LOSTHORIZON Air and Foam Camping Mattress Self-Inflating Pad 4.5 Inch Thick

Sleep Comfort That Travels with You

Introducing the LOSTHORIZON Air and Foam Camping Mattress—a sleeping pad designed for car campers, weekend explorers, and anyone who wants a solid rest after a day outdoors. With a 4.5-inch thickness and a 5.5-pound foam core, it delivers a cushioned, supportive surface that blends the buoyancy of air with the dependable feel of foam. It supports sleepers up to 220 pounds and aims to keep a balanced surface throughout the night. Note: this pad is not recommended for backpacking due to its size and setup needs.

Hybrid Comfort: foam and air working in harmony

The secret is the blend. An internal structure spreads air and foam evenly, helping to reduce pressure points and keep your spine aligned on uneven ground. The system is fully adjustable, so you can fine-tune softness without sacrificing underlying support. For longer trips or changing conditions, you can dial in a lighter or firmer feel while enjoying the foam’s stable foundation.

• Adjustable softness: tailor the feel by changing air levels while the foam core maintains a steady base.
• Silent, stable surface: designed to minimize noise and movement for restful sleep.
• Easy inflation and quick deflation: twist the valve and use the pump sack to speed setup; deflates in about 40 seconds.

All-Season comfort you can rely on

Insulation plays a key role in comfort. With four-season insulation and an R-value of 13, the pad helps maintain warmth across spring, summer, autumn, and winter camps. The 5.5-pound foam filling adds a cushioned feel that remains durable through repeated use, helping to smooth out rough ground and rocky patches beneath.

• R-value 13 insulation supports warmth in diverse environments.
• High weight limit up to 220 pounds for broader comfort options.
• Durable construction promotes long-term use across multiple trips.

Practical design, easy care, practical setups

Designed with real-world camping in mind, this mattress is straightforward to set up in a tent, a vehicle campsite, or a backyard sleepover. The combination of air and foam offers a balance that many campers seek: a surface that feels solid under pressure, yet soft enough to cushion joints after a day outdoors. For storage, the compact profile helps you pack alongside other gear, and the pump sack keeps the inflation tool handy for next time.

• Four-season readiness plus a simple, reliable setup workflow.
• Not backpacking-friendly due to size and weight considerations.
• Care: keep dry, wipe clean after use, and store in a cool, dry place.

Whether you’re car camping for a weekend, setting up at a festival, or hosting a backyard campout, the LOSTHORIZON mattress offers a versatile sleep solution that emphasizes a balanced, quiet, and supported rest without overpromising outcomes.
