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

The only way you're going to get away from some motion transfer is by getting a decent coil system. The purple is absolutely one of the worst mattresses for motion transfer out there. Tempurpedic is really good at avoiding but you'll need to go up to the pro adapt soft line for your desired feel. You could also look at some of the Kingsdown mattress', Matt warehouse has a couple that could serve you well. Sunham or Wilcrest.

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.
