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!

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!

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.

Super Comfy and worth it

November 25, 2018


I can sleep for hours on end without becoming sore or restless. Its like an infinite recovery. Mind you Ive only owned the bed for barely a month now, and I know it takes months to reap the rewards sometimes but myself and my fiancé already feel a difference in our lives. Mornings are easier, the days are better, workouts are fiercer, and no kinked joints or muscles. Definitely worth it and would highly recommend to others!

Amazingly comfortable. Best sleep in years.

January 3, 2019


I've been looking for a mattress for a while. The information can be overwhelming, but after trying this one at the store, I thought I couldn't go wrong. The price was reasonable. Once installed and I went to bed it took me a few nights to get use to the comfort. Weird but after that I haven't slept so well like this in years. Great product!

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,

Great mattress but sightly too firm

April 8, 2018


My wife and I needed a new mattress and this hybrid ISeries 500 Plush is a great mattress. We have been sleeping on it for over a month and it is a bit too firm for our liking. No major issues with this mattress other than preference for something slightly softer. Great back sleeper, not so great for side sleeping. Still wake up with sore/tingling shoulders. My wife wakes up with sore hips. We are likely going to use our 120 day sleep trial to trade in for a slightly softer Serta.

Quality mattress

We upgraded from a iseries queen which was about 7 years old to a king mattress. The bed is fantastic as was our salesman, Jerry. Looking forward to many years of great sleep.

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.

Misleading softness label

December 23, 2017


This mattress is described in specs as in the middle level of support. One would think that means: Not too hard. Not too soft. Well that’s simply not the case. It is very firm for someone expecting middle-of-the-road support. Even with the 4 inches of memory foam, the springs’ tension make the bed firm. I don’t recommend this bed if you know you don’t like firm beds.

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.

Love this mattress

July 1, 2018


incredibly comfortable and great value. We did get the adjustable base and opted for the single unit on a king size mattress. In hindsight I would have purchased separate adjustable bases, but overall very pleased.

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.

August 5, 2018


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.

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!

Comfortable bed

November 30, 2018


At first I wasn't sure about the mattress, we tried it in the store with the cooling feature and it felt slightly different. We've never had a memory foam mattress but wanted to get one this time because we thought they were the most comfortable ones we tried. The first couple nights my arm kept falling asleep because I wasn't used to it but now we sleep great. It's also nice because when one of us gets up from the bed the other doesn't feel it. The only thing I am disappointed in is like I said it feels slightly different than the store one we tried out with less cooling.

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.

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!
