Tell me more about the REM-Fit Hybrid Pocket 1000 Mmattress

The medium-firm REM-Fit Hybrid Pocket 1000 mattress is one of REM-Fit's most pocket-friendly options.

It promises a lower price without compromising on sleep quality, and is made in the UK.

Its hybrid composition offers excellent breathability, pressure relief, and motion isolation, so you'll be undisturbed by a partner's midnight stirs.

The REM-Fit 1000 Memory Foam Hybrid Mattress layers include:

  • The open-cell memory foam comfort layer is soft and more breathable than traditional memory foam
  • 1,000 pocket springs help provide tailored support and keep temperatures cool
  • A high-density eco-foam base foundation ensures stability on any bed base

The thermo-regulating, hypoallergenic, and anti-dust mite knitted cover adds to this cooler and more breathable design.

At 20 cm (7.9 inches) tall, the mattress is thinner than its REM-Fit siblings but still promises exellent comfort.

For the cherry on top, you'll still enjoy the REM-Fit 15-year guarantee, 100-night trial, and free 2-person delivery service with this low-cost model.

Advantages

Most reviews say it strikes the perfect balance between comfort and support

More breathable than traditional memory foam mattresses

Excellent value for money

Free delivery, 100-night trial, and 15-year guarantee

Disadvantages

It is thinner and has fewer pocket springs, thus offering less adaptive support than other REM-Fit mattresses

The REM-Fit mattress selection

REM-Fit, founded in 2014, offers innovative sleep solutions with a 100-night trial, 15-year guarantee, and free 2-person delivery.

The brand features two key collections: Hybrid and Eco mattresses.

REM-Fit hybrid mattresses

REM-Fit’s hybrid mattresses are designed for cool, supportive sleep, blending pocket springs for airflow with memory foam for pressure relief.

Each comes with a thermoregulating, washable, hypoallergenic cover.

The four hybrid options available vary in firmness:

  • REM-Fit 400 Hybrid mattress: 6/10 with a medium feel
  • REM-Fit 500 Ortho Hybrid mattress: 9/10 with a very firm feel
  • REM-Fit 600 Lux Hybrid mattress: 7.5/10 with a medium-firm feel
  • REM-Fit Pocket 1000 Hybrid mattress: 7/10 with a medium-firm feel

Your sleep position helps you choose the best one – stomach sleepers suit the firm 500 Ortho, back sleepers thrive on the medium-firm 600 Lux, and side sleepers would do better on the softer 400 Hybrid.

Sleeping position firmness
Your sleeping position will largely determine the mattress firmness you prefer.

The 500 Ortho, while divisive in REM-Fit 500 Ortho mattress reviews, is ideal for heavier folks or firm mattress fans.

Note: REM-Fit also offers Elite hybrids (like the 600 Lux Elite) for a premium upgrade with extra springs.

REM-Fit Eco mattresses

The Eco range prioritises sustainability with three models:

  • REM-Fit Eco Premium Hybrid: 7/10 with a medium-firm feel
  • REM-Fit Remy+ Eco: 8/10 with a medium-firm feel
  • REM-Fit Remy Kidz Eco: 7/10 and available in a kids’ single size

These use upcycled marine plastic covers and recycled or recyclable foam, perfect for eco-conscious sleepers. 🌍

A quick look at the REM-Fit mattress covers

Most REM-Fit mattress covers are removable, washable, and hypoallergenic, simplifying care - except for the budget REM-Fit Pocket 1000 Memory Foam Hybrid.

  • The hybrid range, including the REM-Fit 400, 500, and 600, features Re-Ax fibre covers that wick away moisture for temperature control.
  • The Eco collection shines with Seaqual covers, knitted from 100% upcycled ocean plastic for sustainability.

We'd still recommend using a mattress protector to boost longevity and guard against spills.

