Best Mattress for Heavy People in Ireland (2026)

Reinforced pocket spring and hybrid mattresses built for enhanced support, durability, and edge-to-edge stability — tested for sleepers over 100kg.

Jump to our picks

Finding the right mattress when you carry more weight can be frustrating. Standard mattresses often sag prematurely, lack adequate support, and fail at the edges where you need stability most. Heavier sleepers require reinforced construction, higher-gauge springs, and denser foams to maintain proper spinal alignment and mattress longevity. We've evaluated mattresses available to Irish buyers specifically for support, durability, and edge support — focusing on hybrid and pocket spring options that can handle weights of 100kg+ per person without compromising comfort or developing permanent body impressions.

What to Look for in a Mattress for Heavier Sleepers

Standard mattresses are designed for average weights. Here's what makes the difference when you need more robust support.

Reinforced Support

Look for high-gauge steel springs, reinforced coil systems, or high-density foams (2.0+ lb/ft³). These prevent premature sagging and maintain support year after year.

Hybrid Construction

Pocket spring or hybrid mattresses outperform all-foam options for heavier sleepers. Springs distribute weight more evenly and provide the pushback needed for proper alignment.

Edge Support

Reinforced perimeter frames prevent roll-off and allow you to use the full surface area. Essential for getting in and out of bed and sitting on the edge.

Firmness Level

Medium-firm to firm mattresses (6-8/10) typically work best. Softer mattresses allow heavier bodies to sink too deeply, causing spinal misalignment and discomfort.

The Complete Guide to Mattresses for Heavier Sleepers

Understanding why standard mattresses fail and what construction features make the difference for lasting comfort and support.

Why Standard Mattresses Fail Heavier Sleepers

Most mattresses are engineered for sleepers weighing 60-80kg. When a heavier person uses a standard mattress, problems emerge beyond simple comfort:

Foam Problems

  • • Compresses too easily
  • • Fails to provide pushback
  • • Creates permanent impressions
  • • Loses pressure relief

Spring Problems

  • • Lose tension faster
  • • Middle section sags
  • • Edge springs fail first
  • • Usable surface shrinks

Overall Impact

  • • Poor spinal alignment
  • • Reduced mattress lifespan
  • • Worsening comfort over time
  • • Sleep quality declines

Understanding Mattress Construction for Heavy Use

FeatureStandardHeavy-DutyWhy It Matters
Spring Gauge14-15 gauge12-13 gaugeThicker wire maintains tension under load
Foam Density1.2-1.5 PCF2.0+ PCFResists permanent compression
Zoned SupportOften absentFirmer hips/lumbarDifferent areas get targeted support

Irish Examples: King Koil's Extended Life uses heavy-duty nested pocket springs. Sleepeezee's Ultra Firm 1600 employs thicker wire throughout. King Koil's Chiro-Span and Silentnight's Miracoil both feature zoned support systems.

The Critical Importance of Edge Support

For lighter sleepers, edge support is nice-to-have. For heavier sleepers, it's essential.

✗ Without Edge Support

  • • Balance precariously when sitting
  • • Feel like rolling off when sleeping
  • • Usable surface shrinks over time
  • • Unconscious tension during sleep

✓ Reinforcement Types

  • • Foam-encased perimeters — HD foam wall
  • • Reinforced perimeter coils — stronger edge springs
  • • Full perimeter frames — steel frame support
  • • Best mattresses combine multiple approaches

Sleep Position Considerations

★

Back Sleepers

Best position for heavier individuals

  • • Distributes weight most evenly
  • • Firmness: 7-8/10
  • • Strong lumbar support needed
  • • Try: Respa Extreme Support
★

Side Sleepers

More challenging — pressure points

  • • Weight concentrates on hip/shoulder
  • • Need firm base + cushioning
  • • Adaptive coils help
  • • Try: Sealy Posturepedic Hybrid
★

Stomach Sleepers

Generally discouraged

  • • Midsection sinks excessively
  • • Creates lumbar curve issues
  • • If needed: firmest available (8-10/10)
  • • Try: Sleepeezee Ultra Firm 1600

Temperature Regulation Challenges

Heavier sleepers often sleep warmer due to:

  • • Greater body mass = more heat generation
  • • Deeper sinking = surrounded by heat-retaining foam
  • • Less airflow around the body

Cooling Solutions

  • • Pocket spring/hybrid — air circulates through coil layer
  • • Titanium Aerocoils — act as bellows (Simba Hybrid Pro)
  • • Graphite/gel-infused foam — draws heat away

The Bed Frame Factor

Your mattress is only as good as what it sits on. A weak frame can undermine even the best heavy-duty mattress.

✓ Best Option: Divan Bases

  • • Distribute weight evenly
  • • Designed to pair with specific mattresses
  • • King Koil & Respa recommend matching divans

Slatted Frame Requirements

  • • Slats spaced no more than 7cm apart
  • • Solid wood, not thin plywood
  • • Centre support legs for king/super king

Warranties and What to Look For

The fine print matters more for heavier sleepers who put greater stress on their mattresses:

CheckWhat to Look For
Body Impression Depth25mm or less (avoid 50mm — that's severe sagging)
Weight LimitsCheck if exceeding voids coverage
Prorated vs Non-ProratedNon-prorated = consistent coverage over time

Known Weight Limits:

  • • Simba: Up to 114kg per sleeper
  • • Sleepeezee Ultra Firm 1600: 25 stone individual, 32 stone combined
  • • Others: May have unpublished limits — contact directly

Frequently Asked Questions

Common questions about choosing mattresses for heavier sleepers.

How We Evaluate Mattresses for Heavy Sleepers

Our selection process focuses on the factors that matter most for heavier sleepers — going beyond standard comfort ratings.

Weight Capacity & Support

We verify manufacturer weight ratings and assess how mattresses perform under sustained pressure from heavier loads, looking for proper spinal alignment without excessive sinking.

Edge Support Testing

Critical for heavier sleepers — we evaluate how well the mattress perimeter holds up when sleeping near the edge and when sitting on the side of the bed.

Durability Assessment

We research construction quality, foam densities, spring gauges, and analyse long-term user reviews to predict how mattresses will hold up over years of heavier use.

Irish Availability Verification

Every mattress we recommend is verified for Irish delivery, with accurate pricing in Euro and local retailer information where applicable.
