    Okkkkkkk so this mattress has been a game changer bro, if y’all looking for a good firm mattress and a decent price I recommend it for sure.

  2. Yose

    I really like this mattress altough I will say I don’t think it is extra firm like a 9 or a 10 I think it is more like an 8 like the firm o meter says but still the comfort is excellent.

  3. George

    I was quite surprised at how much I like the comfort of this mattress as I was expecting it to feel like a rock but much better than I anticipated.

  4. Brandon

    I’m a combat vet so I need firm support and I have been getting just that with this mattress.

  5. Joao

    It’s a firm mattress and it is comfortable but I don’t know if it is extra firm.

  6. Manoj

    It’s my first time using this mattress , so I have to wait to see. So far so good!

  7. Sheena

    Have to say I was hesitant before ordering this one as I was worried it might be too firm but honestly it is just perfect. Of course it is still very firm but somehow very comfortable.

  8. Hadji A

    My only worry was that since I am purchasing online without testing out the mattress, maybe the mattress wouldn’t actually be extra firm. I can now confirm that it is extra firm and at the same time quite comfortable.

  9. Barry K

    We will have to see how the mattress performs in the long run but as it stands I really like it!

  10. Elijah
