Sue P –
It’s a very good mattress and the service from Sleep Masters was fabulous
Luke –
Only good things to say, I love it.
Tara B –
We are so darn happy with this mattress, we got a Queen size.
Heather –
I love my new mattress! I have to get up early for work and it is tempting to stay in bed, though I am sleeping comfortably through the night.
Kiran –
We are very content with this mattress. We have tried many firm mattresses which are just not comfortable enough and can actually cause more pain in our joints. This one is definitely firm but it does have a comfortable top which means even when I am on my sides, I don’t feel it digging into my hips or shoulders.
Brett J –
A great mattress for me. I am sleeping really well throughout the night.
Denetta S –
Very good mattress and a fair price for the quality
Andreanne B –
Super happy with this mattress
Terrance –
This is the best and most refreshing sleep I have had in a long time.
Jason –
A little pricey but now that I have slept on it I can comfortable say it is worth it.
Donny –
Not only does it look like a beautiful mattress it really is a beautifully comfortable mattress
Andy –
Such a great mattress and my lower back pain is now gone
Gilly –
Sooooo comfortable. This mattress has been a total game changer for me. Once I lay down, I don’t stay awake for very long and the best part is because it is so comfortable, I am never having to toss and turn. I often find myself waking up in the same position that I went to sleep in.
Jonathan –
It is hard to find a mattress that is actually firm but comfortable at the same time. Well they have certainly nailed that with this one.
Jorge –
I find this mattress to be a great balance between firmness but also the top layer has good pressure relief and it works for me on my back and sides too.
Isabella –
Nice firm mattress which still feels great on my sides when sometimes firmer mattresses don’t feel as good on my sides.
Charlie –
Not too tall, not too heavy and really comfortable despite being a firmer mattress. All round really happy with this mattress.
Brenda –
We have always purchased firmer mattresses as they have worked best for us so when it was time to get a new one, we knew we had to stick to firm. This mattress is probably the best firm mattress we have ever had because of the comfort it provides at the same time.
Elizabeth –
Just the right mattress for me which has helped me with my lower back issues a lot over the last month. The free delivery was also incredible considering we live quite far from their location and they communicated with us throughout the whole process.
Shawn R –
We have been using this mattress for a month now and so far our experience has been great
Murtaza –
This is for those looking for a firm mattress. It is a mattress with sides reinforced. Plus it relieved my back pain that my older soft mattress was causing. The mattress is absolutely excellent. However, I also got a bed frame and it is a great bed frame but I was told that the delivery guys do not assemble bed frames. I probably should of asked before I made my purchase but I just assumed that the customer wouldn’t have to deal with that.
Jan R. –
Mattress is firm but I was expecting a little firmer
Angela J –
Very comfortable mattress, no more achy hips in the morning.
Raya –
So this is actually my second mattress from here but the first one was not comfortable enough. I wanted something firm but also comfortable at the same time and I understand that can be difficult to find but thanks to Baris who recommended this mattress. This one really is firm but comfortable at the same time.
Mauro –
The mattress arrived about 5 days after the promised 7-10 business day window which was inconvenient but the mattress itself seems to be very good so far.
Haris –
Purchasing an extra firm mattress online without testing it can be a little daunting because you don’t know just how firm they are. I was comparing a beautyrest one and this one and eventually decided to go with this Serta mattress and to anybody reading this, if you are also wondering just how firm ‘extra’ firm is, it really is very firm. At the same time, it just works great and is still comfortable despite being extra firm.
Hobin L. –
This is such a good mattress and it really has helped alleviate the pains I had in my lower back. I highly recommend this mattress for everybody that likes a very firm comfort level.
Kieran –
I’m a back and stomach sleeper but mainly back and I have to say ever since I switched to this mattress, I definitely feel an improvement in my back pain and also my sleep overall.
Gale –
I’ve tried a bunch of extra firm mattresses and although comfort is not at the top of my priorities when it comes to extra firm, I have to say this one does also feel pretty comfortable.
