The Ultimate Guide to Finding the Best Mattress at MattressOnline.co.uk

Yes, MattressOnline.co.uk is a highly reputable retailer with over two decades of industry experience and more than 67,000 positive Trustpilot reviews (maintaining an impressive 4.8/5 average rating). They are authorized dealers for all major mattress brands and have earned the prestigious Online Bed Retailer of the Year award for four consecutive years.

The company provides secure payment processing, transparent pricing policies, and exceptional customer service. Their 60-night comfort guarantee offers additional peace of mind when making your purchase decision.

MattressOnline.co.uk operates primarily as an online retailer, but they do maintain physical showrooms in Rotherham and Skipton where you can experience selected mattress models firsthand. However, their 60-night comfort guarantee effectively allows you to test your chosen mattress in your own home for a significantly longer period than would be possible in a showroom environment.

Research indicates that brief testing in a showroom setting isn’t as effective as sleeping on a mattress for several weeks. The comfort trial provides a more comprehensive opportunity to determine if the mattress truly addresses your specific sleep requirements.

The 60-night comfort guarantee allows you to exchange your mattress if you find it uncomfortable or unsuitable for your personal preferences. This policy is specific to MattressOnline.co.uk and begins from your delivery date.

The manufacturer’s warranty (typically ranging from 5-15 years) covers manufacturing defects and structural issues such as premature sagging or component failure. It doesn’t address comfort preferences or normal wear patterns. The warranty period commences after your comfort trial concludes and continues for the specified duration.

Your ideal firmness level depends on your preferred sleeping position, body weight, and personal comfort preferences:

• Side sleepers typically benefit from softer mattresses (3-5/10 firmness) that cushion pressure points at shoulders and hips
• Back sleepers generally prefer medium to medium-firm mattresses (5-7/10) for proper spinal alignment
• Stomach sleepers often require firmer mattresses (6-8/10) to prevent hip sinking and spinal misalignment
• Heavier individuals (over 90kg) typically need firmer mattresses for adequate support
• Lighter individuals (under 60kg) may find firm mattresses too rigid and prefer softer options

If you’re uncertain, medium firmness (5-6/10) represents the most versatile option that accommodates the majority of sleepers’ needs.

A mattress’s durability depends on its quality, construction materials, and maintenance practices:

• Entry-level mattresses (£200-£500): 3-5 years
• Mid-range mattresses (£500-£1,000): 5-7 years
• Premium mattresses (£1,000+): 7-10+ years

To maximize your mattress’s lifespan, use a quality mattress protector, rotate it regularly (if recommended by the manufacturer), and ensure it has proper support from your bed base. Indicators that it’s time to replace your mattress include visible sagging, noticeable indentations, increased allergy symptoms, and waking with persistent aches and pains.

For back pain relief, we recommend the Origin Hybrid Pro or the Simba Hybrid Pro. Both offer exceptional support with zoned pocket spring systems that provide targeted firmness in the lumbar region while maintaining overall comfort.

The Origin Hybrid Pro features a seven-zone support system specifically engineered to address back issues, while the Simba Hybrid Pro combines up to 5,000 responsive springs with pressure-relieving foam layers to maintain proper spinal alignment.

Medium-firm to firm mattresses (6-8/10 firmness) are generally recommended for back pain sufferers, though individual needs may vary. The 60-night comfort guarantee allows you to ensure your selection effectively addresses your specific back concerns.

Proper maintenance extends your mattress’s lifespan and preserves its comfort and support qualities:

• Use a mattress protector: Always use a waterproof, breathable mattress protector to guard against spills, stains, and allergens
• Regular rotation: Rotate your mattress 180 degrees every 3-6 months (unless manufacturer guidelines specify otherwise)
• Vacuum periodically: Use your vacuum’s upholstery attachment to remove dust and allergens from the mattress surface
• Address spills immediately: Blot (don’t rub) any spills with a clean, absorbent cloth
• Air occasionally: When changing bedding, allow your mattress to air for a few hours before remaking the bed
• Proper support: Ensure your bed base provides adequate, even support for your mattress type

For mattresses with removable, washable covers (like many Emma and Simba models), follow the manufacturer’s specific washing instructions carefully.

Not necessarily, but your existing bed frame should meet certain criteria to properly support your new mattress:

• Appropriate size: The frame dimensions must match your mattress size exactly
• Adequate support: Slat spacing should be no more than 7cm apart for foam mattresses
• Structural integrity: The frame should be sturdy without squeaks, cracks, or excessive movement
• Compatibility: Some mattress warranties require specific base types (check manufacturer guidelines)

If your current frame is old, damaged, or doesn’t provide proper support, investing in a new bed frame alongside your mattress is advisable. MattressOnline.co.uk offers compatible frames for all their mattresses, often with bundle discounts when purchased together.

