BUYER BEWARE!! SERTA DOES NOT STAND BEHIND THEIR WARRANTY!!!!

November 14, 2018

DA1542217947

After 3 months of sleeping on this over $1000 mattress, one side of mattress lost its firmness!! If you get too close to the edge of the bed it gives out and you will roll right out of the bed. Called place where we purchased it and they sent out a company called Precise Mattress Inspection!! They are a total joke!! Also, beware of them!! The notes he wrote on the inspection were NOT what we said. Serta denied our claim because of this inspection. Called Serta and they will stand by the inspection because the pictures didn't show an impression!!! Well, come and lay on it then tell me there is nothing wrong with it!! Pictures don't show the frimness gone!! Very very disappointed in this mattress and the way Serta is handling this so called inspection!! We DO NOT recommend this mattress to anyone!!

Firm and comfortable

I selected this mattress because we were looking for something on the firmer side. The old mattress was 10 years old and giving me back pain. The back pain has definitely improved. I like the mattress. There was no outgassing or any weird smell so that was good. I hope that the mattress holds up over time as I do like the firm support that it is providing.

So comfortable, worth the price

I found I sleep better in my new mattress. I can sleep the whole night thru and wake up rested, before my alarm clock and in the same sleeping position from the night before. I also fall asleep faster than I ever have. I don’t feel the mattress gets hot either. The first few nights I was doubtful that it was actually near the time I needed to wake up. So glad I made the decision to get this mattress. I like a firm but softer mattress and this was a perfect fit. I no longer have to have a bunch of pillows on the bed to get comfortable. The kids have also been sneaking into the bed to take a nap. Very satisfied with my purchase.

Great quality if you like a firm mattress.

The Blue Fusion 100 Firm mattress is a high-quality mattress. With that being said, it is also a very firm mattress. Yes, I do realize that it says 'firm' in the title. My husband has had back surgery and I did some research and read that for his condition a firm mattress would be best. My mistake came into play when I didn't take into account that I am a side sleeper. My husband (a back sleeper) found this mattress incredibly comfortable, however, no matter what I did, I could not get comfortable. It was hard to rate as my comfort level would be a 2, but my husbands would be a 5. The quality of the bed is superior. I am now in the market to find a better fit for the both of us. I will definitely be looking for another Serta.

Best mattress ever

October 5, 2019

DannyA1570249156

I love this mattress and am buying more. Granted, I hated this mattress for the first three months... I was convinced I would send it back. There was a 90 day requirement first and I knew up front that 90 days should give me time to adjust... if possible. Well? I adjusted for sure. Now it hurts my back to sleep on anything else! I spend time in two different towns and I am so tired of the mattress issue over there that I am about to buy another of these and put my chiropractor on notice: I have had this blue fusion for 1 year and 2 months. I love it. I got the fancy electric platform with vibrator and all. I may save that expense but the mattress I can not do without!

I highly recommend the blue fushion 100. We were interested in upgrading from a full to a queen and thought the hybrid was the perfect combination for us.

It was like sleeping on the cement sidewalk

I have a bad back and my previous mattress was sinking in the middle. I purchased this mattress after testing it against several other mattresses in the store. I managed to sleep on this mattress one and half nights before resorting to sleeping on my futon sofa in my sunroom. I cannot describe the level of pain I was experiencing after trying to sleep on this mattress the first night. It in no way provided the same comfort I got in the store. I assume this has to do with the store demo having been broken in by the numerous customers who have tested it out. The second night (half night), I cushioned it with a padded mattress cover, a memory foam topper and several quilts/blankets to no avail. It is like sleeping on the cement sidewalk. My mattress was delivered on a Saturday and Monday I called the store and returned it. I selected a different Serta mattress with padding and I am currently waiting for its delivery. I'm hoping for better success!

The edges don’t collapse when you sit on them. The sleeping surface is firm yet very comfortable even for a side sleeper like me. During my research I tried many retailers and brands but Serta Direct was the best choice for me. When I purchased directly from Serta I was very pleased with customer service and delivery.

Amazing Mattress

After going through two Simmons Beautyrest mattress in the past 14 years, due to the mattresses sinking in, this mattress feels like a dream. It conforms to mine and my husbands bodies which makes it very comfortable to sleep. The mattress is listed as firm but has the comfort of a foam mattress. My children have Serta Mattress, we fell in love with their mattress and had to get one too. We are excited and thrilled about our Serta Blue Fusion 100 mattress!

Buyer beware.

I weight 190lbs, rotated this mattress monthly and ended up with crippling back pain after 9 months of use. Due to excessive sagging. Which is not visible as it is a pillow top however place the slightest pressure and you will find a crater. I attempted to have the issue resolved by Haverty's where i purchased it. They brought a weightless wooden block, said its not below 1 1/2 inches, sorry for you. My wife's side wasn't as bad but had begun to deteriorate. Unless you are buying it for a child, i would look elsewhere.

The iComfort Blue Fusion 100 hybrid works for us (we bought 2 twin size). My husband has a bad back and needed a firmer mattress; by choosing this mattress he is sleeping well and his back seems better. Also, I notice that I'm not so stiff when I wake up in the morning. We feel we made a good choice for both of us!

The worst mattress

May 27, 2019

JennaJ1558969877

You couldn't GIVE this mattress to me. A lot of money later and we're stuck with this rock of a mattress that makes all body parts that have any contact with it for longer than 5 minutes fall asleep or go numb due to the extreme firmness. What's bad is I did my research and everyone said it was soft enough yet firm for back support which is what we were looking for. We will now have to spend more money to buy a topper so we can actually sleep throughout the night. We have been sleeping on it for about 60 days now and it hasn't gotten any better yet.

AFTER SLEEPING ON MY NEW SERTA FOR THREE WEEKS IT HASN,T DISAPPOINTED ME IN THE SLEEP COMFORT. IT WOULD HAVE MET MY TOP RATING EXCEPT I NOTICED THE TOP FABRIC STITCHING PULLING LOOSE IN SOME AREAS. OTHERWISE THE QUALITY APPEARS EXCELLANT. THE NEW HYBRID CONSTRUCTION PROVIDED A MORE COMFORTABLE FIRMNESS THAN MY OLDER MATTRESS.

When we first received the mattress it was a little firm. But after a few weeks it softened up but is still firm, which is what we wanted. The medium beds were to soft. This mattress has great support. Great price and we’re looking forward to counting some sheep and getting a great nights sleep! Go try it for yourself!

I love this mattress sleeps very well, however my husband because he has back problems is a little disappointed. He feels the support of the mattress and quality should have been better for his situation and that the sales person where we purchased should have been more qualified to know this.

At first I didn’t look at this model because it is labeled as firm and I’ve always had plush mattresses. The mattress provides a lot of support but is very comfortable and cushions you in the right places. There are no indentations or sagging. I bought the adjustable base as well and I couldn’t be happier. I highly recommend this mattress.

Serta Hybrid Mattress

DavidW1559219943

First two nights on the mattress have gone well. Both my spouse and myself found this mattress as a good fit, not too firm, not too soft. While the mattress is rated as firm, it feels like a luxury firm to us. We chose a hybrid to get introduced to memory foam, but still keep feel of coil spring.
