Slumber Castle – Sleep Like Royalty

We spend nearly half our lives in bed, and at Slumber Castle, we believe that quality sleep is the foundation of a better, healthier life. Our mission is to create a sleep environment that’s not only comfortable, but also supportive, safe, and restorative. From premium materials to thoughtful design, every Slumber Castle mattress is crafted to elevate your sleep experience.

This Slumber Castle hybrid mattress is made with top-quality materials that are CertiPUR-US and OEKO-TEX STANDARD 100 certified—meaning they’re breathable, safe, and free from harmful substances.

Our mattress features zoned ergonomic support that adapts to your body and relieves pressure on your shoulders, back, and hips. Individually wrapped coils promote natural spine alignment and minimize motion transfer, so you can sleep undisturbed—even if your partner tosses and turns.

The mattress comes zipped and compressed in a compact box, making it easy to carry and ideal for your first apartment, guest room, or any space where convenience matters. Just unbox, unroll, and watch it expand.

1. Safety Notice: Slumber Castle mattresses arrive in a compact but heavy box. Please use two people when lifting or moving it upstairs. Use the included cutting tool carefully and keep a safe distance—the mattress expands rapidly once unwrapped. Allow 24–72 hours for full expansion.

If you’re new to boxed mattresses, we recommend watching the full unboxing video in the “Main Product Video” or “A+ Video” section for step-by-step guidance.

2. Edge Sitting Tip: For better support when sitting on the edge, sit slightly inward—this provides more stability for your hips and legs.

3. Comfort Takes Time: Firmness is subjective. Some people may find the mattress soft, others firm. Allow a few nights for your body to fully adjust to the medium-firm support.
