My Review of The Serta icomfort Blue 300 CT Firm Queen Size Mattress

by Jed Harrington

The Serta iComfort Blue 300CT Firm Queen Size Mattress is a fine example of a re-release done well. Serta created a solid product that excels at pressure point relief, cooling, and body surface area coverage at a price point that's lower than the competition.

Firm Overall Level of Comfort

The Blue 300CT has a very solid feel, but it still supplies good pressure relief. If you're a back sleeper and like a firmer feel, this mattress is going to be a great choice for you.

High Quality Serta Foam Support Core

The Serta Foam Core provides solid support to the lower back while dampening motion transfer and works particularly well with the memory foam comfort layers.

Utilizes Superior Comfort Materials

Deep Reaction Max Memory Foam and EverCool Fuze Gel Memory Foam work with each other to provide phenomenal pressure relief, a firm level of comfort, and exceptional motion reduction for undisturbed sleep.

Comfort That's CertiPUR US Certified

The TempActive Touch Cover provides a cool to the touch feel that regulates body temperature for cooler nights of sleep.

An Exceptional Premium Mattress

In the firm mattress category of premium mattress, it's hard to outdo the Blue 300CT Firm. In testing, this mattress scored amazingly well for back sleepers and side sleepers of all body types. It feels solid, provides great pressure relief, sleeps cool, and has a nice edge support. It comes with everything you need to start enjoying deep, restful sleep.

Slept well in it the first night.
Slept well night one. Did notice that the bottom sheet gets out of place more easily because of raising the head. They are new sheets. With a broken leg, this seems to be the answer.

Love our new mattress!
It's a very firm mattress, but that's what we were looking for.

Best Mattress
Finally after 3 different brands we tried we find the perfect mattress for us. Just this year. All known brands. One was 12in memory foam but seems too plush. We felt sunken in and made us sweat. Second was firm but too firm. Every side we layed on went numb. And for both we work up with back pain. This one the serta 300 ct firm is amazing. No over heating for us. It has the comfort of memort foam but with a firm top so our bodies are evenly sleeping yet still soft comfortable. No numbness which is great. We dont wake-up adjustting our sides like we used to. I can say enough great things. Were elated to finally get a whole nights sleep. Wish we would gone with this brand first. But we were being cheap. And cheap gets you cheap product. At the end we wasted more money buying wrong mattress and waking up in pain. Absolutely worth it every penny. A mattress ahould be the product we focused on quality more. Now I know this and I will not be buying any other brand. Serta is the best.

The serta blue 300 ct firm is amazing. It took about a week or two to notice the difference but oh my god I feel the difference and I love it. It’s very comfortable once you lay down you don’t want to get back up. Definitely recommend for people who have pain in their backs like me .

One of the best choices ive made!
My husband and I had just got married so we figured we would buy and invest in a bed that would last us a long time. Serta offers so many different beds that suited our needs but this one came out being the winner. It offers qualities that I look for in a bed as well as my husband, the memory gel is amazing for those warm nights because it keeps your body cool. We decided to go with the firm because I really enjoy firmness yet my husband enjoys a little bit on the softer side! This bed worked out great for both of us regardless of our differences when it comes to qualities in beds. My in-laws offically want one!

Fell in love at first sight. I’ve had amazing sleep since receiving this beautiful mattress. I hadn’t had a decent night sleep in years. The memory foam is like sleeping on a cloud. My back has never felt so good. I would recommend this mattress to everyone. Thank you for reminding me what a good nights sleep is
