    It’s strange because the part where you sleep on is quite firm and also comfortable, but the edges which I like to use to sit on before i get up is really soft, I don’t understand why they have done that

    King size extra firm mattress for just over 900 bucks delivered i could not ask for better than that

  3. Aleyna –

    Sleep masters took our order on short notice and delivered it to us the next day and they didn’t charge us any extra delivery charge for this express delivery so I am very thankful. Also, the mattress is perfect for us and exactly what we were looking for.

    I trusted you guys enough to not even try the mattress before I ordered it and i’m glad I did because it has worked out perfectly.

  5. Steve –

    Overall it’s a mattress that I like, the positives are way more than the negatives. I would say probably the only negative for me is that maybe it could have been a little firmer? For most people it may be firm enough, but for a mattress that is supposed to be extra firm I wouldn’t mind it being firmer.

    Purchased it online thinking how badly can you make an extra firm mattress, but this one was really bad. Firstly, it’s not even extra firm, secondly it’s way too heavy for me, i’m a senior how can I rotate this on my own?

    Purchased 2 SXL mattresses and it was delivered approxiamately 1 week later. We are really impressed with our mattresses.

  8. Kev –

    Exactly 5 days after I ordered it was delivered to me at a time slot that I asked for so thank you for your service and the bed is exactly how I want it

  9. Ether –

    This mattress is not firm enough to be an extra firm, maybe just a regular firm but not extra firm

  10. Lucas –

    It wasn’t too bad but I have to say the orthopedic supreme mattress is much better and thank you sleep masters for allowing me to exchange so smoothly without any issues

  11. Berkan –

    For me the mattress is amazing but I always liked very hard mattresses anyway

  12. Grant –

    This was not a good extra firm mattress and I do not recommend it, but we exchanged our mattress for the Dreamstar Orthopedic Supreme which is also here at Sleep Masters and that one is amazing, I recommend that one over this for sure.

  13. Ngolo –

    Good price for an extra firm mattress

  14. Muro –

    Very firm and cool at the top with strong edges which is all I wanted from my new mattress so this checks all the boxes.

  15. Joey –

    Sleep Masters is the best mattress store and you must go speak with Ali and you will understand what I am saying

  16. Alexis Juli –

    All the best to you guys thank you for my amazing new mattress and I will recommend more people to you
