No more waking up sweaty in the middle of the night.LAYER 2 – Individually Wrapped Pocket Springs: Hundreds of independent springs respond to your body's unique pressure points – firmer support where you need it, gentle give where you don't. This is what delivers the "medium-firm" feel that sleep experts recommend.LAYER 3 – High-Density Support Foam: The base layer provides durable foundation support, ensuring your mattress maintains its shape and integrity for years.EDGE SUPPORT – Reinforced perimeter prevents sagging when you sit on the edge, giving you the full sleeping surface without the "roll-off" feeling.EASY SETUP – MATTRESS IN A BOXYour mattress arrives compressed, rolled, and sealed in a box small enough to carry yourself. Here's what to do:1. Move the box to your bedroom.2. Open the box and carefully unroll the mattress onto your bed frame or foundation.3. Remove the plastic wrap – the mattress will begin expanding immediately.4. Allow 24-48 hours for full expansion to 12-inch height.5. Enjoy your first night's sleep – the foam will continue to soften slightly over the first week.Q1: Is this mattress good for side sleepers?A: Yes. The memory foam top layer is specifically designed to cushion shoulders and hips – the two pressure points that side sleepers struggle with most. The medium-firm support layer underneath prevents your spine from curving, keeping it naturally aligned throughout the night. Many side sleepers report waking up with less shoulder and hip pain after switching to this mattress.Q2: How long does it take to fully expand after opening?A: The mattress expands to approximately 90% of its full height within 2-4 hours after unrolling. It reaches full 12-inch height within 24-48 hours. We recommend waiting 24 hours before sleeping on it for the best experience. The foam may have a slight "new mattress" smell during the first 48 hours – this is normal and dissipates quickly with ventilation.Q3: Does this mattress contain fiberglass?A: No. This mattress is 100% fiberglass-free. The fire barrier is made using natural materials that meet all federal flammability standards without the use of fiberglass, which is commonly found in lower-quality mattresses. All foams are also CertiPUR-US certified, meaning they are free from formaldehyde, heavy metals, and other harmful chemicals.Q4: What bed frame works with this mattress?A: This mattress works with any sturdy bed frame, including platform beds, box springs, slatted frames (slats no more than 3 inches apart), adjustable bases, and even directly on the floor. The hybrid construction provides enough support that you don't need a specific type of foundation – just make sure the surface is flat and supportive.Q5: Will I feel my partner moving during the night?A: No. The individually wrapped pocket springs move independently – when your partner moves, only the springs directly under them are affected. The springs under your body don't move at all. This is called "motion isolation" and it's one of the biggest advantages of hybrid mattresses over traditional innerspring mattresses.
