Are Simba products worth buying?
In short, yes. As a shopping writer who’s tested countless homeware products over the years, I can personally attest that Simba produces some of the highest-quality bedding I’ve ever tried. This year, I’ve upgraded several of my own bedding essentials – and almost all of them are from Simba. Yes, they're expensive. But, I can say with confidence that investing in its sleep products is a surefire way to bring a touch of luxury to your bedtime routine. And Simba outperforms competitors in terms of quality, durability and breathability.
Below, I’ve rounded up the standout picks from Simba’s Cyber Monday 2025 sale – from hybrid mattresses to cooling mattress toppers. These are products I’ve personally tested myself, alongside those tried and approved by the Glamour team, so you can shop with confidence knowing they’re actually worth the investment.

1. Best mattress overall
Why we love it: One of the most sought-after Cyber Monday mattress deals each year is The Simba Hybrid Original Mattress — a long-standing Glamour editor favourite. It combines both spring and foam technology to deliver balanced weight distribution, improved spinal alignment, and pressure relief throughout the night. Plus, it’s a top-rated option that comes with a generous 10-year guarantee.
According to Lian Brooks, Glamour's Senior Audience Development Manager, th Simba Hybrid Original “strikes the perfect balance between support and softness,” offering a firm yet flexible base with excellent cushioning and bounce.
From the very first night, she noticed fewer disturbances from her restless partner – a testament to the Hybrid Original’s pocket spring layer, which expertly minimises motion transfer. As a side sleeper, she found it offered ideal support and cushioning in all the right places, while her partner, who sleeps on their back, experienced better pressure relief and even reported reduced back pain after just a few weeks.

2. Best luxe mattress
Why we love it: This year, one of Simba’s most premium mattresses, the Hybrid Luxe, has had a major price cut for Cyber Monday, with £360 off. Designed to adapt to every body type, it features a wool and bamboo top layer with moisture-wicking properties to help keep night sweats at bay.
The medium-firm mattress strikes a perfect balance of support and softness, boasting an impressive ten-layer construction. Three of these layers are exclusive to the Hybrid Luxe, including carbon steel springs that absorb movement for uninterrupted sleep.
Mayola Fernandes, Glamour's Commerce Writer, says: “I can confidently say the Hybrid Luxe is the most comfortable mattress I’ve ever slept on. It’s supportive, soft, and incredibly breathable. As someone who tends to sleep hot year-round, the cooling features have been a total game changer for the quality of my sleep.”
3. Best 3-in-1 duvet
Why we love it: If a new duvet is at the top of your Cyber Monday wish list, Simba's 3-in-1 version is your best bet for a lightweight, temperature-regulating duvet. The Hybrid 3-in-1 is comprised of two duvets: a spring/autumn 7 tog one, and a cooling 3.5 tog summer one for warmer nights – once clipped together, it becomes the ultimate 10.5 tog winter duvet to snuggle up in for colder nights.
Denise Primbet, Glamour's former Commerce Writer, is a big fan of the duvet's temperature-regulating cotton casing, which effectively wicks away heat to maintain a comfortable sleeping temperature — a feature she found especially helpful as someone who tends to overheat at night regardless of the season. She also appreciates the convenient colour-coding on the duvets, making them easy to differentiate.
“This duvet has made me truly appreciate the value of adjustable layers for different seasons,” says Denise, adding, “it even comes with a handy storage bag, making it easy to tuck away the extra layer under my bed when it’s not needed.” While it’s definitely on the pricier side, the quality and versatility throughout the year make it a worthwhile investment.