MattressOnline.co.uk offers a straightforward price match promise to ensure you get the best possible value. If you find an identical mattress at a lower price from another authorized UK retailer (including delivery costs), they’ll match that price. To request a price match:

1. Contact their customer service team before placing your order
2. Provide details of the competitor’s offer (website link or screenshot)
3. Ensure the competitor’s product is identical (same size, model, and specifications)
4. Confirm the competitor has the item in stock for immediate delivery

This guarantee applies to advertised prices only and excludes clearance items, display models, and special promotional bundles. The team typically responds to price match requests within 24 hours.

Selecting the appropriate mattress size depends on your room dimensions, sleeping arrangements, and personal space preferences:

• Single (90cm x 190cm): Suitable for children, teenagers, or adults with limited space
• Small Double (120cm x 190cm): Good for single adults who want extra space or couples with very limited room
• Double (135cm x 190cm): Standard choice for couples, provides each person with approximately 68cm of personal space
• King (150cm x 200cm): Offers more width and length, ideal for couples who value personal space
• Super King (180cm x 200cm): Maximum space for couples, particularly beneficial for restless sleepers

For optimal comfort, ensure at least 60cm of clear space around three sides of the bed for easy movement. Your mattress should be at least 10-15cm longer than the tallest sleeper to prevent discomfort.

MattressOnline.co.uk offers a convenient and environmentally responsible solution for old mattress disposal. For £35, they’ll collect your old mattress when delivering your new one and ensure it’s properly recycled rather than sent to landfill.

This service helps reduce the environmental impact of the approximately 7 million mattresses discarded annually in the UK. Their recycling partners dismantle mattresses to separate and recycle components including:

• Metal springs and components (recycled into new metal products)
• Foam and padding (repurposed for carpet underlay or insulation)
• Fabric and textiles (recycled into industrial cloths or fiber products)
• Wood (from divans, repurposed or used for biomass energy)

Simply add the recycling service to your order during checkout, and the delivery team will handle everything on delivery day.

Memory foam and hybrid mattresses offer distinctly different sleep experiences:

Memory Foam Mattresses:

• Constructed entirely from various foam layers (memory foam, polyfoam, etc.)
• Exceptional pressure relief and body contouring
• Superior motion isolation for undisturbed partner sleep
• Silent with no spring noise
• May retain heat unless designed with cooling technology
• Provides a “hugging” sensation that some sleepers love and others find restrictive

Hybrid Mattresses:

• Combine pocket springs with foam comfort layers
• More responsive and bouncy than all-foam options
• Better airflow and cooling properties
• Enhanced edge support for full mattress utilization
• Balance of pressure relief and support
• Generally more suitable for heavier individuals

Hybrids aim to offer the best of both worlds—the support and breathability of springs with the comfort and pressure relief of foam. They’re particularly popular with sleepers who find all-foam mattresses too enveloping or warm.

Vacuum-packed mattresses (particularly memory foam and hybrid models) require time to expand to their full size and comfort level after unboxing:

• Initial expansion: Most mattresses reach 90% of their full size within 4-6 hours
• Complete expansion: Full height and firmness typically develop within 24-48 hours
• Comfort development: Some premium models may continue to soften slightly over the first 30 days

Factors affecting expansion time include room temperature (warmer rooms speed up the process), mattress thickness (thicker mattresses take longer), and mattress type (all-foam models generally expand faster than hybrids).

You can sleep on your mattress immediately after unboxing, though the comfort experience may improve slightly as it reaches full expansion. Any initial “new mattress smell” typically dissipates within a few days with good ventilation.

Couples have several important factors to consider when selecting a shared mattress:

• Motion isolation: Critical if one partner is a restless sleeper or has a different schedule; memory foam and high-quality hybrids excel here
• Edge support: Important for couples who utilize the full mattress surface; look for reinforced perimeters
• Temperature regulation: If one partner sleeps hot, prioritize cooling technologies like gel-infused foam or breathable covers
• Firmness compromise: If preferences differ significantly, consider medium firmness or dual-tension options
• Size considerations: King or super king sizes provide each person with more personal space (75-90cm per person)
• Weight distribution: If there’s a significant weight difference between partners, look for responsive mattresses that adapt to different body types

The Simba Hybrid Pro and Emma Original Hybrid both score exceptionally well for couples due to their excellent motion isolation, edge support, and balanced medium firmness that accommodates different preferences.
