I did not know Serta had a hybrid series in their offering, and after 15 years of sleeping on a Simmons Beautyrest firm mattress, I discovered true sleeping joy in the Serta iSeries 500 Cushion Firm mattress. It was my perfect compromise between firm (needing more support) and plush (desiring cushioning and comfort). I cannot believe I put my body through the injustice of sleeping on a mattress that no longer provided support, and certainly as a firm, had little comfort/cushioning compared to what I have now with my new iseries 500 Cushion Firm! The hybrid is exactly what I was looking for but could not articulate! I love the mattress construction, feel, height and depth. Thank you so much for coming up with sleeping solutions to meet complex physical needs, and for doing your homework to bring an excellent product out to the market! Wow I am impressed. Everyone is trending with the foam mattresses and I am sure they are great for some, but for those who need solid reliable back support to maintain correct alignment, while also relieving pressure points and providing a cool sleeping solution that is soft to the touch--I give your new Hybrid lines A ! Well done! I did go and try out the Simmons Hybrid line, and I went with Serta because the comfort was just what I wanted and needed. I can sleep well now, I have no pains, no aches, and finally--FINALLY I can sleep well again! I am so happy I went with this purchase. I know its a mattress, but when you have a real need and it is met in every area that counts, nothing can replace the pleasure, enjoyment and joy of experiencing true restful sleep night after night. Thank You Serta! You have restored my comfort in resting, you have a new customer for life!

Now Wanting to Go to Bed At Night

September 26, 2017


My wife and I have tried several different mattresses and toppers over the last 10 years. We both have sore necks and shoulders constantly for our efforts. After sleeping on our daughters older iSeries bed for a week, we finally ponied up and looked for a new mattress. Of course they don't make that mattress any more so we found one that the build was very comparable. We are both extremely pleased with this bed, iSeries 500 Cushion Firm. It is very comfortable and supportive at the same time. It's great to start healing and sleeping good once again.

Best Mattress Ever!

January 21, 2018


My wife took me to look at mattress one day because the old king we owned was unconfortable and the springs were not even. I like a firm mattress and she likes one to be soft, so we thought we would have a hard time mutually choosing mattress, but both of us ended up choosing a Serta I Series 500 Cushion Firm. It was the first mattress that when I layed down on that I actually laid there and relaxed. We both laid there and just knew it was the perfect mattress for us. Our first night with the mattress, best sleep we have both have in a long time! Everyday we both wake up and lay in bed a little longer than we ever did in our last mattress. We brag about this awesome mattress to friends and family, it has become one of our favorite possesions. I do not regret at all going to look at mattresses with my wife that day. I was slighly bored and didnt want to mattress shop, but little did I know my life and sleep would be changed dramaticlaly for the best! We love our Serta!

Great Mattress

January 22, 2018


This is the best mattress I have slept on. It is nice and firm underneath the soft cushion surface. I have always owned a Serta mattress and have always been happy with the quality and performance, however; this is by far the best one I have owned. I would highly recommend it if you need firm support underneath and want a soft surface.

Perfect mix between very firm and too soft

February 24, 2018


I went into Mattress Firm last week in need of a new set after having my pillow top queen for 10 years - way too long and my back has been killing me. I knew I didn't want a super soft mattress like the last one, and the "Firm" ones were way too hard. The ISeries 500 won me over for its perfect balance between too firm and too soft. It has a nice plus texture, but a thin one so it's not puffy like a pillowtop. And it is extremely supportive but also somewhat soft at the same time. I like that it does not have a lot of give, as with back problems the last thing you want to do is have the mattress dip in. Overall, I am very pleased with my purchase!

Horrible buy

April 22, 2018


After a year the box spring gave out. We discovered that it wasn't even a traditional box spring, but a pathetic attempt at making a box spring for half the cost by not completely enclosing it. There was only one side that had wood and the rest was very soft wire the bent under the slightest pressure. The mattress we've had for three years now, and it is complete trash. Springs are damaged and create hard spots and raised areas that make the mattress so lumpy and uncomfortable that it is not for to sleep on. This was with the normal use of a healthy- weight couple. We have a ten year warrany and we'll see what they say about it.

nice mattress for support and comfort

We have only had it a short while. It is IComfort Blue touch 500 plush and my back loves it. Very supportive yet so soft. I can't feel when my wife gets in or out or moves around.

