Sealy UK Reviews 

Received our mattress 7-8 weeks ago and the smell from the mattress was overpowering, after contacting the retailer we bought it from they went through the usual things like air it well etc but the smell was to much so they visited us to check the smell out and they agreed it was strong ,they went away and rang seals who agreed to replace it . The new mattress was delivered this week and the smell was ok this is excellent service by both sealy and my retailer
Very happy customer

My faith in customer service has been restored!
Very quick response to emails and enquiries and my mattress was amazing! Worth every penny 😴

Needed a firm mattress and this one fitted the bill perfectly.

Always have purchased Sealy beds. Always Loved them.

I purchased another expensive mattress brand to buy local…. Every day I missed my Sealy mattress, the other mattress only 18 months old had to go, it went out the door as my new Sealy mattress came in. In future I will only ever buy Sealy beds. Sleeping much better now thank you.

Excellent service. The delivery men were very professional and helpful. They took care of the surroundings ie wallpaper and carpet and where personal full.

Very well made mattress. I can appreciate it's quality just too firm for me

Being able to track my dilivery and the men doing all the work! Iam more than satisfied with my purchase

I purchased my double Sealy Alston Gel Advantage Pillow Top Mattress on the 3rd Feb 2026. from Amazon uk and it was sold and delivered by Mattressman and labelled Mattressman. It was firmer than I expected, but it was only 25cm high so it may be that pillow top was thinner.
The Sealy specifications are 135cm x 190cm (approx. 4'6" x 6'3") mattress featuring a 29cm depth.
I will probably have to buy a mattress topper to make it more comfortable.

Good service and delivery. Comfortable bed

Our mattress is fantastic

Had to change our mattress after far too many years of use. The Sealy has proved a good replacement; not cheap but well constructed and nicely firm at the edges.

Delivered when said, unwrapped, positioned and took wrapping away.

Problem with mattress quickly resolved. Thanks to all involved.

Excellent product supplied by a first class retailer, St James Beds in Kings Lynn. Delivered on time with exceptional customer service. Sleepless nights a thing of the past.

Best nights sleep in ages, mattress is perfect for me

Comfortable quality bed giving us a great nights sleep.

i have had sealy for years always very good

I was expecting firm mattress but it’s not firm I found it very soft I’m sorry about not giving positive feedback

I find Sealy mattresses to be wonderfully comfortable and having purchased my first one almost 12 years ago when the opportunity arose to replace it I didn't waste any time. We all know that a good night's sleep is essential for one's health and well being and Sealy mattresses definitely contribute to this in spades.

Delivery ready earlier than programmed. Very efficient delivery of new and collection of old mattress
