  1. Georgia P.

    I have arthritis and I need something not too soft or too firm to relieve my pressure. This mattress does exactly that and I am really satisfied with it.

  2. Patrick

    The balance they have with this mattress is just so perfect!

  3. Elizabeth

    We initally went with the extra firm model of this mattress and it was too firm for us. We then exchanged it to this medium and it works so perfectly for us. Thank you to Sleep Masters Canada for making it so easy for us to exchange!

  4. Veronica

    I didn’t realize how important a good mattress was for me until I purchased this mattress and started sleeping on it. I’m waking up super relaxed and completely pain free every morning!

    My mattress was delivered at the day and time that it was promised. Really comfortable too I am in love.

  9. Teena

    Hands down the best mattress I have ever owned. If you like a mattress to feel both firm and soft you cannot go wrong with this mattress, trust me!

    Not too hard and not too soft. Perfect balance and very comfortable.

    This is a great product and very comfortable

  13. Allen S

    The comfort, the quality, the height of the mattress is all perfect. Great mattress.

  14. Annie D

    Très confortable

  15. Brynn

    We noticed a big difference in sleep quality in upgrading to this mattress. My partner and I have very different sleep styles and mattress preferences but this one gives him the support he needs (stomach sleeper) while still giving me the softness I want (side sleeper). Would recommend.

  16. Ray

    The best compliment I can give this mattress is that I would buy it again and again.

  17. Brian G

    My wife loves this new mattress. It is firm but soft at the same time which seems to work well for both of us. Overall, really happy with the service also.

  18. Elizabeth G

    I was in search for a new mattress since my old one was giving me back pains. I was helped out by the online chat person who recommended me this mattress after I had given her the breakdown of my situation. I’ve had it for 2 weeks now and my back pains have been getting better every day!

  19. Anne

    I am thrilled with mt mattress. It is neither too firm or too soft and works great for me.

  20. Rena L

    No Joke i’ve had a lot of terrible mattresses in the past but this one is just perfect. It is just what I needed.

  21. Richard

    My wife and I moved to a new home and we wanted to also get a new mattress as a gift to ourselves. We took a bit of a risk as we didn’t really have the time to go and try these at the store but we got some info on a few different models and we were then recommended this model. We decided to go with it and it might just be my favorite thing in the new house lol.

  22. Chinton F

    A great quality and highly comfortable mattress.

  23. Randeep

    This is the closest feel we have had to the mattress we tried at the Hilton hotel in New York and it is fabulous

  24. Hillary

    This mattress checks all the boxes so overall a great product.

  25. Joann F

    Much better quality than I was expecting and I realized that this literally is the same mattress I was seeing at Sleep country which had a different name and they were selling it for like double the price. Crazy.

  26. Christie L

    I have to say that it did take me a while to get used to this mattress and I was hesitant at the beginning but now I am really happy and really satisfied with it. I think this was because I had my previous mattress for 25 years and my body was so used to that one.

  27. Maria

    Not too firm, not too soft. Just perfect.

  28. Arani

    Very comfortable mattress and great delivery service

  29. Hunter

    The mattress is amazing, I upgraded from an older simmons beautyrest mattress and this one feels a lot better.

  30. Jodi

    First I purchased this mattress for myself and I loved it! Then I purchased one for my parents and they are having much better sleep because of it!

  31. Tina

    I’m really happy with my mattress and I have to say it has been great for my lower back pains too

  32. Diogo

    No wonder this mattress was reviewed so well, it has the perfect balance between softness and firmness. The only downside I can think of is the weight, it is a little on the heavier side but the comfort is amazing.

  33. Paolo

    a very good mattress which feels both soft and firm at the same time. No off gassing which is an issue we had with our old mattress and the delivery guys were excellent.

  34. Leo D

    It’s a really good mattress it must be said but I want to comment on the service that we received because it was astounding. The guys were in and out within minutes, kindly took their shoes off, put the new mattress on our bed frame upstairs and even took away the old one. All we did was literally open the front door.

  35. Bruno

    Very comfortable, very supportive and an all round great mattress and experience from Sleep Masters.

  36. Lila

    My husband and I have decided this is the best mattress we have ever purchased and that says a lot since we have always had really good mattresses.

  37. Scarlett

    Oh God I did not know about how many options there were when we first started looking for a new mattress. A week into our search we were even more confused than when we first started. I don’t know if all these new mattresses are great or if we are just lucky to have found this model but we really like our new mattress. It is a little heavy but I guess that’s how they are nowadays!

  38. Lizzy G

    Beautiful mattress and so worth the price. I’ve slept on a similar mattress at my grandparents house for a few years and when I was ready to purchase my first mattress my grandmother referred me to Sleep Masters. Great service and great products. Thanks Sleep Masters Canada.

  39. Lorena

    What a great company, we tried the mattress in store, they helped us out with the pricing and delivery and the whole transaction was super easy. The mattress is just what we were looking for as my husband is more of a back sleeper and I am a side sleeper so we were told we needed something that is not too firm or not too soft. This mattress works perfectly for the both of us.

  40. Masha

    LOVE my new mattress and very happy about the sustainability side of it.

  41. Wade

    Just received my mattress but it seems like I love it. Will need to try it out a few more nights but all round the service was excellent.

  42. La

    The mattress is good but I should have read the specs better as it is huge and too big for my bed frame. I don’t know why they make the mattresses so big nowadays. Would always have like a 10″ mattress and it was great. Now you can barely find a mattress less than 12″.

  43. Margaret

    I don’t understand how they called this mattress a medium it is way too soft to be a medium

  44. Christian

    This is the best sleep I have had in years. I have waited way too long to buy a mattress like this.
