Honestly I just replaced my mattress with financing at teppermans (along with a whole new bed) and I got the Kingsdown plush top mattress and it’s a dream!!!

Thanks for doing this! I purchased a Kingsdown mattress this past summer from Sleep Country Canada, cost me nearly $3K. I was told it’s one of the best in the store. At first the mattress was excellent. But now there’s a noticeable dent where I sleep (it’s not memory foam). It’s extremely uncomfortable and I wake up with back pain from the dent . I’m super upset and plan to speak w the store. Any idea as to why this happened or what I should do?

I have a Kingsdown that's 10 years old and still going strong. It's a spring mattress with a thick pillow top and firm support underneath. I want to say the exterior fabric is bamboo but I'm not sure. I can say it sleeps pretty cool whatever fabric it is. As a side sleeper too, it's incredibly comfortable and I actually miss it when sleeping on a hotel mattress, so I'd say it's better than hotel quality. I have no idea what their current offerings are but if I was in the market, that's the first brand I'd look at. I recall it being a little pricy 10 years ago so I can only imagine what the price tag on a similar modern one would be though.

I've been very happy with Kingsdown, which you can also get at Sleep Country among other chains. It's also Canadian, along with a bunch of other manufacturers that've been listed here

We recently moved , and went to pick out a new mattress. Together at the store, we laid on several, and selected a Kingsdown mattress. It’s been a wonderful one! I’m menopausal, and take medication that causes even more night sweats, and the mattress is still comfortable. It’s the perfect firm / soft combo as well. Of course, I always use a mattress cover to protect the mattress.

We’ve had our Endy for 5 years. It’s quite comfortable. I am 200# and have noticed a bit of a depression where I sleep, but I rarely wake with a back ache. Had a Kingsdown before, was more expensive, and broke down in just 3 years.

Kingsdown are my favorite. I'm a side sleeper so I went with the softest top, but they have medium and firm as well.
