New Bed!

October 28, 2018

JULIES1540768384

I have enjoyed my first night on this mattress. It has the ability to remotely raise the head and or foot and that helps me out considerably with low back pain. It is comfortable and made me want to stay in it for hours on end! My dog ,all 100 lbs of him jumped up on it when i went downstairs, guess he sensed it was new and a big deal. My back pain decreased after one night !!

Best mattress we have had

After sleeping on a Tempurpedic mattress for 7 years, it was time for a change. I found my previous mattress to be too firm and always woke up in pain. This mattress has changed my life. Every night, I go to bed and it feels like I'm sleeping on an actual cloud. It is very plush, but offers the right amount of support as well. I wake up in the morning and always feel refreshed and energized. Another thing that I do enjoy about this mattress is the temperature. It is never too hot, which is really nice, since I normally sweat when I sleep. I find that I'm no longer tossing and turning, or having to rip the covers off myself in the middle of the night because I'm too warm. It really is a great change from my previous mattress. I'm typically a side sleeper, but have noticed that I can sleep comfortably in any position now, which is a big change. My husband also enjoys the mattress. He likes a firmer mattress, but finds this plush mattress to give him enough support to keep him happy. I've noticed he is a lot less grumpy in the mornings now! We both sleep really well. The price of this mattress is amazing compared to the other mattresses out there; it's just a really great value. We are very happy with it and recommend Serta to all of our friends and family members.

We have slept on this mattress for 3 months now. We went from a memory foam mattress to the 300 plush and I muse say it was completely different and so much better with the 300 plush it provides the right support for your body instead of allowing you to sink in the mattress like total memory foam does. Me and my husband both wake up feeling great he has suffered from back pain and our old mattress was making it worse but with our serra he hasn't been complaining with pain anywhere. It's is so soft and plush and keeps you at a comfortable body temperature all night long not to mention the material that covers the mattress is phenomenal!.There was so much tossing and turning at night trying to get comfortable on our old mattress but with the 300 plush we both get a healthy nights sleepand wake up feeling great. My mother slept on it as well during her recent stay and also said it is the most comfortable mattress hands down and is now going to purchase one. Thank you serta for such a wonderful mattress. This is no doubt the most comfortable supportive mattress we have ever owned. We have already recommended it to family and friends and will continue to reccomend the serta 300 plush to anyone seeking a new mattress.

I'd forgotten how a good nights sleep felt!

When the mattress was delivered I was still a little concerned that it was just one piece and not the traditional mattress and box spring that I've always used. Getting in the first night was a little difficult because it was different then what I've been sleeping on for the last nine years. When I woke up in the morning I realized I felt a little different. When I woke up the second morning I realized I felt good! I had a lot less aches and pains and I really felt good. I've had my new bed for a week now and I am truly amazed at the difference this bed has made in my life. Thank you Serta for showing me how important the proper mattress is and the wonderful difference it has made in my life.

Maximum comfort

Oh my this is the most comfortable bed I have ever slept on. When you lay down you are cradled in comfort. It is like sleeping on a cloud. This is the first time I do not wake up with back pain and the first time I just want to stay in bed. Not only is it comfortable but you cannot feel your partner 's movement. I am so pleased and would not hesitate to recommend and/or buy this bed again! Comfortable sleep really does make a difference... everyone should have this bed.

I have had a Water Bed for 26 years and it had a leak. I have a spare bed but its way to stiff for me, it is also a Serta. So I went in and asked Jace Steller which one would he suggest and he suggested this mattress. He was right.

Have enjoyed a Serta for many years, previously and the new mattress lived up to our expectations.

The new mattress improves over the previous Serta's comfort. Additionally, with the new adjustable base, my wife and I really achieve greater sleeping comfort and enjoy watching television in bed more than ever. This ISeries name includes "plush" and it truly is plush and comfortable.

Comfort and Individualized

January 21, 2018

We bought two ISeries 300 Plush Twin XL Mattresses to be installed on Rize Edge HT Adjustable Bases to make a European King Size bed. Dividing the king this way on the separate adjustable bases makes it possible for each of us to adjust the head and foot of our bed for personal comfort. The beds fit closely on the frames such that we do not notice they are separate beds. The ISeries 300 Plush has proven to be firm yet comfy ... not too soft and not too firm. Since purchasing this bed system, we are not experiencing the lower back aches we were having and since we both have medical conditions that require our heads be elevated, that problem has been addressed as well. We are very pleased with our purchase of this combination. We are both over 60 years of age. Please note that since your selection on my computer did not go beyond 54, I have stated the age correction here.

So Far So Good

February 13, 2018

I was reluctant to buy a true memory foam mattress because I didn't care for the feeling of sinking in when I sat or laid down. This mattress gives me support with that plush feeling that the other memory foams give. I immediately noticed when I lay on my side for an extended period that I don't feel pain. I used to switch from my back to my side all night long because I would start to feel pain in my hips. I no longer have that problem with this mattress. My hips and back feel fine. When my mattress arrived it was super firm and cold (it was February after all) but within a few hours it softened up. I did crawl on it as suggested in the brochure to get it to loosen and that seemed to help too. Some people complained of a smell. I did notice a little bit of a smell when they took it out of the bag but it was not bothersome. It just smelled new and dissipated very quickly. Even though it is supposed to have some cooling gels in the foam it still gets warm, but I wouldn't say hot. I did find myself looking rolling over for a cooler spot in the bed. So far I'm happy with this bed. and I hope for many more restful nights of sleep.

