Great mattress for all positions & for sleeping with partners
This is a fantastic mattress overall, high quality manufacturing, great customer experience, delivered quickly, and easy to setup. The cover is really nice too, adds another level of comfort and easy to wash for years to come.
On my old mattress (springs with memory foam topper) I mostly slept on my side. It sagged in the middle and barely conformed to pressure points (hips, lower back, shoulders, etc). I would often have lower back aches from trying to sleep on my back. The memory foam added enough comfort for my hips and shoulders to make due.
With this mattress I can sleep in every position comfortably (side, back, stomach). I'm especially pleased with how good it feels after a full night sleep on my back, all of my joints and pressure points are well supported and my spine and lower back feel great. Even my legs and feet feel really good while starfishing it on my back.
It feels a little firm for sleeping on my side, so at times can have a bit of soreness just below the rear shoulder plates, but it's still very comfortable and a much needed improvement from my old mattress. It would probably be a medium firm for me (I'm 5'9" & 150lbs), and medium for someone who's a bit heavier.
One of it's greatest strengths is how much it can mitigate bounce and transfer of motion. It would be an ideal choice for those who sleep with a partner as it transfers very little motion, and there is very little bounce.
It's marketed as being able to dissipate heat efficiently but I've not noticed much improvement over a memory foam topper on my old mattress, which had no such technology. I'll eventually buy new sheets so that might improve it's cooling abilities.
Another thing worth mentioning is it does have a faint foam off gassing, just like most if not all foam mattresses. It doesn't bother me at all, and as mentioned it is quite faint. I thought the smell would continue to dissipate and fade, but I found even after 30-60 days it's strength of smell has remained consistent.
With the 15 year warranty, free delivery, Canadian manufacturing, generous return policy, great price and good reviews, I was convinced that this would be a good choice for a new mattress, and it has not disappointed. I very pleased with the purchase.
