Take a Look Inside

Foam Support Base

One-inch of high-density foam for a robust and resilient foundation that supports all shapes and sizes. When flipped up, this also serves as the “firmer” side of the mattress base.

Highlighting the coils on our oversized Grand Slumber Hybrid Mattress.


Thousands of heavy-duty individually pocketed coils for reduced motion transfer and active support. Fabric-encased for greater durability.

Pink Foam

A unique combination of soft, comfortable cushion with high-density durability for long-lasting support. Get the hug and bounce you need with this exclusive foam layer. When flipped up, this conforming latex-like foam acts as the “softer” side of the mattress base.

Naturally derived latex in the topper bolsters pressure relieving benefits by increasing durability and responsiveness. It reduces sinking into the mattress and guarantees smooth transitions while you sleep.

Cooling Memory Foam

The memory foam in the topper offers a blissful initial feel. It provides pressure relief for hips and shoulders without leaving impressions. Also eliminates motion transfer. Cooling properties keep you from sleeping hot.

Additional Information

  • The dimensions of our different Grand Slumber Hybrid Mattress sizes are:

    • Wyoming King: 84” x 84”
    • Texas King: 80” x 98”
    • Alberta King: 96” x 96”
    • Florida King: 108” x 80”
    • Alaskan King: 108” x 108”
  • Grand Slumber Hybrid Mattresses ship independently from our bed frames. Mattresses will be scheduled for delivery within 3-5 business days of your bed. If your mattress is ordered without a bed frame, it ships out immediately.

    The Grand Slumber Hybrid Mattresses are delivered in three (3) separate boxes.

    Mattresses are not delivered by our White Glove Delivery partners. If you order White Glove Delivery for your bed frame, your Grand Slumber Hybrid Mattress will still arrive on its own.

  • Our Grand Slumber Hybrid Mattress offers the ability to adjust for a softer or firmer sleep experience. Simply flip the base section of the mattress. Then reattach the topper to the side that you will be sleeping on. When flipped up, the Pink Foam side of the mattress provides a softer cushion. When reversed with the Foam Support Base of the mattress facing up, you’ll get a firmer feel.

  • Our oversized bed frames are designed so that you will not need to use a box spring to support your mattress. The mattress rests on durable 2x4 and 2x8 wooden slats. We recommend placing a solid surface between a memory foam mattress and the wooden slats. All Grand Slumber Hybrid Mattresses ordered with a bed frame automatically ship with a ⅛” masonite board. This keeps the foam-based mattress from sinking between the slats over time.

  • We understand that great sleep is an important investment for anyone. To ensure that your Grand Slumber Hybrid Mattress lasts a lifetime, we offer the ability to buy and replace just the topper. This allows you to continue using the same mattress base while still refreshing your sleep experience over the years. Contact us for more information.
