The Serta Perfect Sleeper Select Kleinmon II Firm Size Mattress is one of the best overall options in the Perfect Sleeper collection, so long as you prefer a very firm comfort level. This mattress belongs to the second generation of Kleinmon models and includes many of the same features found in last year’s line, but at a more affordable price.

Incredibly Firm Level of Comfort

If you’re after a very firm comfort level that’s almost hard, the Kleinmon II Firm is a great option. With a score of 1.5 out of 10 on our Comfort Scale, with 10 being the softest, this kind of comfort feels similar to a carpeted floor.

Equipped With Highly Praised Coil System

The 880 Edition Custom Support IWC coil system contains a series of individually wrapped coils to deliver a high degree of body contouring, while maintaining solid support to the lower back. This system is compatible with adjustable bases and designed to keep motion transfer at a minimum for undisturbed rest.

HyperTouch Comfort Eases Pressure Points

The HyperTouch Comfort System is included to maximize pressure relief near the top of the mattress where it’s the most important.

Feel Less Movement For Better Nights of Sleep

Frequently incorporated when making premium models, Cool Twist Gel Memory Foam promotes deep, rejuvenating rest through superior pressure relief.

An Amazing Value

If you’re on the lookout for a mattress that has a great combination of performance and a good price point, the Serta Perfect Sleeper Select Kleinmon II Firm is a great choice, as long as you like a very firm comfort level.
