First Time Owners of Memory Foam Mattress

It was time for a new mattress for us so we went to Mattress Firm (which had great online reviews) to buy a mattress. With the advice of Allen, we purchased the Serta I Series 500 mattress and absolutely love it. We also purchased an adjustable bed frame which is a great combination with this mattress. Highly recommend both and the Mattress Firm Store as well (in San Diego, CA)

This mattress is the perfect blend between foam and traditional. Allows the mattress to conture to your body where it needs, with the perfect amount of pressure relief. Although it may seem too firm for some at first, within the first few weeks your mattress will break in and adjust to your body making great for all combo sleepers like myself.

Replaced other brand King, down to Queen - Serta products well made, great workmanship, pleased with mattress height. Better sleep after only a few days. Great information from sales clerk, attentive to our needs and final decision.

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!

Comfortable bed

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.

We bought a split king iSeries 500 to replace our 14 year old Serta Perfect Sleeper that we thought was much too firm, even after all the years of use. We were surprised to find that we ended up choosing another mattress labeled as a firm but it's much less firm than most other firm mattresses. It was frustrating to find so few "middle of the line" options as far as firmness. It was either plush or firm. I feel like this one was in the middle though. Still a tad firm but not like the others. I would have appreciated more medium firmness options. We do sleep more comfortably and don't roll over as much as before.

It will give me the confidence to know I won't be purchasing another for a long time and getting the rest I need.

We purchased the iseries Hybrid 500 Comfort Firm Mattress, and it was an expensive purchase. The showroom mattress was pure heaven, but the bed we received, not so much. It is far too firm, and I really dislike it. I went to the store and told them of my issue. They said it takes a while for the mattress to fully "expand" because it has been sitting in a warehouse, in plastic, all compressed. They said to give it 30 days. I am very unhappy with it, so far. I will come back and update my review when I feel like I am sleeping on the mattress I thought I was purchasing. So for now, I am having the worse sleep of my life. If it does not get better, I will be returning it and demanding a full refund.

No PRESSURE Points!

I love this product because Consumer Reports magazine gave it an excellent rating. This bed is ideal for how we sleep at night and how good we feel in the morning. Both of us are side sleepers' and back sleepers' and have felt comfortable every morning. My wife and I are not tossing and turning all night because neither of us are getting pressure points pain with our new mattress. It was well worth the extra money to get a good nights' sleep. I wish I had done this many years ago.

We are pleased with this mattress which replaced a 10 year old Tempurpedic. The mattress provides consistent firmness with a soft touch. I am comfortable on my back or side.
