Ruoysun King Size Mattress, 14 Inch Medium Firm Hybrid King Mattress in a Box, Strong Edge Support, Motion Isolation, with 7-Zones Pocket Springs, Fiberglass-Free, Pressure Relief, CertiPUR-US

Features

• Luxurious Comfort & Ergonomically Designed: Our exclusive Ruoysun 7-Zone Pocket Spring System is precision-engineered to match your body's natural curves. As you lie down, shoulders sink slightly for pressure relief, the lumbar spine receives targeted lift, and legs rest easy. A plush memory foam layer adds just enough softness on top, delivering a medium firm feel that's truly "just right" for your king size memory foam mattress whether you sleep on your back, side, or stomach.
• Silent Motion Isolation: Over 600 individually pocket springs mean motion stays where it starts. If you're sharing your king bed mattress with your partner or pet, the motion is absorbed right where it starts. You won't feel a thing. No noise, no vibration. Light sleepers, this is your peace of mind.
• Edge Support You Can Count On: We added 3 rows of reinforced springs around the perimeter, delivering 30% more reinforcement for lasting durability. Sit, sleep, or lounge near the edge with complete confidence, and the surface stays solid and supportive, edge to edge. The whole medium firm king mattress stays solid.
• Say Goodbye to Hot, Stuffy Nights: Our 7-layer construction in this king size mattress medium firm includes a cooling-gel memory foam layer and ventilated comfort foams that actively wick away heat and moisture. Paired with a soft, breathable knit cover, you stay cool, dry, and comfortable with no more night sweats.
• King Mattress in a Box: We roll and compress each Ruoysun into a box so compact, it glides through doorways and up stairs with ease. Just unbox, unroll and expand (allow 4872 hours for full shape). Every Ruoysun is built with multi-stage quality inspections, CertiPUR-US certified materials, and fiberglass-free construction. Backed by a 10-year limited warranty.

Designed with motion isolation to minimize sleep disruptions, absorbing noise and vibrations so your partner can rest peacefully. Visit the Store Visit the Store My partner and I have different sleep schedules. If one of us gets up or tosses at night, will it wake the other up? That’s a key benefit of hybrid mattresses. Each pocket spring works independently, conforming to your body and absorbing most motion, which helps reduce disturbance. I’m a side/stomach/back sleeper. Is this mattress suitable for me? Hybrid mattresses are designed to work well for different sleep positions. We recommend a medium-firm model (firmness level 5–7.5) which suits most sleep positions and body weights. I sleep hot. Will this mattress trap heat and make me sweat? The pocket spring structure of a hybrid mattress offers good breathability. Gaps between springs create natural air channels for heat and moisture dissipation. Is the mattress made of safe materials? Will it have a strong chemical smell? It's made with safe materials. You may notice a faint material smell upon unboxing, which typically dissipates significantly within a few hours in a ventilated area. I’m confused between Pillow Top and Euro Top. Which one is right for me? It really comes down to comfort and how you plan to use the mattress. Our EURO TOP is for you if: You want a balanced sleep—soft and supportive without that “stuck-in” feeling. It offers a more durable, luxurious feel, similar to high-end hotel beds. 14 Inch King Mattress 12 Inch King Mattress 14 Inch Queen Mattress 12 Inch King Mattress 14 Inch Queen Mattress 10 Inch Full Mattress 12 Inch Cal King Mattress
