After being let down by another company (my mattress getting lost in transit). I was dubious about getting another mattress ordered however my delivery was on time and delivery updates were accurate. The two delivery chaps were efficient and polite and the old mattress taken away. Very pleased with the service and product.
Easy to navigate the website arrived in the time stated brought it straight in and removed the old on within minutes highly recommend
Other suppliers were quoting long lead times. Ordered and the mattress we wanted was delivered the next at the specified time and our old one taken away. Very pleased.
The ottoman bed and serenity mattress was deliveredon time and the delivery was very quick and efficient.So much storage in the ottoman base, wish I had got one years earlier.
Bought a replacement for our tired hypnos, from looking at all the various ranges available, and choosing our replacement the process, delivery and quality of the product was faultless - thank you!
My daughter had purchased this mattress so I didn't have to do much research, I was able to check her mattress in the first instance. The mattress itself has a 10 year warranty and is which recommended. It was in the sale at the time and with a little research through money back options and my blue light card I had a little extra discount so this made it value for money also. The mattress is excellent quality and I feel very supported. I am able to sleep on my front without pain now which is great. There are two things I would like to make others aware of which I overlooked. Firstly, there is an extra charge for the mattress to be taken upstairs. I didn't notice this, initially I wasn't bothered as in my younger days I worked in a hotel and moving mattresses was standard - please pay to have your mattress taken upstairs. The mattress is 45kg and I couldn't move it by myself at all. The second thing. The mattress is very well wrapped, twice. The inner wrapping is thick plastic and vacuum packed, the outer wrapping is like a extra strong cling film. I have seen the comedy sketches where mattresses open and surprise people. I assumed it would be the inner layer which would spring the mattress open. It isn't! the outer cling film layer once you release it opens the mattress fully. I live alone, and it opened quickly and upside down, turning this over was a challenge so please be careful. The mattress is deep and feels luxurious. I had to order all new mattress protectors and sheets which is a lovely extra treat. My bed is now super high too. Great for me - I feel like a queen. But it makes it hard for my dog who now struggles to get on the bed ( and shes a big dog!), something else to bear in mind. I definitely recommend this mattress.
Despite a late order was delivered on time by helpful crew. Choice of mattresses was vast with detailed measurements of each mattress in all sizes

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 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.
