Twin mattress in a box 12 inch Independent pocket springs strengthen edge support, operate individually without interference, and compress and rebound smoothly. Low friction, minimal noise, conform to the spine's curve, offering stable support and a smooth, comfortable feel.
Imported Fabric + Boxed Design + Flame Retardant Certification – A Mattress Built for Cross-Border Sellers
Every layer of this mattress, from the surface to the internal structure, has been carefully selected. The top quilted composite layer combines polyester foam, thin wave foam, and high-quality knitted fabric.
The knitted fabric is imported from Germany and offers two key features: first, it is environmentally friendly – produced without banned chemicals and easier to degrade after disposal; second, it is highly breathable. Together with the wave foam's air channel design, moisture and heat released by the body during sleep are quickly expelled, reducing that sticky, clammy feeling.

Health Protection Features. The fabric is treated for dust resistance, anti-dust-mite, and anti-static properties. For families with allergy-prone members, or for high-turnover settings such as rental properties and homestays, this protective layer effectively reduces skin discomfort caused by dust mites or static electricity.

All materials meet green environmental standards – odor-free, containing no heavy metals or harmful plasticizers.Support System Breakdown. Beneath the foam layers, we have added high-resilience foam. Unlike ordinary sponge, which rebounds slowly after compression, high-resilience foam quickly returns to its original shape after the body moves away, resisting body impressions even after long-term use.
In addition
The support it provides falls into the "firm yet cushioned" category – enough surface hugging for comfort, while the deeper layers hold the body up, preventing the lower back from hovering without support. For space-constrained RVs or compact bedrooms, the short queen mattress in a box delivers the same support system in a more space-efficient size. For those prioritizing back support, the queen firm mattress in a box offers enhanced lumbar firmness. And for users who prefer a softer sleep surface, the soft queen mattress in a box provides a plush, cloud-like feel without compromising the underlying support.
Optimized for E-Commerce and Cross-Border Logistics. twin mattress in a box 12 inch uses a boxed roll-compressed design – compressed and sealed into a standard-sized carton after production. Compared to traditional flat-pack mattresses, the shipping volume per unit is reduced by approximately 70%, significantly lowering sea freight costs, overseas warehouse storage fees, and last-mile delivery expenses. At the same time, this mattress has passed flame retardant standards tests for both the US and the UK, meeting compliance requirements for platforms such as Amazon.
We accept OEM and full-process customization. Fabric patterns, firmness levels, spring specifications, carton printing – you name the requirements. Minimum order quantity is flexible. Please send your inquiry for detailed specifications and sample policy.
