sleep through partner movement. Full support of body. Major change in sleep patterns ! We love our new Sleeping Duck.

Not overly happy,have 2 other sleeping duck mattresses at another property with I'm very happy with, but this one seems non supportive. It's on a slat base so shouldn't be that.maybe the other two are firm and the current one is.medium.not sure.but definitely not as happy as I've been with the previous two

Wonderful sleep on our KS Sleeping Duck mattress. Thank you

Look forward to going to bed now

Very comfortable

We bought our Sleeping Duck about 5 months ago. It was great from the first night. We’ve noticed over the last 5 months is softened a little bit and now it’s perfect. It can be quite hard (even the medium) for a little while. Getting perfect sleeps on it every night.
