    This is a very comfortable high quality mattress. So far so good for me!

  2. Krista

    This mattress is nice and firm but not too firm. I find it very comfortable and I love how it makes no movement when my partner is moving around.

  3. Linda M

    Sleeping like a baby. This mattress has a firmness to it but a comfortable top at the same time. My favorite thing about it is that it is always cool.

  4. Kathleen F

    We purchased the Queen size and honestly I’ve never looked forward to going to sleep as much as I do now. It’s always cool, firm but not too firm and no motion transfer at all

  5. Shelby

    I replaced my spring mattress with this firm iComfort and it is one of the best choices i have made in a long time. Completely changed my sleep for the better.

  6. Victoria

    This is my first purchase from this company and I am very happy with the mattress and also the service. I have recommended them to my family and friends.

  7. Paul S

    Tried it in the store and loved it right away. Ordered it and the mattress came on the day they said it would. The delivery guys even took it up and placed it on my bed frame for me. Really happy with the quality of the mattress and also the service.

  8. Dragana

    Really good mattress. We had slept on it at a Hotel for a couple of nights and we fell in love with it and decided to buy one for ourselves.

  9. Natasha

    We’ve had this mattress for a while now and its soooo good!

  10. Angela D

    This is a definite 5 star. The mattress just has a perfect balance of firmness and comfort. Like you feel the firmness come from beneath but the top part of the mattress is still very comfortable and soothing.

  11. Emre

    I am super happy with this mattress, it works really well with my adjustable base and the comfort is just what I was looking for. I wanted a mattress to be firm but not crazy firm. Also, the fact that the surface is always nice and cool is such a bonus!

  12. Natasha

    This is the best mattress I have had without a doubt. I like firmer mattresses but not like a rock it still needs some give at the top and this mattress does that perfectly.

  13. Nancy Doherty

    Thankful to Sleep Masters for making this really easy for me. I did not have a clue of what type of mattress to get but I was informed of all the types in the store and then recommended this one for all my needs. Delivery was also really easy!

  14. Tomson

    Our experience with Sleep Masters Canada was outstanding and it is honestly good to see that there are still honest businesses out there. From the knowledagable sales staff to the excellent delivery team, everything was incredible. I will make sure to recommend all of my friends to you guys. Thank you for everything.

  15. Chantal

    No more sore back for me or sore hip for my husband. It’s the perfect mix of support and firmness for a great nights sleep.
    We definitely recommend.

  16. Vesime

    Not good mattress, I didn’t like

  17. Mahdi

    We replaced our mattress with this iComfort firm and we are very happy with it.

  18. Don R

    Very comfortable mattress I was just expecting it to be a tiny bit firmer.

  19. Haysam

    I’ve had terrible lower back pain for a very long time which is probably also due to my work as I do construction. I’ve purchased this mattress and I have now been sleeping on it for just under a month. For reference, I am 205 lbs and I like to sleep on my back and my sides and this mattress has definitely helped with my pains. They are not completely gone, but I would take this over what I had before any day of the week.
