Not every sleep space is standard, and neither should your mattress be. Haven now offers custom sizes for our most popular collections: the Hiber Firm, Hiber Medium-Firm, Hiber Medium-Plush and Rejuvenate Plush mattresses. Whether you need the perfect fit for a boat, RV, cottage loft, antique bedframe, or a uniquely designed space, we’ll craft a mattress tailored exactly to your dimensions.

Why Choose a Haven Custom Mattress?

• Canadian-Made Quality – Every custom mattress is handcrafted in Canada with the same premium, eco-friendly materials trusted in our standard collections.

• Tailored Comfort – Choose from our carefully engineered models to match your preferred firmness, support, and sleep style.

• Perfect Fit Guarantee – We build to your measurements, so your mattress fits your space without compromise.

• Healthy, Restful Sleep – All custom mattresses feature Haven’s CertiPUR-US® certified foams, plant-based materials, and luxury comfort layers.
