Serta iComfort Blue 300 CT Plush Mattress Review

Serta iComfort Blue 300 CT Plush lifestyle - mattress in a room

The Blue 300 CT Plush is a medium-firm feeling iComfort mattress. It's a bit softer than its sister model, the Blue 300 CT Firm. Our team tested each and every Serta iComfort model at our facility and you can see the results and our review for the Blue 300 CT Plush below:

Comfort Scale Rating

The Blue 300 CT Plush mattress is a medium-firm feeling bed that we rate 4 on our 10 point Comfort Scale (a 1 is hard, 10 is softest). This rating will appeal to a broad range of people. It's a nice compromise between partners, and anyone will like it as long as they don't have a strong preference for very firm or very soft.

Pressure Test Results

We brought the Blue 300 CT Plush mattress into our building and pressure tested it with small, average and large body size people on their sides and back sleeping positions. We do this to give you an idea of what kind of support and comfort you can expect. (Learn how we test.)

The Blue 300 CT Plush mattress had good results for all body sizes and sleeping positions. It provided decent support and there are no spots of excessive pressure. The conforming foams used really help to distribute weight evenly, which is what gets these good results.

Conclusion

The iComfort Blue 300 CT Plush is a medium-firm feeling bed. A mattress with this firmness will appeal to most.

Results showed sufficient contouring to relieve pressure points. There was a good amount of support provided, which is important to ensure you have proper spine alignment. That's what'll prevent morning back pains. We gave the mattress mostly ‘Good’ ratings for 4 of 6 sleeping positions, and the other two were 'Recommended'. So, it's quite good overall and will suit just about anybody.

It’s a mid-priced mattress from iComfort ($1,499 queen-size). If you wanted to consider increased premium foam layers then Serta’s Blue Max 1000 Cushion Firm is available for $300 extra. What's most important is that you figure out what works best for your individual needs.
