SleepingPeacefully

Ahhhhh

Date:January 12, 2013
Pros: Great value, High quality
This mattress is a life saver. After the first night's sleep, I realized how bad and dangerous my old mattress was to my back and health. The next morning I woke up refreshed and energized, I slept straight through the night and felt that I had rested, instead of just laying down.
The delivery was on the date promised and within the stated times. The set up was efficient and quick.
This is the best purchase I have made in years.

SurgicalRecovery

So much better than previous mattresses!

Date:January 10, 2013
Pros: Great value, High quality
I recently had back surgery and have had 2 matresses that within a month of each other started to sag as soon as I brought them home! I then went out and purchased this matress and wow! What a difference! Definitely a firm mattress so those looking for something soft or plush this is not for you! My bf and I are bigger people and there is no sinking feeling or sagging and the sides of the bed are even holding up very well. I spend a lot of time in my bed due to recovery and it is still amazing!

Quietly Comfortable

Date:December 10, 2012
Pros: Great value, High quality
I never realized how noisy my old mattress was until we got our new Iseries Firm/Serta mattress & boxspring. My daughters pointed out how they used to know when we got up by the noise our bed made, we had blamed the noise on our frame. I still expect to hear noises as I move my position, or when my husband gets up for work.
The encased edge support was another eye opener. With my old mattress I would actually grab hold of a spring to pull myself up and out of bed. You could see the spring sticking out. Now I have nice firm support all around the bed, I can push myself up just by placing my hand anywhere on the mattress, nothing gives away, there are no weak spots.
We are now on week three, and I can honestly say I'm thrilled we made this purchase. We get a great nights sleep, it's quiet, and well constructed. Our old mattress/boxspring was only 5 yrs old. Somehow in that time , we thought it was normal or ok for a mattress to be noisey, lumpy, and coils easily within reach.
My husband and I now look forward to being in this bed for as long as the warrenty allows.

Best night's sleep

Date:October 10, 2012
Pros: Great value, High quality
I had a mattress where I was unable to sleep and swapped it for this one. It is more expensive, but the old saying that you get what you pay for is so true when it comes to getting a good night's sleep. It just wasn't worth the savings on the prior mattress and since getting this new one, I feel so much better. Definitely worth a trial; you'll never go back!

very good purchase

Date:September 26, 2012
Pros: Great value, High quality
This mattress is the best of both worlds. Top Layers of foam and coil in coil springs. Ideal for folks with back and neck pain. One of the most comfortable mattresses I have ever slept on. For the first time in years, I feel refreshed and well rested in the A.M.
I have recommended this mattress to my friends and family.

GREAT MATTRESS!

Date:September 7, 2012
Pros: Great value, High quality
We purchased a mattess at Sleepy's to save a little money and it wasn't quite right. We exchanged for the one I originally wanted, the i-series. My husband and I have back and other health issues. Well, ever since this mattress set has been delivered, I can honestly say, we are sleeping great and no pain. It's unbelievable! This is by far, worth the investment! What a great mattress! Thank you Sleepy's and Serta!

Pros: High quality
This mattress is ideal if you sleep best on a firm bed. Support is uniform along entire length of your body. The gel memory foam remains cool while providing a soft feel to your body.

So far very happy with purchase!

Date:July 22, 2012
Pros: Great value, High quality
Coming off of having a Simmons beauty rest pillow top for 9 years, which has literally killed my back since we first got it, And we just kept put off getting a new mattress, until now. I know I needed something firmer since our last mattress lacked in support., which has led me to this particular iseries flattery firm. In the show room, when I layer on this bed, I knew I had to have it! It was firm yet cushy at the same time, hence the gel foam memory and innerspring all wrapped up in one mattress! I'm hoping my back pain gets better in time sleeping on this new bed!
