Balanced Feel, Mid-Range Performance

by Jed Harrington

The Beautyrest BRS900 Plush King Size Mattress is among the top all around comfortable options from the collection. It has a not too firm and not to soft level of comfort, plenty of lower back support, and certified comfort components made to offer great sleep without breaking the bank.

Comfort and Support Are Truly Balanced

The BRS900 Plush offers the best of both comfort and support. Scoring a 5 out of 10 on our Comfort Scale (10 being the softest), this mattress falls into the not too soft, not too firm category. It has a good blend of solid underlying support, body contouring, and pressure relief.

Cleverly Designed Pocketed Coil Technology

The individually pocketed coil system delivers exceptional body contouring, good pressure relief, and solid support. It's also really good at minimizing motion transfer, so you can continue to sleep undisturbed when there’s movement.

Designed for Cooler Nights of Sleep

The DualCool Technology used in the quilt is an antimicrobial performance layer that keeps your mattress fresh and cool, and it also wicks away moisture to create a comfortably cool sleep environment.

Bolsters Lower Back Support

Gel Memory Foam Lumbar Support ensures reinforced support and durability to the lower back, supplying plenty of support where you need it most.

Is This Mattress the Best Choice For Your Needs?

If you don't necessarily want all the bells and whistles and enjoy a balanced level of comfort, the Beautyrest BRS900 Plush King Size Mattress makes a fine choice. The solid construction, coil system, and certified comfort materials all come together to provide a great value. It's dependably made and comes complete with a generous 10-year warranty to ensure you’re satisfied with your purchase.
