The king med is the best mattress we have had. I like the straightness of the matress The sheets don’t move around. We are on slats but felt it was actually better on an ensemble.base. The matress is heavy so bought a gas lift base for ease of making. I can recommend the matress. It amazes me how they fit it in a box

I've had my duck for about 5 years, I'm now updating my young adults to ther own duck.

Awesome mattress

Been pleased with my purchase over my first two months.

I have tried many different brand mattresses over the years and never been happy with any of them. I'd always seen the sleeping duck ads. I don't know why I didn't buy one sooner! Definitely glad we finally did! It's fantastic!

This is my second Sleeping Duck mattress. Won’t buy anything else now

Very comfortable, medium is a bit more soft than I was expecting but I’m used to it and it’s very comfortable now

Really like the mattress. Currently on the firm insert and happy but will try the medium. I'm glad I got it and I would get another and recommend it.

Great

I'm sleeping well - my PB has been 13 hours! I wake without a tiny niggle in lower back; and can't believe that I could make a call for free stuff! An upgrade to 'firm' mattress inserts were promptly supplied. I have seriously recommended Sleeping Duck to two couples who enquired of me.
