Custom Dimensions + Irregular Shapes
Need a custom mattress? We specialize in sourcing mattresses of all sizes … even irregular shapes!
For example, here is a Spring Air® mattress crafted for a 1974 Bohler trailer. The customer provided a 1:1 template, and Spring Air® handmade the mattress to exact specifications. The template was returned alongside the customer's new mattress.
If you require a non-standard mattress, please contact us to discuss your specific needs!

The Serta Opalite mattress combines advanced cooling technology with responsive support for a comfortably balanced night’s sleep. CoolFeel™ Fabric and gel-infused foams help regulate temperature, while Talalay latex and GelPlus® memory foam provide uplifting pressure relief and long-lasting comfort. A dual support system featuring micro coils, zoned pocket coils, and enhanced lumbar support delivers excellent spinal alignment, reduced motion transfer, and durable support where your body needs it most.
