If you’re on the lookout for an extra firm mattress, you’ve found it

by Jed Harrington

The Serta iComfort Hybrid Blue Fusion 500 Extra Firm King Size Mattress is the firmest option in the line, so it’s important to realize it isn’t ideal for everyone. Although, if you want something that has an incredibly dense overall feel, keep reading, because this mattress has many great features designed to provide years of comfort and support for someone who prefers a firm comfort level.

Luxurious comfort materials offer a very dense comfort level

Made using the latest high end comfort materials from Serta, the 500 Extra Firm creates a combination of contouring and temperature management. TempActive Gel Memory Foam and Deep Reaction Max Memory Foam are the main materials that help to ease pressure points and ensure durability.

Scoring a rating of 2 out of 10 on our Comfort Scale, with 10 being the softest, this mattress is certainly among the firmest available in the line. You can expect an exceptionally dense overall feel with this option.

Superior Technology Manages Temperature for Comfort

TempActiv Gel Memory Foam uses an innovative phase change material to pull heat away from the surface, helping you rest comfortably while you drift off to sleep.

Recently upgraded coil system ensures top Serta line support

The Serta Hybrid Coil Support System boasts an ideal blend of body contouring comfort and solid deep down support. Its unique design resembles a soft serve ice cream cone with its spiraled top.

The top part is engineered to create better body contouring, while the middle is significantly wider to give your body firm support. It’s conveniently adjustable base compatible, and it even decreases transfer of motion to ensure you can enjoy undisrupted rest.

Foam Encased Edge Support System Brings Consistent Comfort

Thanks to the inclusion of the BestEdge Foam Encasement, resting close to the edges is nothing to worry about. If you’re someone who tends to move a lot in your sleep, this feature will be an especially nice feature for you.

Is this mattress the top choice out there for you?

Thorough testing of this mattress resulted in excellent results for back sleepers with typical body types and good results for all other back sleepers. This mattress is not designed for side sleepers because, as with all extra firm models, it can produce some pressure on the hips and shoulders. Unless you’re used to this type of comfort, I would recommend going with something softer. You can see the results of our testing here: See how this mattress performed.

Physical Characteristics

Comfort This describes how a mattress feels. The Comfort Scale rating is based on how the cushioning materials conform to the body's shape. The higher the number the softer the mattress.

Quilt - Top of Mattress This is the outside cover on the top of the mattress. It covers and protects the comfort and support layers inside.

Comfort - Padding Layers This provides a cushioning layer between you and the support system in the bed. Different kinds of padding will provide different levels of comfort.

Correct Back Support System This is a general term used to describe how a mattress distributes and stabilizes body weight and maintains proper spinal alignment. Different materials provide different levels of support.

Box Spring - Foundation (optional)

Warranty This tells you what kind of warranty you have and how long it will last. A typical warranty lasts about 10 years.