Anupriya –
As far as comfort goes, it’s really good but as far as firmness goes, I don’t know if it is extra firm. It is firm but I suppose I expected extra firm to be a little harder than this.
Duran J. –
Exactly as described, a good old hard mattress good for the back
Rad –
Not much to say other than it’s a really good extra firm mattress and I recommend it.
Hussein –
These guys are great, I actually met them in the gym haha! But honestly, not just saying this because I met them in person, but they’re great guys and the mattress that they recommended for me is awesome.
Pari –
I am very thankful for your service and helping me out with the return but the mattress was not firm enough. To anybody reading this if you want a very firm mattress I would suggest looking at the dreamshadow mattress. I exchanged mine for the dreamshadow and this is exactly what I was looking for.
Doug Z. –
Baris was so patient and knowledgable when I called in with my million questions. He answered every questions I had and explained in great detail all of the differences between these mattresses and why an extra firm would work best for me. He was also kind enough to offer me a free removal of my old mattress.
Gabriel –
Overall I am very happy with the firmness of the mattress and also the price. I deducted one star because although the edges are not too bad, they’re not as firm as the mattress itself and because of that, it feels a little less firm on the edges. Other than that I love it.
Ismet –
What a beautiful mattress, very firm and good edges as well. Also, I do not feel my wife movement, very important.
Heather –
Always have and always will stick to Serta’s perfect sleeper mattresses, they are excellent, I highly recommend them.
Thomas –
I suppose I was lucky to have got it whilst it was on sale but now that I know just how good it is I still would pay full price for this.
Vacily –
The best very firm mattress ever
B. Lazow –
We were in a unique situation where we needed two separate mattresses in twin xl to fit our king bed but I need my one to be very firm and for my wife we needed a soft mattress. So we contact Sleep Masters Canada and we liked what we heard and decided to visit the store where we met Ali. Ali was very informative, not pushy at all and 100% honest. He even made specific recommendations to make sure this works out perfectly and something which we didn’t even think about ourself, like having both mattresses at the same height, etc. We are both very happy with the mattresses we took, I took this one and my wife took a Dreamstar mattress and everything worked out perfectly so our experience was just perfect.
Kazim –
Very happy with this extra firm mattress, it’s just as you would expect really firm and very good support. Might sound like I am being a little critical but I would say just two minor negatives one is that it is very tall and the other I would say that the edges are just a little softer than I would want but still not bad. Again I will make it clear that I really like the mattress a lot, just those two things could be improved in my opinion.
Xavi –
No need to think twice it is a perfect extra hard mattress
Manuel –
Extra firm is better for your back and I always had extra firm, also I never had any back pain so for me it is perfect and this is my newest extra firm mattress. It is also perfect like the others.
Serenay –
This might be the first extra firm mattress that still does not bother me even when I sleep on my side and for that reason alone I think it is the one with the best amount of pressure relief
Ivan –
Firm but not extra extra firm
Cem –
I am a heavy guy and I need extra firm mattresses but it’s also hard to find a mattress that is actually extra firm in practice, not just in the name but this one is really extra firm so it has been really good for me
Serpil –
I had a similar Serta mattress to this before so I already knew what to expect, really good!
Lexei –
Pick up the phone and call them for this mattress because let me tell you it is just perfect. If you want something really hard then you need to try this mattress.
Sherry –
Don’t think twice if you like a really hard mattress you will love this one believe me
Sepp –
Really hard and somehow still very comfortable what a great mattress
Fran –
The firmness is great and what I like most is that it’s extra firm all the way to the edges like even when you sit on the edge it’s still extra firm
Sergen Tokgoz –
I am new here and I went to Sleep Masters for my mattress because one of my close friend recommend it and I only like to sleep with extra hard mattress. I met with Ali in store and he recommend me this mattress and I just want to say it is perfect for me and I also want to say thank you to Ali for helping me.
