Thank you for your review
It was firmer than I expected.
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.

Thank you for your review.
The depth is measured at the loft of the mattress which is the very deepest point. Measuring the side of the mattress will give a different reading.
We're sorry you're finding it a little too firm and hope a topper helps to provide the additional luxury required.
Best wishes

New mattress
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.

Wonderfully comfortable mattress
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.

Bought as a replacement for my old mattress. I’ve had a Sealy previously so I knew I wouldn’t be disappointed. Excellent quality. Highly recommended.

Bought this as I was suffering from aches and pains, with it saying it specifically helped. Made it worse but it has now given my wife terrible backache/pains near her shoulders, ended buying a topper to try and make it softer. Obviously the bed is too firm, quality and workmanship of the mattress is good but overall it hasn’t brought me or the wife a good nights sleep.

Hi Alan,
Thank you for your review.
We're really sorry to hear that you are finding your new mattress too firm for your requirements.
A topper should help provide additional luxury where required, however if this is not the case we would recommend contacting the retailer to discuss your options further.

Thank you for your review,
Mattress fillings and components will naturally bed themselves in, especially in the areas where body weight is concentrated, however it should not be detrimental to the performance of the mattress.
If you feel the mattress has softened excessively, please do get in touch with the retailer who will investigate further.
If you need any further assistance, please don't hesitate to contact us at customercare@sealy.co.uk
