Review: Buena compra - Este artículo si cumple bien con las especificaciones, muy útil ## Features - Superior Support and Comfort This Sleeping Pad boasts a 4.5-inch thickness and 12-pound foam filling, delivering unparalleled support and comfort. With a weight capacity of up to 440 pounds, this sleeping pad accommodates a variety of body types. Its unique internal structure ensures even distribution of air and foam throughout the pad, effectively reducing pressure points and providing a good night's sleep. Please note that this pad is not recommended for backpacking. - Adjustable Softness This mattress utilizes a unique combination of foam and air, making it fully adjustable for personalized softness and support. This means you can easily adjust the pad's comfort to your liking, allowing for the best sleeping experience. Compared to single-material sponge or memory foam pads, this sleeping pad offers a higher level of personalization and comfort. - Silent and Stable Support for Quality Sleep The mattress provides a stable sleeping surface with minimal noise, ensuring that your movements won't disturb your sleep or your partner's. Unlike other air mattresses that may make annoying squeaking or rubbing sounds, this unique combination of air and foam construction keeps you comfortable and quiet throughout the night. - Easy Inflation and Challenging Deflation The mattress is incredibly easy to inflate, just twist the valve, and you're good to go. However, because of its bulk and weight, deflating the pad may take some patience. To solve this problem, we offer an electric pump, which you can purchase separately. The pump can be used for both inflation and deflation, making the process quick and convenient. Please note that stowing the pad may take some time and effort, but the comfort it provides is worth it. - Four-Season Insulation This sleeping pad boasts an R-value of 13, offering exceptional insulation in cold environments and surpassing many other sleeping pads on the market. The 12-pound foam filling ensures comfort and appropriate insulation in various outdoor environments. Suitable for spring, summer, autumn, and winter, this sleeping pad provides a consistently comfortable sleep experience throughout the year.. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09XLGQ6GR | | Additional Features | Inflatable,Self Inflating Sleeping Pad | | Best Sellers Rank | #79,926 in Sporting Goods ( See Top 100 in Sporting Goods ) #53 in Foam Sleeping Mats for Camping | | Brand | LOSTHORIZON | | Brand Name | LOSTHORIZON | | Capacity | 440 Pounds | | Color | Brown | | Colour | Brown | | Construction Type | Foam | | Cover Material | Air-Resistant Canvas | | Customer Reviews | 4.2 out of 5 stars 460 Reviews | | Fill Material | Foam | | Included Components | Carry Bag | | Item Depth | 11.43 cm | | Item Dimensions | 2.03 x 1.32 x 0.11 Meters | | Item Dimensions L x W x Thickness | 2.03L x 1.32W x 0.11Th Meters | | Item Firmness Description | Adjustable | | Item Thickness | 4.5 Inches | | Item Type Name | Air Mattress | | Item Weight | 16 Pounds | | Manufacturer | Lost Horizon | | Material | Foam | | Material Type | Foam | | Mattress Comfort Layer Material | Polyfoam | | Model Name | LH-DOUBLE | | Model Number | LHCM | | Number of Items | 1 | | Number of Layers | 1 | | Portable | Yes | | Product Benefits | Portable | | Product Care Instructions | Hand Wash Only | | Product dimensions | 2.03L x 1.32W x 0.11Th Meters | | Size | Full | | Special features | Inflatable,Self Inflating Sleeping Pad | | Specific Uses For Product | Sleeping Pad | | Target Audience | Adult | | Water Resistance Level | Water Resistant | | Weight Capacity Maximum | 440 Pounds | ## Product Details - **Brand:** LOSTHORIZON - **Colour:** Brown - **Product dimensions:** 2.03L x 1.32W x 0.11Th Meters - **Size:** Full - **Special features:** Inflatable,Self Inflating Sleeping Pad ## Images ![4.5” Thick Self Inflating Sleeping Pad with Solid Foam, Camping Mattress with Pump Sack, Portable Roll Up Bed, Inflatable Outdoor Mat for Rooftop Tent Car Truck Van, Double - Image 1](https://m.media-amazon.com/images/I/8169+RaVE0L.jpg) ## Questions & Answers **Q: Hi - what's the pad made of - pvc, tpu, other? also, what's the warrantee?** A: Hi, Thank you for your inquiry about the LH AirSoft Mattress.
