Product Overview

Bring the relaxing vacation feel into your home thanks to this Beautyrest Hotel Diamond 4.0 hi-loft pillow-top king mattress from Simmons. Built with two layers of pocket coils, this bed supports every body part for the best sleep you could want. An ergo comfort layer features both latex and viscose to cradle you as you rest. Meanwhile, four inches of gel-infused AirCool® foam provides a relaxing space. With AirCool BeautyEdge® foam encasement surrounding the coils, feel free to stretch out every which way.

This sleep set includes one mattress and a low-profile split boxspring. Made from two smaller boxsprings, a split boxspring provides the same support as a single boxspring when used together yet is much easier to manoeuvre through tight spaces. Low-profile boxsprings sit further down on your bed frame to help lower the overall bed height, making it easier for those with physical limitations to get in and out of bed.

  • ErgoSupport System Featuring 1,800 Pocket Coils
  • AirCool BeautyEdge® Foam Encasement
  • CrispClean Antimicrobial Fabric Protection
  • Ergo Comfort Layer with Latex and Viscose
  • AirCool Comfort Foam with Gel Layer