4. Best sleep bundle
Why we love it: Simba’s sleep bundle is designed to give you the ultimate in comfort and convenience, offering a carefully curated selection of products to suit your individual needs. You can choose from a range of their highly rated mattresses, including the Hybrid Essential, Original, Pro, Luxe, or Ultra models, each crafted to provide the perfect balance of support and softness. To complete the set, the bundle also includes a Hybrid Pillow and Duvet, ensuring that every aspect of your sleep setup is covered.
Last year, this very bundle proved extremely popular thanks to its exceptional value, with discounts reaching up to 42% off. Customers were able to upgrade multiple bedding staples at once, making it a cost-effective choice for those looking to invest in quality sleep without breaking the bank.
For anyone thinking about a bedding refresh this year, the Simba bundle is the perfect opportunity. With the flexibility to choose the mattress that suits your sleeping style and the added comfort of the pillow and duvet, it’s an all-in-one solution for better rest.
5. Best hybrid duvet
Why we love it: Using Outlast’s fabric technology that was initially designed by NASA for astronauts to regulate body temperature all night long, the Simba Hybrid duvet makes the perfect choice for anyone looking for a trusty all-season option.
Discounted by 20% for Cyber Monday sale, this 10.5 tog duvet is designed for year-round comfort. Its hybrid construction combines active temperature regulation with breathable cotton, keeping you cosy in winter while staying cool on warmer nights. Plus, it’s fully machine washable and tumble-dryer friendly, making it as practical as it is luxurious.
“I personally find it ideal for use from autumn through late spring,” says Mayola Fernandes, Glamour’s Commerce Writer. “For year-round use, the brand’s Hybrid 3-in-1 Duvet might be a better option, as it includes detachable 3.5 tog and 7 tog duvets that combine into a 10.5 tog duvet for colder nights.”

6. Best hybrid pillow
Why we love it: With a temperature-regulating cotton cover, and an adjustable, supportive inner core, you can't go wrong with Simba's Hybrid Pillow. It has in-built airflow channels to keep the pillow breathable all year round, while the supportive inner core make it one of the best pillows for neck pain.
Denise Primbet, Glamour's former Commerce Writer, describes the Simba Firm Hybrid Pillow as an excellent option, particularly for side sleepers like herself. She recommends it for anyone seeking a pillow that balances firmness, customisability, and cooling properties.
“Since switching to this pillow, my neck pain has eased, which is something I've struggled with for years,” says Denise adding “I needed something that keeps my neck aligned without being too firm or too soft". This pillow contours well, holds its shape through the night, and doesn't leave you waking up stiff like so many others on the market.