I have owned this mattress for about 3 months now and have not had one good nights sleep. Unfortunately i used the return policy from a 100series mattress to the 500series and i feel just as uncomfortable on this mattress as the other firmer one. My upper and lower back are always in pain every morning and i have tried so many different sleeping positions. Stomach, side, and back br can never get comfortable. Sadly i paid for an expensive luxury mattress but have slept better on many other mattress and now i am stuck with it. I feel as if once you warm up the foam you hit rock bottom with those stiff coils they use and i end up not being alligned properly and sleeping on a stiff surface. Was told to let the bed break in for 60 days roughly but after 3 months i feel no difference and just restless nights.

Great Matress

July 16, 2018


I did a lot of research before purchasing this Matress. I have a bad hip and would wake up throughout the night on my other Matress. At first, I thought I was going to have the same problem with this Matress as it seemed firmer than I expected when it was delivered. However, after sleeping on it for a few weeks, it softened up a little and I have adjusted to the support and can now sleep through the night. I also like the fact that it is a hybrid with both foam and wrapped coiled springs. All in all, this was a great purchase.

Good Night!

I purchased this bed set to replace a 17 (yikes!) year old mattress and box spring. The new bed was very comfortable even the first night. No break in period needed. I tend to sleep very warm but this mattress keeps me cool and comfortable.

Your back will thank you!

September 16, 2018


I have not had this mattress long, but I can already say with certainty that after one night on it, I made a good choice. This is a very firm mattress, but it seems to support my spine in the most comfortable way possible. I am mostly a side/stomach sleeper. I tend to wake up with horrible stiffness and pain in my lower back, and I am an active, healthy 28 year old. I blame my bed. My old mattress was a purely memory foam bed, no springs or inner support, and had developed a huge dip in the middle of the mattress after only 5 years of sleeping on it every night. I have high hopes that this mattress will hold up decently for at least the next 7 years. I purchased this particular mattress from Big Lots, and took advantage of a sale promotion, plus a coupon. I got a great deal. Fingers crossed on quality, but so far I am extremely happy and resting better already. This is heavy, seemingly well-constructed mattress. Thank you Serta!

Serta I Series

September 30, 2018


Purchased this King size mattress from Sears Canada in April of 2016, Tried to return this mattress after just 3 months and was advised because they were going out of business the could no longer honour the warranty. This mattress has been an absolute nightmare. It is so bad that I have now taken to sleeping on the living room sofa. I am now in the process of trying to contact Serta via their help/contact us am am having no luck. Compared to the last king size mattress which was like sleeping on a cloud, it lasted for 18 years. This mattress which set me back close to $2000.00 CDN.means that in just 2.5 years I will have to spend at least another 2 to 3 thousand dollars to get back to sleeping in a real bed.

I was not sure what kind of mattress to purchase but Allan my sales person was so patient and knowledgeable. He asked about my sleep habits and preferences and directed me to a few really good options but I fell in love with the I series. We received it yesterday and i had the best night sleep I've had in years! This mattress is wroth every penny!

This mattress is very well made of high quality material compared to similar mattresses that cost more.

Went from a regular coil spring mattress about 7 years ago to (at the time) a newer memory foam mattress. Transitioning to the memory foam took some time but I was happy with the firm yet body cradling support. This hybrid is really the best of both worlds in my opinion. It provides excellent firmness and support with a pillowy soft top layer that has helped relieve the lower back and hip pressure I was experiencing.

Best sleep of my life!

I love this mattress! We’ve had multiple big name mattresses before, but this is our first Serta. The mattress is very well made, easy to handle/move. It’s comfortable, firm but plenty of cushion. When one person moves it does not make much movement on the other side. We LOVE this mattress!
