Simba’s strongest documented strength is comfortable, supportive hybrid mattresses backed by a long trial and guarantee. It holds a 4.3 TrustScore from 62,313 UK Trustpilot reviews, with 78% five-star. One buyer said “First night’s sleep on it was great,” a pillow buyer said “I love it comes with extra foam for personalising it,” and a one-year owner called Simba’s products “very high quality and comfortable.” Simba is a British sleep company that designs its mattresses in the UK and says it’s a certified B Corp. What sets it apart is its hybrid design, which combines foam with springs, and a 200-night trial with a 10-year guarantee on new mattresses.
The Simba Hybrid (Original) is Simba’s core mattress. Expert Reviews lists it at about £649 for a single, £879 for a double and £999 for a king, while Simba’s own site lists Hybrid mattresses from £549 for a single, and sales of 20% to 25% are common. Simba also sells the Hybrid Pro, which Expert Reviews calls its favourite hybrid mattress, the Hybrid Luxe, the Hybrid Ultra (about £2,999 for a king before sales, per T3), the budget Hybrid Essential, pillows, bed frames and bedding. Expert Reviews says the Hybrid works with all bed bases but sleeps quite warm. Simba offers free delivery and returns and 0% APR finance over 12 months. Refurbished mattresses get a 30-day trial and 1-year guarantee instead.
The honest caveat: a minority of owners report sagging and claim frustrations. One buyer said “Paid a lot of money mattress completely unusable within 3 years,” and another said a £600 bed frame was “Sent with a missing piece.”

We analyzed Simba’s UK Trustpilot profile (62,313 reviews, a 4.3 TrustScore, 78% five-star and 7% one-star, with review invitations, a paid Trustpilot subscription and replies to 95% of negative reviews within a week), plus testing from Expert Reviews, pricing from Tom’s Guide and T3, Ideal Home’s sale coverage, and Simba’s own product pages. GlossGirly has no commercial relationship with Simba that affects this verdict. Sleep-health note: if you develop back pain on a new mattress, give it a few weeks to adjust, use the trial if it doesn’t improve, and see a clinician for persistent pain.
Simba’s range is built around hybrid mattresses. The Hybrid Original combines foam layers with small conical springs, which Expert Reviews says makes it supportive without being hard. The Hybrid Pro adds more springs and a wool layer to stop you overheating, and Expert Reviews called it the most comfortable bed-in-a-box it has tested. The Luxe and Ultra are more premium, while the Essential is thinner and cheaper. Choose based on budget, sleep temperature and preferred feel, and remember Simba frequently discounts its range.
Most buyers love their Simba. Trustpilot reviewers describe improved sleep, strong motion isolation and comfort that lasts. Expert Reviews praises the Hybrid’s balance of comfort and support, though it notes the Original sleeps quite warm. Hot sleepers may prefer the Pro with its wool layer. A minority of owners report sagging or bulging sides after months or years, and one buyer found a mattress worsened their back pain. Use the full trial period to decide.
Delivery is one of Simba’s strengths. Buyers describe next-day delivery, helpful drivers who call ahead, and flexibility to change delivery dates. Mattresses arrive vacuum-packed and expand over time. One buyer said there was no option to recycle their old mattress at the same time, and another found old mattress removal disjointed. Initial off-gassing odour is common with foam mattresses and usually fades within days.
Simba’s 10-year guarantee covers new mattresses, and refurbished mattresses get a 1-year guarantee. Most buyers praise customer service, but some describe frustrating claims, requests for photos and inspections, and bot-heavy email support. One buyer with two refurbished Hybrid Luxe mattresses said both failed within weeks. Other products draw mixed feedback, including a bed frame with missing parts and a duvet cover that wrinkled after washing. Buy new mattresses for the strongest protection.
Simba’s core hybrid mattress, supportive without being hard. It’s best for most sleepers on any bed base. Hot sleepers should consider the Pro.
A premium hybrid with more springs and a wool layer, and Expert Reviews’ favourite hybrid. It’s best for hot sleepers and couples.
An adjustable pillow with removable foam. It’s best for customizing height and firmness. Simba often includes pillows free with mattresses.
Simba’s most luxurious mattress. It’s best for buyers who want top-tier comfort and can wait for a sale.
“After the first wash its gone very wrinkly” — Omri, Trustpilot reviewer (UK, 1 star, 300tc Egyptian cotton duvet cover)
“The mattress is super comfortable.” — Gill, Trustpilot reviewer (UK, 3 stars, Simba mattress)
“Very responsive to changes in delivery date to allow for new carpet!” — Mark Symonds, Trustpilot reviewer (UK, 5 stars, Simba order)
“There is no option to recycle the old mattress at the same time” — David Thornton, Trustpilot reviewer (UK, 5 stars, Simba mattress)
“The top layer has physically sheared and overhangs the base” — Jo Connelly, Trustpilot reviewer (UK, 1 star, Refurbished Simba Hybrid Luxe)
Simba is worth it for most UK shoppers who want a supportive hybrid mattress with a long trial and guarantee. Buy new rather than refurbished for full protection, wait for a sale, choose the Pro if you sleep hot, and use the full trial. If you want a very soft or plush feel, consider other brands.
