Have been having neck and back issues for years, although it also took a pillow upgrade, the sleeping duck mattress is fantastic.

Just a great nights sleep, as opposed to my old mattress. Upcoming hot season will determine how good it is, as I sleep very hot. (So to speak).

The SD M2 got our money because it offered adjustability. And we were glad we did. We previuosly had an Ikea mattress ( 2 different ones actually) and they were both super hard for us, despite the cost to swap to another new mattress we went with the SD for online purchase as it allowed us to add different firmness pads at no cost. This worked out well as I still found medium too firm (my partner is happy with it). I am a side sleeper and always end up on the same side which leads to a sore shoulder it is much better with the soft pad. The other great feature is that we can have different firmness levels on different sides. Great for harmony :) So despite SD not being the cheapest I would recommend them based on the adjustability for online mattress in a box purchases. Also SD sent us the softer pads as requested at no extra cost as advertised, many thanks.

Fantastic mattress, settles in quickly without sagging. No need to turn every number of week the added bonus

What more can i say but it is worth the money Thanks Boys.
