Not every sleep space is standard, and neither should your mattress be. Haven now offers custom sizes for our most popular collections: the Hiber 6, Hiber 8, and Rejuvenate 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.

Available Models

• Hiber 6: Lightweight and versatile—ideal for tight spaces and wallbeds.

• Hiber 8: Slim profile with supportive comfort—perfect for kids, guest rooms, and multi-use spaces.

• Rejuvenate: Our flagship natural Talalay latex mattress—premium pressure relief and cooling for restorative sleep.

• Free Shipping coast to coast in Canada and the contiguous United States. Territories and remote areas may have a surcharge per item based on weight and size of the product.
• Made to order generally in 3-5 business days
• FedEx delivery normally takes 1-4 business days depending on location.
• All Haven mattresses (except custom sizes) feature a 100-night comfort sleep trial.
• To reduce waste we only offer 1 mattress return per household. We encourage you to buy 1 to try before ordering multiples for this reason.
