Celebrate 100 years of sleep with Sleepeezee! Their new centurial collection embodies the luxurious craftsmanship needed for an undisturbed slumber.

Individualised springs encased in cloth pockets. Expertly adapting to movement to distribute personalised support to each part of your body.

Small, individually cased springs provide added comfort to the mattress whilst offering soothing pressure relief. Mini springs decrease motion transfer so you can share the bed undisturbed.

Stay snuggly all night long. Perfect all year round, wool is a natural insulator and has great temperature regulating properties.

Enjoy the strong moisture-wicking properties of alpaca fibres. The soft, indulgent fillings adjust your body temperature and wicks away moisture so you can enjoy a fresher sleep.

Durable edge-to-edge support provides a maximised sleeping surface for a more secure sleep. Sit and lay comfortably right to the very edge with zero 'roll-off' sensation.

A traditional and elegant design that holds fillings in place whilst enhancing the stability of the mattress. The luxurious tufting ensures zero shifting, shape loss or sagging.
Not too soft, not too firm - the perfect balance

About 10.2 inches deep. Depth is an important factor when buying a mattress as it can affect the suitability for particular bedding, mattress toppers and bed frames.

With a single-sided mattress, there's no need to flip. Simply rotate every few months to care for your mattress. Fuss free mattress maintenance!

Stitched into the mattress border, turning handles are there for easier moving and turning. When caring for your mattress, simply use the handles provided for ease of use.

For the highest standards of quality and safety
Experience a luxurious, undisturbed rest with the Sleepeezee Centurial 01 4500 Pocket Mattress. Sumptuously filled with natural fibres for a cooler night's rest.
100 Years!
Join Sleepeezee in celebrating their centenary! Manufacturing for 100 years, they have built up their reputation of exquisite craftsmanship. Their new Centurial collection embodies the high-quality, traditional craftsmanship Sleepeezee are known for.
Springy support
The base of this mattress features traditional pocket springs. Providing enhanced support by moulding around your unique shape. They move independently from each other, creating an optimal sleeping environment. Perfecting a night of great rest.
Topped with bouncy mini pocket springs. The mattress' design brings you ultimate comfort. The mini springs magnify the cosy comfort by adding an extra bounce to the mattress.
Increased durability
Placing firmer springs along the edge creates a stronger, more durable mattress edge. This provides an increased sleeping area, so you can sleep across the whole mattress. The stronger support allows you to sit on the edge of the bed with ease.
Sumptuous fillings
Lavishly filled with natural fillings, this mattress has plush layers of British wool and alpaca wool. These are inherently cosy so they provide optimal comfort for a deep slumber. The fillings have the benefit of being natural insulators. They help to regulate your body temperature during the night. Keeping you cooler in the summer and warmer in the winter.
Simple care
The Centurial 01 is a single-sided mattress. This mattress only needs rotating, you'll never have to struggle to flip the mattress again! To care for this mattress, simply rotate it top to toe every week for the first three months and monthly thereafter.
Luxurious finishes
The soft, woven viscose cover adds a luxurious finishing touch. The sleeping surface is tufted which creates more stability, holding the fillings together. This design enhances the depth of the mattress, creating a sumptuous sleeping environment.
Traditional quality
Expertly made in the UK, you can trust that this mattress is made to the highest quality. With a 10 Year Guarantee, you can buy with confidence.
This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.

You refer t a small double, firm mattress. What I bought, and have, is a king size, medium. It is rather disappointing. It was very comfortable at first. The wool topping has compacted quickly, leaving hollows. The 'medium' springing is too firm to compress at all under my weight (60kg) so I still have lumbar discomfort.

Good night sleep both happy with the product it was this one or the 103 .

Quite simply it's the most comfortable mattress I have ever slept on. it's have a soft comfort layer on the top but lots of support with the springs. Getting a good sleep, the only problem is getting out of bed in the morning!
