If you want an extra firm mattress, this is perfect

by Jed Harrington

The Serta iComfort Hybrid Blue Fusion 500 Extra Firm California King Size Mattress is the most firm choice in the line, so it’s worth considering it isn’t ideal for everyone. If you want something that has an exceptionally dense level of comfort, keep reading, because this mattress is full of great features designed to provide years of comfort and support for someone who prefers a firm feel.

Impressive comfort materials produce a dense comfort level

Using the latest in high end comfort materials from Serta, the 500 Extra Firm creates a combination of contouring and temperature control. TempActive Gel Memory Foam and Deep Reaction Max Memory Foam are the main materials, easing pressure points and ensuring long-term durability.

Scoring a 2 out of 10 on our Comfort Scale, with 10 being the softest, this mattress is one of the firmest choices offered in the line. You can expect a really dense overall feel with this choice.

Brilliantly Designed Technology Manages Temperature for Comfort

TempActiv Gel Memory Foam incorporates an innovative phase change material to pull heat away from the surface, ensuring you can enjoy cool comfort while you drift off to sleep.

Improved coil system guarantees top-of-the-line Serta support

The Serta Hybrid Coil Support System successfully combines body contouring comfort and solid deep down support. With a unique design that resembles a soft serve ice cream cone, it features a spiraled top.

The top part is constructed to create better body contouring, while the middle is significantly wider to provide support that is exceptionally firm. It’s conveniently compatible with an adjustable base, and it even decreases transfer of motion to ensure you enjoy sleeping without any disturbances.

Foam Encased Edge Support System Keeps Comfort Consistent

This mattress incorporates the BestEdge Foam Encasement, so resting close to the edges is nothing to worry about. If you’re someone who tends to move a lot while you’re asleep, this feature will be an especially nice feature for you because comfort is the same all the way from edge to edge.

Is this model the best option available for your needs?

Our testing of this mattress resulted in wonderful results for back sleepers with average body types and good results for all other back sleepers. This mattress is not designed with side sleepers in mind because, as with all extra firm models, it can produce some pressure on the hips and shoulders. Unless you are used to this type of feel, I would suggest going with something softer. You can experience the results of our testing here: See how this mattress performed.
