The manufacturer of this mattress currently does not have any photography available so we took it upon ourselves. We are sorry for the terrible photoshoot 🙂

    Tried a couple “extra firm” mattresses which really were not firm enough. This is exactly what i was looking for. It is actually extra firm and it’s been great for my back.

  2. Albert V

    I went in and asked for the firmest mattress they have. They showed me this one and within 30 seconds I knew it was the right choice for me. Great bed!

  3. Jeremy Smith

    The entire package was amazing but the mattress is just incredible. I thought waking up with a sore back was just who I was now but boy was I wrong. After my first night sleeping on the mattress I woke up pain free and energized! I’m a SleepMastersCanada customer for life!

  4. April B

    This is the firmest mattress I have had and I am enjoying great sleep. Not waking up with any sore points and I think it is just a great mattress for people who do a lot of sports and yoga etc.

  5. Esther L

    I know it may not be the most comfortable mattress as most people look for softer more cushioned mattresses but this is exactly what I wanted. Can’t believe I was able to find something this firm which is also two sided.

  6. Davinder

    This is a very good mattress for my back pain!

  7. Tayler A

    Great mattress with the firmness that I need for my back. Still somehow quite comfortable though!

  8. Lee

    Very very good!

  9. Cordelia

    I am very please with my mattress, it is very firm just the way I like it. I would buy another mattress from Sleep Masters Canada when the time comes, Thank you.

  10. Frank S

    Best way to describe this mattress is that it feels like a comfortable park bench :). It really is extra firm and just what I needed for my back.

  11. Sheena

    Was so difficult to find a mattress like this which is really firm and also 2 sided. As soon as I tried it in store I was sold!

  12. Jaspreet

    No kidding, this thing is really super firm!

  13. Shan S

    Just what I was looking for so thanks guys. Also, there aren’t many companies i’ve seen that made their own videos and I just thought that was a nice way of connecting with your clients. Thanks again.

  14. Kiesha

    Didn’t think it would be possible to find a mattress this firm but it really is tough as nails. Also great job on the video guys it helps to make a decision 🙂

  15. Valerie M

    Waaaayyyy too firm. Nothing wrong with the mattress or the service and I could see why someone would really like this mattress but I definitely made a mistake going this firm. Thankfully, I had it exchanged for the one level softer recommended to me .

  16. Gio

    Firmest mattress I have ever laid on if you can even call it a mattress 🙂 Not a problem for me though as I have server back issues and this has actually helped me since purchasing it.

  17. Feng

    Exactly as advertised, extra firm and perfect for me!

  18. Amir

    I could not believe how firm this mattress is! Perfect for me.

  19. Penny C

    You guys are excellent! I saw your videos on youtube as I was searching for a really hard mattress and Baris was so welcoming when I visited the store to test this mattress out. Super firm mattress and exactly what I needed, thanks again for everything!

  20. Sophie

    I lived in Asia for a year and over there I had a really firm mattress very similar to this and even though it took me some time to get used to it, after a while i started really liking it. Now I can’t sleep on anything that is not really firm and this mattress is exactly what I needed.

  21. Derek

    I know it may seem crazy to say this for a mattress that is labelled ‘EXTRA’ Firm but I have to say I was honestly not expecting it to be this firm!! There really is no difference between this mattress and putting a blanket on the floor and laying on that. I can’t believe people actually sleep on such a thing. I suppose it’s my fault for not believing just how firm this could be.
