It is extremely comfortable, well insulated, and surprisingly doesn’t sleep hot like some foam mattresses can. We woke up feeling like we had slept on a real bed rather than an air mattress. The biggest difference is the foam filling. It provides much better support and doesn’t have that “bouncy” feeling you get with a traditional inflatable mattress. The rechargeable pump is another huge plus. It inflates the mattress quickly and makes deflating it just as easy when it’s time to pack up. No struggling with a manual pump or trying to squeeze all the air out by hand. We use it in the back of our SUV, and it fits our setup perfectly. After sleeping on this, we will never go back to a traditional inflatable air mattress for camping. It’s comfortable, supportive, insulated, and incredibly convenient. If you’re looking for a comfortable car-camping mattress, I highly recommend this one. It’s worth every penny! Review: Affordable and comfortable - I initially wanted to purchase an Exped, but the price point was too high. This was at half the price plus you get a thicker mattress. My wife and I preferred using it with the least air and practically all foam, with both of us on the mattress the little air inside compressed enough to allow enough firmness for support and the foam gave enough cushion for a good night's sleep. It took 3 nights of camping to figure this out, but we know what we like on our next trip. It's easy to setup. Unpack and open the vent to allow it to self-inflate which takes less than 5 minutes, then adjust the air to your liking. High quality for sure!!! ## Features - 【Superior Support and Comfort】This Sleeping Pad boasts a 4.5-inch thickness and 13-pound foam filling, delivering unparalleled support and comfort.

Insanely comfortable - I might as well be sleeping on my mattress at home. Size is accurate to listing, and it is fairly big when packed up, but absolutely worth the space. I do highly recommend the pump option - makes it very easy to set up and put away. Very easy to roll up and put into the stuff sack it comes with. ## Frequently Bought Together - LOSTHORIZON Air & Foam Camping Mattress, Self-Inflating Sleeping Pad, 4.5" Thick, with Air Pump, Queen - Arcturus Military Wool Blanket - Warm, Thick, Washable - Great for Outdoors, Camping, Stadium Blanket, Picnics, Travel - Car & Bushcraft Survival Kits, Large 64in x 88in 4.5 lb - Amazon Basics Waterproof Camping Tarp, 10 Feet x 12 Feet, Dark Green --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/659122349-lost-horizon-option3-self-inflating-foam-camping-mattress-queen-4](https://www.desertcart.tn/products/659122349-lost-horizon-option3-self-inflating-foam-camping-mattress-queen-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-19*