A quick look at the available REM-Fit mattress sizes

REM-Fit offers an impressive array of mattress sizes:

  • REM-Fit small single mattress UK: 75 x 190 cm (2'6" x 6'3")
  • REM-Fit single mattress UK: 90 x 190 cm (3' x 6'3")
  • REM-Fit long single mattress UK: 75 x 200 cm (2'6" x 6'6")
  • REM-Fit small double mattress UK: 120 x 190 cm (4' x 6'3")
  • REM-Fit double mattress UK: 135 x 190 cm (4’6” x 6’3”)
  • REM-Fit king-size mattress UK: 150 x 200 cm (5' x 6'6")
  • REM-Fit super king mattress UK: 180 x 200 cm (6' x 6'6")

As well as these UK-sized mattresses, REM-Fit also has 3 European sizes, including a REM-Fit single, double, and king-size mattress.

While similar, European mattresses are slightly longer and sometimes wider than their UK counterparts.

These are the best-selling REM-Fit mattresses:

Who are REM-Fit mattresses suitable for?

REM-Fit mattresses occupy a mid-range price bracket, frequently made more appealing by REM-Fit discount codes.

Overall, these hybrid designs combine pocket springs and memory foam to cater to diverse sleep preferences.

They're ideal for:

  • Hot sleepers: Breathable open-cell foam and thermoregulating covers ensure comfort. According to REM-Fit 400 mattress reviews, this model really stands out.
  • Couples: Excellent motion isolation, particularly in the REM-Fit Pocket 1000 Hybrid, minimises disturbances from movement.
  • Eco-conscious individuals: Sustainable materials, such as upcycled ocean plastic covers, pair with a 15-year guarantee for durability.
  • Back pain sufferers: The REM-Fit 600 Lux Hybrid provides zoned foam support and most models are well deisgned for back pain relief, though the firmer REM-Fit 500 may not suit everyone.
  • Children: The REM-Fit Remy Kidz Eco delivers an all-foam single mattress with eco-friendly appeal.

But this doesn't mean REM-Fit mattresses are ideal for everyone.

Those preferring a softer mattress may find REM-Fit’s medium-to-firm range less ideal, and buyers seeking either budget options or premium luxury might explore beyond this mid-tier pricing.

We'd recommend turning to the Hypnia Essential Hybrid or the Emma Original Hybrid as excellent budget options, while the Simba Hybrid Pro and the DreamCloud Luxury Hybrid stand out as luxurios choices.

If you're after a fantastic soft mattress that matches feel and luxury, one of the best options is the Simba Hybrid:

How comfortable are REM-Fit mattresses?

Comfort remains a personal experience.

REM-Fit mattresses, however, earn widespread approval, reflected in a 4.3-star Trustpilot rating from numerous REM-Fit mattress reviews.

The REM-Fit 400 Hybrid in particular receives acclaim for delivering a medium-to-firm feel - supportive, yet never overly rigid.

Most models in the REM-Fit range favour this firmer profile, ideal for sleepers who prefer minimal sinkage.

For those seeking a softer touch, options like the Simba Hybrid, Hypnia Supreme Hybrid, or the Tempur mattresses offer a compelling contrast.

What else does REM-Fit offer?

REM-Fit extends beyond its well-known mattresses to include pillows, mattress protectors, and more.

REM-Fit pillows

REM-Fit provides a diverse pillow range to suit various preferences.

Standouts include the popular REM-Fit 500 Cool Gel Pillow, prized for its cooling gel-infused memory foam.

Other options are the REM-Fit 400 Memory Foam Crumbed Pillow, Goose Feather & Down Pillow, Bamboo Charcoal Pillow, and Luxury Travel Pillow.

Each comes with a 5-year guarantee and free next-day delivery. 🙌

Newer cotton and Tencel cool pillow protectors also complement the line-up, matching their mattress protector counterparts.

REM-Fit mattress protectors and toppers

The mattress protector collection features two key options.

  • The REM-Fit cotton mattress protector offers softness, breathability, and hypoallergenic benefits.
  • Alternatively, the REM-Fit tencel cool mattress protector uses durable Tencel fibres to wick away moisture, though some reviews note it feels slippery and less cooling than expected.

