Leeward Mattress is a Maine marine-latex specialty brand, sister to Portland Mattress Makers. It makes custom-shaped latex boat mattresses to order. You get a Perfect Fit Guarantee, free shipping, and an 8-year warranty, starting at $1,250. It suits you if you own a boat and need a moisture-resistant custom berth. It isn't for standard bedroom shoppers, since it has no published home sleep trial and no standard-size price grid.

Chapter 02
Comfort and firmness: which mattress fits you
Why this matters to you: Feel names are the brand's words, not measurements. Use them to shortlist two or three beds, then let your body decide.
Choose 6 Inch for bunks and tight clearance or budget custom fits. Choose 8 Inch for all-around adult cabin comfort and support. Choose 10 Inch for maximum plushness where hatch and rail clearance allow.
Choose Luxury Comfort for balanced cushioning or Luxury Plush for extra-soft feel. Side sleepers and pressure-sensitive boaters generally suit thicker latex builds; back and stomach sleepers and low bunks suit thinner builds. Exact ILD firmness and sleeper-position guidance: Not published as of Sept 2026.

Which Leeward Mattress feel fits you?
Weight chart not yet researched
Weight and sleep position can change how a bed feels. We have not yet checked whether Leeward Mattress publishes a fit chart by body weight, so use a trial, where one is offered, to test the bed the way you sleep at home.
Neck: on your side, your nose should line up with the middle of your chest, not tip up or down.
Shoulders: your bottom shoulder should sink in. Tingling or a numb arm means the bed is too firm for you.
Lower back: on your back, slide a flat hand under your waist. A big gap means too firm; no room at all can mean too soft.
Hips: ask someone to look from the side. Hips lower than shoulders means the bed is too soft for you.
Figure 2.1: Four checks to run in a store, lying still in the position you sleep in most. The store test in chapter 11 says how long to lie on each bed.

How well do the mattresses hold up?

Sleep trials, returns, exchanges and fees
Why this matters to you: Feel is hard to judge in a store or in a week. Know your exit plan and its cost before you pay.
No home sleep trial period is listed on the product, guarantee, or warranty pages; assurance is the Perfect Fit Guarantee: if the custom berth shape does not fit, Leeward pledges to remake or replace it, described as no hassles and no questions, remedy by calling the company. Standard return window, refund vs store credit, exchange rules beyond fit remakes, restocking fees, and return shipping costs: Not published as of Sept 2026.
Custom made-to-order status suggests limited standard returns; confirm in writing before ordering.

What do the warranties cover?
Why this matters to you: A warranty is only as good as its terms. Read the written terms and use a supported base, because the wrong frame can end coverage.
8-year warranty covering all workmanship and materials on every boat mattress, per official warranty page; buyers with a manufacturing or material defect are told to contact the company and told Leeward will arrange to replace the product as quickly as possible.
Sagging depth threshold, seam/zipper/cover/vinyl-base coverage, exclusions for commercial charter use or improper bases, proration, proof-of-purchase and law-tag requirements, and step-by-step claim instructions: Not published as of Sept 2026.
Covered when the dip is deeper than Not yet researched, measured with nobody on the bed.
Strip the bed down to the mattress and wait a few hours so the top layers can recover.
Lay a straight edge (a broom handle or long level) across the dip, resting on the flat parts.
Measure from the edge down to the deepest point, then photograph the ruler for your claim.

Leeward Mattress vs. other mattress brands
Why this matters to you: A fair comparison needs the same facts for both beds. Line up price, trial and warranty for each one.
Versus sister Portland Mattress Makers (high-volume innerspring and memory-foam home line with ME/NH/MA shops): Leeward is the marine-latex custom-boat specialist. Versus generic boat-foam or stock-shape marine mattresses: Leeward offers true custom outlines, latex comfort, waterproof base, templating kit, fit remake promise, and 8-year warranty rather than cut foam.
Versus mainstream home DTC latex hybrids: Leeward is not a bedroom substitute with trial-based returns. Head-to-head firmness, cooling, or price testing: Not published as of Sept 2026.
Competitor details reflect published prices and specs on the date shown. Mattress brands may update prices and trial terms over time.