Why we love it: This body pillow comes with plentiful promises of keeping side sleepers supported during the night, providing hip and spinal support, and aiding the baby bumps of expectant mothers. It's crafted with a nifty, elongated design, featuring a soft curve that sleepers can grip onto and uses heat control technology for an instantly cooling effect.
Neamh Randall, Glamour's Commerce Photo Editor, calls it “one of the best pregnancy pillows I’ve tried,” praising its combination of comfort and support. “It provides full-body support, easing pressure on the back, hips, and shoulders – common trouble spots during pregnancy" she says.
I love its generous length as it allows it to be positioned in multiple ways, whether you prefer hugging it, placing it between your knees, or using it to support your bump. "Even after pregnancy, I still use it as a cosy body pillow, and with a removable, machine-washable cover, it’s easy to keep clean and fresh."
Why we love it: Simba’s Cyber Monday sale last year was also overflowing with discounts on selected top-quality bed frames. This Camden bed frame is our pick, and has the most alluring details, including a cushioned headboard and pressure-relieving slats.
You can customise it to suit your space, choosing from six base designs, including five storage options, and picking from 34 beautiful colours and textures. Made in the UK using FSC-certified wood, it's built to last, backed by a 10-year guarantee and a 200-night trial with free returns.
VIP delivery options are also available, so for an additional fee, Simba’s specialist team can assemble your bed for you, making setup completely hassle-free. Simba also offers a range of ottomans, divans, wooden, and metal beds, and we’ll be keeping a close eye on which ones get discounted this Cyber Monday.
Why we love it: These days, affordable mattresses are often just as high-performing as some of the most expensive mattresses on the market. Simba’s Hybrid Essential Mattress is a seriously smart middle ground in our opinion. It delivers that fresh-bed feel without the premium price tag, and Cyber Monday makes it an even more tempting time to finally retire your tired old mattress.
The Hybrid Essential pairs Simba’s well-loved Aerocoil spring layer with supportive foam to create a balanced, breathable and comfort-focused sleep surface. It’s designed to relieve pressure, reduce motion transfer and keep you cooler throughout the night — all the things your current mattress might be missing.
Why we love it: If a full-on mattress upgrade isn’t in the budget right now, don’t sleep on (literally) the power of a great mattress topper. Simba’s Hybrid Essential Mattress Topper is one of the easiest ways to level up your bed without the faff or expense of replacing the whole thing.
A UK single usually costs £249, but it’s now down to £224.10 — and for that, you’re getting Simba’s signature hybrid comfort in a neat, no-commitment layer. Think: breathable Aerocoil springs for extra support, cushioned foam for instant comfort, and anti-slip technology so it stays put even if you’re a restless sleeper.
It’s ideal if your current mattress is feeling a bit flat, too firm, or just past its prime. Pop this topper on, and you can instantly transform the feel of your bed, boosting both comfort and pressure relief. It’s the kind of quick fix that makes your sleep routine feel upgraded — without blowing the budget.
11. Best Wool Mattress
Why we love it: Eleanor Naylor, Condé Nast’s Affiliate Partnerships Manager, found the Simba Earth Escape Mattress to be a real game-changer after moving in with her boyfriend. In search of a more comfortable solution than her old memory foam mattress, she decided to try Simba’s Earth range, which blends pocketed springs with wool, offering an alternative to traditional memory foam that she had never found comfortable.
From delivery to first use, the experience impressed her. The mattress was brought up to her flat via Simba’s VIP delivery service, and the upgrade from a double to a king-size bed immediately improved space and comfort. Eleanor noted the mattress’s design, including its zoned CoreMax springs and reinforced edges, provided excellent support while reducing motion transfer, meaning she no longer felt her partner moving during the night.
Comfort and materials were standout features. The wool layers offered thermoregulation and moisture-wicking, keeping the mattress breathable, while the sustainably sourced materials and Simba’s B Corp status added reassurance. Sleeping on the Escape mattress consistently left Eleanor feeling refreshed and focused, and despite the higher price point, she felt the long-term benefits made it a worthwhile investment in her wellbeing.

12. Best ottoman storage bed frame
Why we love it: The Didsbury bed frame from Simba makes an instant impression. It comes with a plush, button‑tufted, winged headboard that instantly elevates a bedroom. With a wide selection of fabrics and colours to pick from, it’s easy to customise to your own aesthetic, whether you want something soft and neutral or maximalist and dramatic.
Functionally, one of the biggest draws is the storage‑friendly base. The ottoman‑style storage (or other base options) gives you generous under‑bed space – ideal for storing bedding, extra pillows, or clothes. Reviewers say the gas‑lift mechanism lifts even heavy mattresses easily, and the storage depth is practical for real use.
The only real downside to note – and it’s only a small caveat – is the price. As with many premium upholstered beds, the Didsbury is more of an investment than a budget buy. But, if you're looking for a double, king, or super king size this bed is discounted in Simba's Cyber Monday sale so we wouldn't wait around while stocks last.
Why we love it: This weighted blanket from Simba graced our list of the best weighted blankets for a reason. The Simba Orbit weighted blanket soothes and relaxes with its gentle, comforting weight, thanks to glass nano-beads that help ease restlessness.
Imitating the feeling of a soft, full-body hug, it promotes a calming effect known as deep pressure therapy, encouraging your nervous system to regulate and reduce stress. With its breathable and ultra-soft cotton cover, it also feels gentle against the skin.
It's worth noting that it's available only in a single size, making it better suited as a solo throw blanket for sofa naps if you share a bed with a partner. Additionally, there aren’t multiple weight options, and it’s not suitable for children.
