My ongoing back issues solved by our new mattress! Excellent service. We tried a half and half which was good, but I found my firm side too firm in the morning. Contacted SD and a medium insert arrived in 24 hours, no questions asked. Excellent service and perfectly happy with this great mattress.

Nice quality but too firm for me, even with the “soft” insert.

I bought the mattress as well as the indescribable bed. Very pleased with my purchase. My back pain has improved as has my quality of sleep.

I still wake up in the morning wondering at how I seem to be almost floating on a perfectly flat but giving surface at my perfect morning temperature. Apparently, I used to have bouts of snoring but I don't appear to now (that or my husband is sleeping so soundly that he doesn't hear me!).

Had server hip pain and ended up sleeping with a pillow between my legs and one behind my lower back to help support me. It resulted in poor sleep and stillness to the point of chronic pain to roll over and get out of bed. After speaking with the guys at work most of them where on there second SD mattress, when I asked they said they would not buy another mattress and only upgraded to a bigger size. So I but the bullet and did it. After the first few nights I thought I had made a terrible mistake purchasing the SD, 2 weeks in….. NO Back pain, deep fantastic quality sleep, supported and no pillow between the legs or back. Would not trade this mattress for anything! Customer service was beyond amazing and I got the softer inserts sent out and I’m on could 9.

Ordering was seamless, delivery simple and the frame and matress as advertised.

Very easy process from start to finish. Works exactly how it should. Very comfortable.

I thought i couldn't sleep properly for years i put it down to menopause. I have slept better in the last 6 weeks than i have in years.

We love our sleeping duck mattress

Best purchase I've made in years