A fresh addition, the REM-Fit Halo mattress topper, enhances comfort and support, and we'd highly recommend a mattress topper if you want to add some softness to a firmer mattress.

These extras help prolong mattress life while elevating sleep quality. 😊

What do REM-Fit mattresses cost?

REM-Fit mattresses typically fall within a mid-range price bracket, offering quality without breaking the bank.

The REM-Fit Pocket 1000 Hybrid, starting at around £350 for a single during sales, appeals to budget-conscious buyers seeking hybrid comfort.

In contrast, the premium REM-Fit 600 Lux Hybrid, priced closer to £650 for a single, targets those prioritising extra support and luxury.

Frequent sales and promotions sweeten the deal - discounts often slash prices by up to 50%, and bundles may include free pillows or protectors.

Using a REM-Fit discount code can trim costs further, with offers like 5% or 10% off appearing frequently via the company's newsletter or seasonal deals.

REM-Fit mattress delivery, trial, and guarantee conditions

REM-Fit's free next-day shipping applies across most of the UK, though remote areas like the Scottish Islands miss out.

A no-cost day-of-choice option adds flexibility.

Mattresses arrive compressed and rolled for easy handling, with a premium two-person service - including old mattress disposal - available for a fee. 📦

Some reviews note delayed deliveries, but REM-Fit’s responsive customer support often resolves issues.

The 100-night trial offers a risk-free test period - returns are fully refunded, and collected mattresses are donated to the British Heart Foundation [1], something we can fully get behind.

Offering 100 nights for a trial is an industry standard, but many UK-based brands like Eve, Emma, Nectar, and DreamCloud even offer 200- to 365-day trials.

But, the standout 15-year guarantee outshines many budget brands’ 5-year offers and most bed-in-a-box standard 10-year terms—only premium names like Hypnia and Origin match this longevity.

Check out these other 15-year guarantee mattresses:

Are REM-Fit mattresses any good?

REM-Fit mattresses shine in sustainability and temperature regulation.

Comfort stands out too, with REM-fit mattress reviews frequently praising their supportive feel.

A 15-year guarantee, 100-night trial, and responsive customer support provide solid peace of mind - perfect if concerns arise or the mattress doesn’t quite click.

Overall, it's not hard to see why REM-Fit has such an impressive Trustpilot rating.

  • Who owns REM-Fit?


    REM-Fit is owned by Bell Family Enterprises (BFE).

  • Where are REM-Fit mattresses made?


    REM-Fit crafts its hybrid mattresses in the United Kingdom.

  • What are the REM-Fit certifications?


    REM-Fit mattresses carry trusted certifications that highlight their quality and safety.

    All models use CertiPUR-US certified foam [2], ensuring no harmful chemicals like formaldehyde or heavy metals are used - perfect for health-conscious sleepers.

    The Eco collection features Seaqual fabric, made from upcycled ocean plastic, certified for sustainability and reducing environmental impact.

    These credentials, paired with UK manufacturing, reinforce REM-Fit’s commitment to safe, eco-friendly sleep solutions.

  • Has REM-Fit won any awards?


    REM-Fit’s hybrid mattresses have scooped up notable awards, proving their sleep cred.

    The REM-Fit 400 Hybrid earned a Good Housekeeping Institute nod for its breathable comfort, while the 500 Ortho and 600 Lux Hybrid snagged Which? Best Buy awards for back support and luxury.

    These accolades, backed by REM-Fit mattress reviews, spotlight REM-Fit as a standout in the UK bed-in-a-box scene.

  • What type of bed should you use with a REM-Fit mattress?


    REM-Fit mattresses pair well with platform beds, box springs, or adjustable frames.

    A supportive frame with good airflow - whether slatted or solid - enhances comfort and durability for hybrids like the REM-Fit Pocket 1000 or 500 Ortho, and memory foam options like the Remy+.

