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.

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

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.
