Excellent communication and mattress delivery bang on time. Great price on the emma mattress we chose, which is really comfortable
I couldn't quite believe that I could order a mattress on bank holiday weekend and still get next day delivery on a bank holiday, but it really happened. The mattress was the right mattress, it was all in good order, brand new as expected and wrapped in good quality plastic sheeting to protect it and keep it clean which really matters when you're buying a new mattress. The delivery staff will polite, very efficient, they will clearly busy but they didn't mind carrying my mattress up to the first floor, to my front door, which I was thrilled about because of my hernia. All in all I would thoroughly recommend this company and i'm just with almost without words at the efficiency. Not only that, but the slot that I got was early enough for me to still go for a swim with my son on the bank holiday which was fantastic.
Kept me informed about the delivery time which was very helpful. Removed old mattress and put the new mattress on the bed. Very pleasant delivery people.
Couldn't believe they delivered next day on a bank holiday. Delivery guys were fantastic. Offered to take off their shoes, and made sure I was totally happy with goods received. Even took a photo as the box was damaged. On top of it all, the mattress is brilliant! couldn't ask for more.
No issues, 2hr delivery window, seems like a good product, though it's too early to tell if the mattress will sink in the middle.
Fast delivery, great service and swift delivery where I was kept well informed of arrival time. Couldnt fault them!
Easy purchase. Great communications and prompt (very prompt) deliverybeautiful sealy mattress as described
The matress was delivered as promised, on time with with good notice by friendly and helpful couriers. The matress is as described although the 99 transport fee deterred me from returning/exchanging it, even though it is not 100% comfortable for my liking, a peril of online buying. Not a complaint
Great service, next day delivery as arranged and a very comfortable emma mattress. Would highly recommend and will be using this company again in the future.

A proud UK company and a global leader in sleep technology, Simba leads the way. Every mattress combines innovation with environmentally responsible production, and with more five-star reviews than any other mattress brand worldwide, Simba’s reputation for quality and comfort speaks for itself.
Simba uses data from millions of sleepers to develop mattress technology that solves real-world sleep problems. The brand’s engineers have developed Simbatex® foam, a breathable alternative to memory foam that helps regulate temperature, while the Aerocoil® spring system provides precise, responsive support.
Each Simba mattress is designed to adapt to your movements, keeping your spine aligned and reducing pressure points. The result is a refreshing, cooler, and more restorative sleep every night.
Every model is crafted with sustainability in mind, made in zero-waste factories from 100% recyclable materials and certified by multiple environmental organisations.
At MattressNextDay, we’re proud to stock Simba’s most popular models, including:
Simba Hybrid® Luxe Mattress – The ultimate in hybrid comfort, combining plush layers of Simbatex® foam with a triple layer of Aerocoil® springs for enhanced support and cooling.
Simba Hybrid® Pro Mattress – A premium hybrid design with dual layers of Aerocoil® springs and a natural wool top layer for superior temperature regulation.
Simba Hybrid® Original Mattress – Simba’s award-winning all-rounder, offering balanced comfort and affordability with a mix of responsive springs and pressure-relieving foam.

Most of our Simba mattresses arrive rolled and boxed for easy delivery. Simply unbox and unroll, your mattress will expand to its full shape within a few hours, and reach peak comfort after around 72 hours.

Simba mattresses are available in medium or medium-firm feels, offering the ideal balance of comfort and support for most sleepers. Thanks to their hybrid construction, Simba mattresses gently cradle your body while maintaining proper spinal alignment, preventing aches and pressure build-up.
The Simba Hybrid Luxe, for example, combines soft upper layers with supportive Aerocoil® micro-springs that precisely target your body’s pressure points.
