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!

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!

Getting better night sleep now

September 29, 2018


I previously owned a Simmons Beautyrest pillow top mattress that I had for some time now.it was time to shop for a new mattress. went to my local Mattress Firm tried out several mattresses. the sales representative was very knowledgeable. I compared this iSeries 500 CFM mattress to a $3,500 mattress it was just as comfortable for a lot less. had it delivered started sleeping a lot more comfortable the first night and still am. no more achy joints or sore backs this mattress takes care of all the pressure points. very happy with it. I highly recommend this mattress.

Very cozy, molds to my body

August 29, 2018


I like the firmness of the mattress, yet it feels soft against my body. When I lie into a position, it cushions around me. When my husband is changing to a different sleeping position, I barely notice it. It is very good to have a mattress protector on this bed, as well! I'm so glad we took the advice of that. Also, I rotate the mattress monthly. As I look at the mattress, it looks the same as the day it arrived (9 months ago). I feel like that with the care we put into maintaining the quality of the mattress (clearly directed by our salesperson...very good salesperson), we will have a very good mattress for a long time. We have noticed that this new mattress has greatly improved our sleep at night. I'm so glad we spent the time to find the one for us. It's so important to take care of something that you spend 1/3rd of your life in. This has been a good investment...worth the expense. A good night sleep is vitally important!

Love this mattress for our King split platform! We've been sleeping soundly through the night since the very first night. It did seem a bit firmer compared to the showroom model, but our sales person said it would take awhile before it was broken in. But we slept right through the night at first and so how can we complain? We chose this series because of the hybrid combinations--mattress coils, foam and especially the cooling gel. We live in Texas and although we have air conditioning we do get hot as we sleep through the night. We are looking forward to the summer months to experience the difference and are expecting to be quite pleased. I had done a lot of research and hybrid seemed the way to go for best results.

First Time with a Serta | I'm Impressed

March 22, 2018


First time owning a Serta, coming from a Sealy Posturpedic Model - Plush Pillowtop. Looked into the idea of a all foam, but found the hybrid the best route to go. Naturally we looked at Sealy first, and after a few hours and multiple stores, we ended up trying every Sealy option our local stores had to offer. Then at the suggestion of a true and honest salesman, we tried a Serta and were immediately impressed. After some further explanation about Serta's Quality and some real world tests of our own, we found Serta to be the perfect fit for us in price, comfort,

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.

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!

Sleep in luxury

It took few days to break the mattress in, but now it’s like sleeping on a cloud. I like that it’s not all memory foam , but you get just enough of the memory foam feel.

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 a little skeptical at first because of the price. I have been wondering now what kept me from this mattress for so long. I love it.

I love this bed. I bought the iSeries 500 with an adjustable base. I did not know a thing about this bed before I walked into the store. I already had a price range set for a new mattress and had it picked out. My husband has wanted an adjustable bed for the longest time. Well he saw this one and was totally won over when he laid upon it. I tried it out and just like that, I changed my mind. We have both been sleeping so much better. I can't believe I waited so long to get one of these. We love t.

This mattress is replacing a two year old foam mattress. I developed some back pain about a month ago and found it hard to get to sleep. My wife suggested a firmer mattress may help. The first night on this new mattress my back felt much better. As the week progressed the nights were even better.

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.

I first slept on this mattress at my mother's house - and before that I never considered spending money on a mattress.. I never put thought into the difference it makes. I love the comfort and support of this mattress. Very well rested and feel great.

It was time to change our mattress and we saw a promotion for this mattress. It came in a box and was easy to install. It is very thick and light weight. I was surprised on how firm the foam mattress is. Had it for over a month and loving it.

This matttress is very well made, the sales people were great, the delivery was on time and painless. Our only concern is the firmness, it seems much firmer than the one in the show room and we hope it will become a little more comfortable over time.
