becky says

The Sealy Jenner Traditional Spring Mattress has cropped up in recent months and we've had a lot of interest since it's inception. Currently available from Dreams, this is a mattress that fits a lot of great specifications into lower than normal price point that will ensure you get a great nights sleep at an extremely reasonable cost.

Let's talk first about that support layer, made from traditional springs you basically have a support system that is a cage filled with springs. This is a time tested way of ensuring you get enough full-body support while also helping to keep costs down. I still have a personal preference to pocket springs when it comes to support but the savings made in this area or more than made up in luxury comfort layers. Effectively this mattress compromises a little bit on the support to give you more than typical fillings and comfort.

Onto that comfort layer and you technically have two. The first, memory foam. Memory foam is a great comfort layer that has been rising in popularity due to it's luxurious comfort offset against that cloud-like feel that many perceive to go hand-in-hand with memory foam. The second comes in the form of a pillow top, that pillow top is further separation between you and the springs. The more separation you have  with good quality and soft comfy fillings, the better your comfort.  I was fairly surprised to see the double-comfort layer playing a role here at this price and a very welcome addition to the Sealy line-up.

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews.

Key Performance Indicators

Our Key Performance Indicators are produced using a combination of specification-heavy algoritmic data points and user reviews. For example, a firm pocket spring support layer is more breathable and offers better back support but may prove unsuitable for side sleepers, the reverse is true for a soft-medium tension reflex foam support layer. This is one of 100+ datapoints considered when generating the below ratings.


*Assuming average weight, suitability will vary dependant on body type, use the wizard above for a more tailored guide.
  • Back Sleepers
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.


  • Breathability
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.


  • Initial Odour
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

Brand Rating

  • Overall Brand Rating
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

What Makes The Sealy Jenner Traditional Spring Mattress Great?

Sealy's PostureTech Core Support system

Mattresses that come with a Posturetech Spring System help to assist with supporting of all pressure points on a human body. The result of this is that you end up with a far softer feel on the mattress that will naturally get firmer with additional pressure. The end result is a supportive and comfortable product

Power Pack

Unique to Sealy this is a type of system that has zoned springs along with firmer fillings for the mattress. This means that you end up with some really enhanced lumbar support

Comfort Grade - Medium

A Medium firmness mattress is the most common build offered due to the range of suitability offered in such a mattress. This type of mattress will be better suited toward averagely weighted people, while lighter people should opt for a medium-light, and heavier people considering a medium-firm.

Rotate Regularly - Rotate head to toe weekly for the first three months, then every month thereafter

Your mattress should be rotated on a regular basis as this is the easiest way to prolong and increase the longevity of your mattress. The main benefits to regularly rotating your mattress is the continued support and comfort while reducing any risk of sagging that may otherwise occur

Sealy Care Guide

An easy-care guide will provide a walkthrough for keeping mattresses clean and dry. Provide instruction on rotating and/of flipping if necessary. Keeping furniture stable and safe where required.

About Sealy

Sealy has divisions across the world with renowned manufacturing within the high-end bed and mattress segment for over 100 years. For the UK division of Sealy, the mattress factory is inset within the heart of Cumbria which makes an impressive 3500 mattresses per week.

Comfort grade - Soft

A soft mattress will give you great comfort and can be a god choice. Remember though, the amount of firmness directly correlates to support and you are not going to get too much support from a soft mattress. This may be exactly what you need, but it's apersonal choice. Avoid if you suffer from any sort of back pain

Memory Foam layer

Something for the memory foam lovers. Who doesn't love a bit of sinky-floaty and supportive material designed to rebound again and again. Definitely the optimal for comfort in any mattress

Sumptuous pillow top

With a pillow top, this mattress effectively comes with it's own built-in protector. That's all a pillow top really is, an additional top layer of comfort which makes all the difference when it comes to getting that good nights sleep. We quite like pillow tops, they have their place in the industry. 

Single sided - Rotate head to toe weekly for the first three months, then every month thereafter

A single sided mattress is typical for the industry and relates to how  a mattress has the comfort layer on one side of the mattress. only This means that the mattress only needs to be rotated rather than flipped. The benefit of single sided mattresses is that they require less upkeep in that there's no flipping, but also, there's less components involved in the creation which saves costs.

Online only

This mattress is not sold in stores and is instead an online-only model. That works quite well for us, since our core line-up or reviews and specification highlights are all based around online models.

Made in the UK

These are made and manufactured in the UK, meaning that they all meet the same exceptional quality and durability that we expect from genuine UK manufacturing.

Comfortable and well made mattress

Lovely mattress. On the firmer size of medium I would say. Used in a spare room and seems very comfortable. Delivery was on time and we were updated really well. The old mattress was taken away and the whole experience was great.


Our old mattress must have been really bad as the difference now is amazing. At first I thought it a bit too firm but after a few nights realised what we had been missing . Bought 2 , to use the other in our spare room .