    Take a look at our guide on the best bed frames in the UK to help you choose.

  • Do REM-Fit mattresses need to be turned?


    REM-Fit mattresses should NOT be turned or flipped.

    Rotating them every 6 to 12 months, however, prevents uneven wear and sagging.

    This simple step, recommended for models like the REM-Fit 400, 500, 600, Pocket 1000, and Remy+, helps maintain comfort and extend mattress lifespan.

  • Are REM-Fit’s hybrid mattresses better than memory foam mattresses?


    REM-Fit hybrid mattresse pair pocket springs with foam for a balanced sleep experience.

    The springs promote airflow to keep nights cool, while firmer support and motion isolation suit those who overheat or shift often.

    In contrast, REM-Fit memory foam mattresses excel with a softer, body-hugging feel.

    This plush contouring eases pressure points, appealing to sleepers craving sink-in comfort.

    REM-Fit mattress reviews praise both, but hybrids lean cooler and firmer, while memory foam prioritises plush comfort.

  • What's the difference between the REM-Fit 400 and 600?


    The REM-Fit 400 and 600 hybrids cater to different comfort preferences.

    Here’s how they compare:

    • Firmness: The REM-Fit 400 offers a medium feel, slightly softer, while the 600 leans medium-firm for added support.
    • Springs: The 400 has 2000 pocket springs, but the 600 doubles that with 4000 across two layers for enhanced durability.
    • Foam: Both feature breathable open-cell memory foam, though the 600 adds a zoned top layer to target pressure relief.
    • Reviews: REM-Fit 400 Hybrid mattress reviews highlight balanced comfort and back pain relief, while REM-Fit 600 mattress reviews praise instant cosiness and joint support.

    Both excel in airflow and motion isolation, but the 600 suits those seeking firmer luxury.

  • Are REM-Fit mattresses any good for side sleepers?


    Side sleepers typically need medium to soft mattresses that cushion hips and shoulders, such as memory foam or plush hybrids like the Simba Hybrid or Hypnia Supreme.

    REM-Fit mattresses, however, tend to feel firmer, which might not suit those craving a softer sink.

    The REM-Fit 600 Lux Hybrid stands out as a better fit, blending a medium-firm feel with 4,000 pocket springs and zoned memory foam for balanced support.

    Heavier side sleepers could also benefit from the range’s firmness, including the REM-Fit 500 Ortho, for extra stability.

  • What is a REM-Fit Rejuvenated mattress?


    REM-Fit Rejuvenated mattresses are returned beds, steam-cleaned and refurbished for resale.

    Each gets a fresh REM-Fit cover, making them a budget-friendly, eco-conscious choice.

    Not all returns become Rejuvenated - many are donated to the British Heart Foundation for resale in their shops.

  • How does REM-Fit compare to other leading UK brands?


    REM-Fit’s hybrid mattresses stand toe-to-toe with top UK brands, offering a mix of breathability, support, and eco-friendly design.

    REM-Fit versus Emma Sleep

    Emma’s range, like the Emma Hybrid Original, leans into affordable memory foam and hybrid options with a slightly softer feel than REM-Fit’s medium-to-firm hybrids.

    While Emma matches REM-Fit’s free delivery, its 200-night trial outstrips REM-Fit’s 100 nights - though REM-Fit’s 15-year guarantee beats Emma’s 10 years.

    Hot sleepers might prefer REM-Fit’s pocket springs over Emma’s foam-heavy builds, which can trap heat despite cooling upgrades.

    REM-Fit versus Simba Sleep

    Simba’s Hybrid line mirrors REM-Fit with spring-foam combos but often feels softer - and is also pricier.

    Both brands excel in motion isolation, ideal for couples, yet Simba’s 200-night trial and B Corp status [3] edge out REM-Fit’s eco-credentials, while REM-Fit’s longer 15-year guarantee offers greater durability assurance.

    REM-Fit’s UK-made focus and frequent sales give it a value edge over Simba’s premium positioning.
