Who This Is For

If you’re a side sleeper who struggles with shoulder or hip pain, the Classic 12 inch King Mattress provides the cushioning needed to relieve pressure points while still offering support. You’ll find that the memory foam helps to align your spine and keep you comfortable all night.

For back sleepers looking for a balance of comfort and support, this mattress is designed with a medium firm feel that keeps your back aligned without feeling too rigid. It’s a great option for anyone who doesn’t want to sink too deeply into their mattress.

Lastly, if you’re a couple sharing a king size bed, you’ll appreciate how this mattress minimizes motion transfer. So if your partner shifts or gets up during the night, you won’t be disturbed.

Key Features

Contouring Memory Foam

This mattress utilizes high-quality memory foam that conforms to your body shape, providing tailored support. It helps alleviate pressure points, which is especially beneficial for side sleepers. You’ll notice less tossing and turning, leading to a deeper, more restorative sleep.

Cooling Top Layer

Equipped with a special cooling layer, this mattress regulates your body temperature throughout the night. It pulls heat away from your body, so you won’t wake up sweaty. Ideal for those who tend to sleep hot, it ensures you stay comfortable all night long.

Medium Firm Feel

The medium firm design strikes a perfect balance for various sleeping positions. It’s supportive enough for back sleepers while still soft enough for side sleepers, making it versatile for couples with different preferences. You won't have to compromise on comfort.

365-Night Trial

This mattress comes with a generous 365-night trial period, allowing you to test it in the comfort of your own home. You can take your time to see how it feels over several months, ensuring it meets your needs before fully committing.

Forever Warranty

The forever warranty means you can trust in the durability and quality of this mattress. It covers you against defects in materials and workmanship, providing peace of mind that your investment is protected for years to come.

What It's Like to Use

When you first unbox the Classic 12 inch King Mattress, it’s exciting to see it expand to its full size. You can expect about 24 hours for it to fully decompress. Once it’s ready, you’ll notice how the foam cradles your body as you lie down, giving that nice “hugging” sensation without feeling trapped.

As you move throughout the night, the mattress responds to your shifts, yet it doesn’t cause any significant motion transfer. If your partner gets up for a glass of water, you might not even notice. The cooling layer does its job well, keeping the surface temperature pleasant even during warmer nights.

Setting up the mattress is straightforward, and it fits perfectly on a standard king size frame. It’s also easy to clean with a removable cover, making maintenance hassle-free.