Super Comfortable

Very comfortable mattress. We purchased two (2) Twin XL mattress and and two (2) adjustable bases that have the option to raise and lower both the head and foot. Purchased this bed and I wondered why I did not purchase one long before this. The mattress has the soft feel desired but with firm support. The store manager - Ralph - knew his products and directed us to this mattress after listening to what we desired in a new bed. Sleeping much better than with a pillow top. Don't hesitate to buy. No problems here folks.

Firmer than expected, but still super comfy

May 11, 2018

I did a lot of research about mattresses on line and almost purchased 1I had never laid on! However before I did that I ended up at the mattress firm store. The mattress I used to own was incredibly soft almost too soft! It was really comfy, but my back was hurting all the time in the morning. I went in looking for another pillow top because I do like soft mattresses, and when I laid on those they were OK, but then when I laid on this I series 300 it just enveloped me and made me feel so supported! I went ahead and bought it then and there. Since I knew I could sleep on it for 4 months that helped in case I wanted to return it. I've had it about 3 weeks now, and when I got it it was much firmer than the one in the store! I do feel it is loosening up some sense I have been laying on it, and I have tried to lay in the middle and on the other side as well in order to loosen it up. I think that it will loosen up more as time goes on but either way I do feel more supported, my back does not hurt nearly as badd every morning , and if you lay in one spot for more than 3 or 4 minutes you do sink in and it feels soft which is what I like I think I'll hold on to it for a couple more months before I make a full decision and see if it softens up like the one in the store, but so far I think I like it!

I am not sure that I am sleeping on the same bed as the previous reviewers

I am not sure that I am sleeping on the same bed as the previous reviewers. I purchased my Blue Fusion 300 Hybrid from Bernie and Phylls. I shopped for over one year and was explicit that I wanted a comfortable bed that would work with an adjustable base. I was sold the Ease 2.0 as the foundation. It was suggested that I acclimate to the new mattress for 30 days but it seems to get worse each night. I purchased the Queen size and I sleep alone. This bed is not comfortable. I find myself sinking in the middle and every morning I wake with back aches. I wouldn't mind as much if this were one of the lower end mattresses considering that you get what you pay for. However, for me $1300 is a lot to pay for just a mattress and to be so uncomfortable at night.

Amazing Sleep

September 27, 2018

JohnL1538061732

I have had a waterbed for 36 years, which I love sleeping on, but I'm getting too old to be able to adequately maintain it. I really was worried about not being able to sleep on a non-waterbed, but I looked at other mattresses anyway. The iSeries 300 Plush mattress is amazing! I sleep on it just as well as I did on my waterbed! I'm actually surprised at this, but very pleased!

There is not much i do not like about this mattress at all, the only thing i wish was that the regular metal frame was a little better made. I am building my own head board for both beds. (I bought a queen for me and a Full for my son). But since i am building my own headboards for it, i only wanted to purchase the metal frame for both beds. They are quite a bit flimsy for the price, i will have to look into getting a couple more better made frames, but as far as the mattress goes, this is probably the best one i have ever purchased. Now it is only a couple months old, so we will see how many years i get out of it before i need another one, but i feel if i can get at best 6 to maybe 7 years, i have more than got my monies worth. So i got my fingers crossed on that one. I have bought way more expensive ones in the past and i can tell you that i will be a full time Serta mattress buyer from here on out if they hold up. The more expensive ones that i have purchased in the past was not nearly as comfortable as this one. And the old one was just wore out, but now i sleep like a baby!!!!!! I just wish they would have thrown in a couple nice pillows with them, as much as i paid a couple pillows would have been nice. But that's ok! I will only buy serta in the future!

Perfect for those with bone pain

When I first bought this mattress al ost 7 years ago it instantly removes my pain. Completely removed it, where even pain medication didn’t help. I was amazed that a mattress could improve my quality of life so much. It’s been a dream of a mattress until this year. I admit, I expected it to last longer, however in reality a dreamy sleep for 7 years is better than typical mattress comfort. So overall I am content with the mattress. Now that I am in market for another, I will be reviewing this brand since I know I love their comfort.

Best sleep I've ever had

May 8, 2017

I am not exaggerating when I say that this is the most comfortable mattress I've ever slept on and I've owned many different mattresses and mattress toppers in my life. This bed is soft yet very supportive. My husband has had back problems his entire life from a childhood injury, and after just a few nights of sleeping on this mattress, he told me that his back wasn't aching like it usually does. The Serta iSeries 300 Plush will be worth every penny you spend on it, and no matter how hard I've tried, I can't find anything I don't like with this mattress. When laying on this bed, you will not feel any pressure in the usual pressure points, and would be great for anyone who has any soreness in their joints (wish I would have had this when I was pregnant last year). I did not realize how much I woke up tossing and turning and how much I tossed and turned while trying to fall asleep until I got this mattress. I can tell that the quality of my sleep improved 100% and I can now fall asleep within minutes instead of my usual hours it used to take. This mattress is soft and plush but also has the right amount of firmness that creates great support. I should also note that my husband and I are overweight (around 300lbs) and it provides amazing support. This mattress is also quiet, which our old mattress lacked and often woke up our newborn. The top has a cotton top which makes it very comfy and soft to sleep on rather than the standard mattress top that is silky and plastic-feeling.
