Best Mattresses for Heavy People (Top 10) – 2026

If you’re shopping for a mattress as a heavier person (often 230 lb+), you’ve probably noticed the same problem: everything claims to be “the best.” The truth is that higher body weight changes what matters most—support, edge stability, durable materials, and a firmness level that keeps your spine aligned.

This guide cuts through the noise with our Top 10 mattresses for heavy people in Canada, all available at National Mattress. We focus on mattresses that offer strong support cores (often pocket coils or high‑density foams), reliable edge support, and comfort layers that won’t bottom out as quickly under higher loads.

Quick tip: If you’re not sure what firmness or construction you need, use the National Mattress Selector and browse our firm mattress and extra‑firm mattress collections for higher‑support options.

Quick take: If you want the best all‑around option, start with Evergreen 14" Euro-top Firm Organic Latex Mattress. It stood out for support/durability, cooling, and edge stability—three areas that matter most for heavier sleepers.

Firmness: 7.5/10  •  Type: Latex  •  Height: 14.0"

Our Testing & Selection Process

What we evaluated

• Mattresses evaluated: Over 200+ mattresses tested from the top legacy brands in Canada including Serta, Beautyrest, Sealy, Stearns & Foster, Tempur-pedic, Kingsdown, Simmons, Chirofoam, Evergreen and more, as well as popular online brands including Casper, Endy, Leesa, Polysleep, Douglas, Logan & Cove, Silk & Snow, Octave, Ghostbed, Juno, Emma, Nectar, Helix and more.
• Key data points per mattress: construction type, coil system (count + gauge when available), edge design, comfort-layer materials, cooling features, warranty terms, and overall value.
• Timeframe: 2025–2026 product cycle (updated for this 2026 list).

How we score mattresses

We score mattresses across multiple categories to reflect what matters for heavier sleepers. Any “test style” metrics and notes are comparative estimates based on materials, construction, and in‑store evaluation.

• Cooling
• Motion isolation / motion transfer
• Responsiveness (ease of moving)
• Response time (how fast the surface rebounds)
• Edge support
• Pressure relief
• Off-gassing
• Sex (bounce + support)
• Brand (track record, warranty policies, and verified owner feedback volume)
• Sleep Trial: 100 Night Sleep Trial at National Mattress

Price is part of the ranking: a mattress can have great performance, but if it’s far more expensive than comparable models, its overall value score drops.

Minimum requirements to make this list

• Available in Canada
• Supportive design suitable for higher body weights (typically firmer comfort + strong core)
• Clear warranty information (most models here are 10 years or more)
• Earned an overall score high enough to rank in our Top 10

The Top 10 Picks (Full Reviews)

Buyer’s Guide: How to Choose the Best Mattress for Heavy People

Heavier sleepers typically do best on mattresses that stay supportive under load, keep the spine aligned, and maintain a stable edge. Here’s what to look for.

1) Pick your firmness based on sleep position

• Side sleepers: often do best around 6.5–7.5/10 (enough cushion for shoulders/hips without sagging). For heavier side sleepers, consider thicker comfort layers like #5 or #8.
• Back sleepers: usually prefer 7.5–8.5/10 for a lifted feel and better lumbar alignment (see #2 and #9).
• Stomach sleepers: often need 8–9/10 to prevent hip sink and back strain (start with #9 or browse extra‑firm mattresses).
• Combo sleepers: prioritize responsiveness so changing positions is easy (latex and hybrids are great—see #1–#3).

2) Cooling: what actually helps

For heavier people, temperature regulation can make or break a mattress. Look for breathable covers, airflow from coils, and cooling foams/latex. Cover fabrics like cooling yarns, Tencel™, and phase‑change style materials can help, but the biggest factor is usually the core: hybrids and innersprings move more air than all‑foam beds.

Certification links worth knowing: CertiPUR‑US® (foam emissions standards), OEKO‑TEX® Standard 100 (textile testing), and GREENGUARD (indoor air quality).

3) Pressure relief vs. ease of movement

Heavier sleepers often need both pressure relief and mobility. Too soft can lead to sagging; too firm can cause pressure points. Latex and responsive hybrids are a common “sweet spot” because they contour without the deep sink of slow memory foam.

4) Couples: motion + edge support

If you share the bed, prioritize motion isolation and edge support. Pocket coils with foam comfort layers are usually the best blend. If you want a couples‑first pick, start at #3.

5) Policies that matter

• Sleep trial: Use the 100‑Night Sleep Trial to make sure the feel works for your body.
• Returns & exchanges: Always review the return policy before ordering.
• Delivery: Check Canada‑wide shipping details (service area, timing, and any remote‑location fees).
• Deals: If price is a priority, shop promos on the mattress sale page and compare value options in our affordable mattress guide.

FAQs

What firmness is best for heavy people?

Most heavier sleepers do best around 7.5–8.5/10—firm enough to prevent sagging, with enough comfort layer to avoid pressure points. Side sleepers may need a touch more cushioning (6.5–7.5/10). If you’re unsure, start with our Top Pick or use the mattress selector.

Are firm mattresses good for back pain?

For many heavier back sleepers, a firm or firm‑hybrid mattress can help by keeping the spine more neutral and reducing hip sink. That said, “best” depends on your sleep position and pressure points. (See our internal note on edge support and firmness.)

How long do mattresses last for heavier sleepers?

It depends on materials and support design, but higher body weight can shorten the lifespan of softer foams. Look for durable comfort layers (latex, higher‑density foams) and strong coil systems, rotate regularly, and use a solid foundation. A 10‑year warranty is common in this category, but real‑world durability varies by use.

Do these mattresses have fiberglass?

Fiberglass concerns are most common in some “mattress‑in‑a‑box” foam models that use fiberglass as a fire barrier. The best way to verify is to check the product page’s materials list and the law label. If you have questions, contact support before purchasing. (You can also browse our FAQ hub.)

Which mattress is best for hot sleepers?

Start with #1 for breathable latex + wool, or #2 if you want a cooling hybrid feel with a firmer surface.

Bottom Line

If you want the safest all‑around choice, get Evergreen 14" Euro-top Firm Organic Latex Mattress for its durable support, cooling materials, and strong edges.

If you’re on a budget, start with Springwall Chiropractic 14" Firm Euro Top Mattress.

If you sleep hot, choose Evergreen 14" Euro-top Firm Organic Latex Mattress (breathable latex + wool + coils).
