This mattress is one of the best for frequent use, maintaining firmness without frequent reinflation.

The Serta Raised Air Mattress with Never Flat Pump is a Queen-sized, 18-inch luxury inflatable mattress designed for both convenience and comfort. One of its standout features is the Never Flat Technology, which employs two pumps: one for rapid inflation and deflation, and a secondary silent pump that maintains your desired firmness throughout the night. This is particularly beneficial for those who value consistent support and minimal disruptions during sleep.

The mattress is constructed from heavy-duty, waterproof, and puncture-resistant materials, contributing to its durability and making it suitable for various settings like camping, sleepovers, or hosting guests. The 18-inch height makes getting in and out of bed easier, which is an added convenience for adults and elderly users. Additionally, the mattress includes 35 independent coils that offer a firm yet supportive sleeping surface, with a plush flocked top that enhances comfort and helps secure bed sheets in place. Motion isolation is well-addressed by the independent coil system, making it a good option for couples.

However, it's worth noting that, as an air mattress, it might not provide the same level of temperature regulation as traditional foam or hybrid mattresses, potentially leading to a warmer sleep experience. The edge support is decent but may not be as robust as that of a traditional mattress, so those who frequently sit on the edge might find it less supportive. The product comes with a two-year warranty, reflecting confidence in its durability. This air mattress is ideal for adults looking for a portable, comfortable, and easy-to-use temporary sleep solution. Its built-in pump and storage features make it particularly user-friendly, but it may not be the best choice for those prioritizing advanced temperature regulation and edge support.

Rating
7.6
Durability

Most important from
470 reviews

Durability
Holds air well and is very durable.

The iDOO Luxury Air Mattress stands out with its built-in pump, making inflation quick and hassle-free within 2-3 minutes. This feature is convenient for both camping trips and accommodating guests. The mattress is made from eco-friendly PVC that is 15% thicker than ordinary materials, ensuring extra durability and water resistance.

The firmness level is described as firm, which might appeal to those who prefer solid support while sleeping. The included non-slip strip on the bottom adds stability, reducing noise and motion transfer, which enhances sleep quality. The product also comes with a storage bag, making it portable and easy to carry.

At 19.06 pounds, the mattress is relatively lightweight, benefiting portability. However, the continuous coil design may not provide the same level of support as traditional sprung mattresses. It could be especially suitable for casual use such as camping or occasional guest accommodation, but might not be ideal for permanent, everyday use due to potential concerns about edge support and long-term durability.

Buying Guide for the Best 18-Inch Mattresses

Choosing the right mattress is crucial for a good night's sleep and overall health. When selecting an 18-inch mattress, it's important to consider various factors that will affect your comfort, support, and durability. Understanding these key specifications will help you make an informed decision that best suits your needs and preferences.
MaterialThe material of a mattress determines its comfort, support, and durability. Common materials include memory foam, latex, innerspring, and hybrid. Memory foam offers excellent contouring and pressure relief, making it ideal for those with joint pain. Latex is known for its durability and natural resistance to allergens. Innerspring mattresses provide good support and are often more breathable, while hybrid mattresses combine the benefits of multiple materials. Choose a material based on your comfort preferences and any specific health needs.
Firmness LevelFirmness level refers to how soft or hard a mattress feels. It is important because it affects your spinal alignment and overall comfort. Firmness is usually rated on a scale from 1 to 10, with 1 being very soft and 10 being very firm. Soft mattresses (1-3) are suitable for side sleepers who need cushioning for their shoulders and hips. Medium mattresses (4-6) are versatile and work well for combination sleepers. Firm mattresses (7-10) provide more support and are ideal for back and stomach sleepers. Consider your sleeping position and personal comfort preference when choosing the firmness level.
SupportSupport refers to how well a mattress maintains your body in a neutral position, keeping your spine aligned. Good support is essential for preventing back pain and ensuring restful sleep. Mattresses with high-quality support systems, such as pocketed coils or high-density foam, provide better support. If you have specific support needs, such as for back pain, look for mattresses that offer targeted support zones or reinforced edges.
Motion IsolationMotion isolation is the mattress's ability to absorb movement and prevent it from transferring across the bed. This is important for couples, as it minimizes disturbances when one person moves or gets up. Memory foam and latex mattresses typically offer excellent motion isolation, while innerspring mattresses may transfer more motion. If you share your bed with a partner, consider a mattress with good motion isolation to ensure uninterrupted sleep.
Temperature RegulationTemperature regulation refers to how well a mattress can maintain a comfortable sleeping temperature. This is important for preventing overheating during the night. Materials like gel-infused memory foam, latex, and innerspring systems with breathable designs can help with temperature regulation. If you tend to sleep hot, look for a mattress with cooling features to ensure a comfortable sleep environment.
Edge SupportEdge support is the strength of the mattress's edges and its ability to hold weight without sagging. This is important for those who sit on the edge of the bed or need the full surface area for sleeping. Mattresses with reinforced edges or higher-density foam around the perimeter offer better edge support. If you frequently use the edge of your bed, consider a mattress with strong edge support to prevent sagging and increase durability.
DurabilityDurability refers to how long a mattress will maintain its comfort and support over time. This is important for ensuring a good return on your investment. High-quality materials and construction methods contribute to a mattress's durability. Look for mattresses with good warranties and positive customer reviews regarding longevity. If you want a mattress that will last for many years, prioritize durability in your selection.
