To help you decide, here are a few of the features that stood out to us about the Sealy Olympia Geltex and the OTTY Pure Hybrid Bamboo & Charcoal.

Mattress Construction: What’s Beneath Those Sheets?
Sealy
Sealy’s website doesn’t provide a detailed breakdown of what’s inside its mattresses, but here are some highlights.
The Sealy Olympia Geltex is micro-quilted and contains Tencel fibres. Tencel is a brand name for a type of lyocell fibre made from specially treated and processed wood pulp. In this case, the wood comes from eucalyptus. Tencel reportedly feels silky but is also very breathable and can remove moisture.
The Sealy contains a 4cm layer of gel-infused foam called Geltex. Championed by Sealy and Silentnight, Geltex is a viscoelastic material that will change to accommodate your body shape. The mattress may be a good option for people who want to reduce pressure point pain while they sleep.
The foam in Geltex contains a type of gel that can trap heat. If you want to stay at a comfortable temperature throughout the night, this feature might help.
The Olympia Geltex is from Sealy’s Posturepedic range that puts correct spine alignment and comfort at the forefront of the design. Sealy tests its Posturepedic ranges to ensure their durability, something that is particularly important for your back health as you need the materials to stay consistent to offer proper support.
Sealy also treats its Olympia Geltex with Purotex.
A probiotic technology, Purotex fights allergens in the Olympia Geltex. Allergy UK acknowledges Sealy’s Purotex-treated ranges for fighting household dust mites. Tests have also shown Purotex may be effective in reducing exposure to cat and dog allergens.
The Sealy Olympia Geltex also contains pocket springs, with the King size containing up to 1000 pocket springs. The addition of pocket springs in a mattress can help to give more freedom of movement on the bed surface. Springs can also offer support for different areas of the body.
Sealy notes this kind of “zonal support” is a strength of the Sealy Olympia Geltex.
The Sealy is a single-sided mattress. You do not have to flip it over.
OTTY
The OTTY Hybrid Bamboo & Charcoal Mattress contains five specially designed layers and a foam base
The first layer is an embroidered cover layer. This layer contains charcoal for its antibacterial properties, though how effective charcoal is at this task has not been independently evaluated yet. The cover is removable but is dry-clean only.
The next layer is a bamboo memory foam layer which also contains charcoal. OTTY says this is the first time a UK manufacturer has used this combination of materials in this way to make a mattress.
OTTY designed this layer to try to improve breathability in the mattress and keep you cool during the night. Bamboo is considered to be a more sustainable alternative to many traditional foam mattress materials.
Following that is OTTY’s “Reflex Foam” support layer. This combines with the next layer of up to 2000 springs to give you targeted support across the sleep surface. The foam and spring combination may also reduce motion transfer so your partner shouldn’t feel it when you move.
The last of the layers is a side support layer to help you use all of the mattress without feeling like you might roll off the sides. This layer also contains OTTY’s “Airflow” technology to improve breathability.
To keep all of this exactly where it should be, OTTY has a foam base in its design.
The OTTY is a single-sided mattress.
Thickness
The Sealy Olympia Geltex is 30cm in depth.
The OTTY Hybrid Bamboo & Charcoal Mattress is 25cm in depth.
Firmness
The Sealy Olympia Geltex is a medium-firm mattress.
OTTY rates its Hybrid Bamboo & Charcoal mattress 6.5 on a scale of one to 10 where one is the softest feel and 10 is the firmest. This score makes the Otty a medium-firm mattress that may be suitable for most sleepers.
Edge Support
Sealy
Sealy does not offer specific information on edge support for the Sealy Olympia Geltex.
OTTY
OTTY designed a layer in its Hybrid Bamboo & Charcoal Mattress to give you side-support so that you can use the full sleep surface.
Motion Transfer
Sealy
Sealy does not tackle the issue of motion transfer in its descriptions of the Olympia Geltex, but the combination of Geltex foam and high-quality pocket springs may mean you won’t feel much motion transfer from this mattress.
OTTY
OTTY says its design combines high-quality foams and springs in such a way as to reduce motion transfer so that you will not be troubled if a sleep partner moves or turns over.
Breathability & Temperature
Sealy
Geltex is a foam infused with gel. The gel in this foam draws in heat which may help you stay cooler, particularly at the start of the night. You may find as the night goes on this cooling effect is reduced, though.
The Tencel fibres in the Sealy aim to wick away moisture and improve breathability, while pocket springs in this mattress may also help to circulate air.
OTTY
The OTTY uses bamboo and charcoal in its design, both of which may improve breathability. The OTTY Hybrid Bamboo & Charcoal Mattress also contains an edge support layer that has Airflow technology. Together with the spring layer, it may help to circulate air through the mattress.
Overall Mattress Comparison & Review
OTTY’s Hybrid Bamboo & Charcoal mattress delivers several premium features. It seems targeted as a more luxury mattress for the general market and aims to suit most sleep styles and needs.
The Sealy Olympia Geltex mattress is trying to do slightly less but do it well. The Sealy is a Posturepedic mattress that puts spine health at the centre of its design. It also tries to create a breathable and clean sleeping environment by using lyocell fibres and probiotic technology.
OTTY says its mattresses are hypoallergenic, making the Hybrid Bamboo & Charcoal Mattress “perfect” for people with allergies.
Hypoallergenic is a catch-all term that companies use to indicate their products do not contain materials that are likely to cause allergies. You may also see the hypoallergenic label if materials in the mattress have properties that may reduce the number of allergens you are likely to encounter.
For example, foam mattresses tend to be dense and restrict allergens from building up in the mattress. We cannot confirm whether the use of charcoal in this mattress delivers additional protection, and this is not an area that has had much scientific study.
The Sealy, on the other hand, is not just hypoallergenic. The mattress is also anti-allergy, specifically when it comes to house dust mites.
The Olympia Geltex contains Purotex probiotic microcapsules that, when slept on, break open and release probiotics that soak up moisture and restrict the growth of bad bacteria.
Allergy UK acknowledges this Sealy range for fighting house dust mites.
If you are generally wanting a low-allergy sleep surface, both the OTTY and Sealy may fit your needs. However, if you specifically want a mattress that will restrict household dust mite allergens, you may find the Sealy range fits your needs better.
One other area worth mentioning about the Sealy and OTTY is their durability.
Sealy’s Posturepedic mattresses aim to provide support for your spine. Sealy emphasizes the durability of the materials it uses here. Sealy needs the materials to last for the life of the mattress without degrading in quality to give you the spine support you want from this mattress.
This may be why Sealy’s guarantee is only five years–it doesn’t want to overpromise what the mattress can deliver.
OTTY’s use of high-quality foams and springs, as well as a carefully engineered layer for edge support, may give confidence that the sleep surface will hold up through its 10-year life.
Now, let’s look at a few of the price and policy details to understand how these mattresses compare.

Prices are accurate as of 22/04/2021. Prices are from the OTTY website and a retailer for the Sealy mattress. Prices may vary.
Though Sealy is hitting all the standard UK sizes, Sealy’s size range is smaller than OTTY’s on this mattress comparison. Otty’s inclusion of EU sizes may be particularly pleasing as it allows you a potentially wider choice of bed frames.
In terms of price, while OTTY’s Pure Hybrid Bamboo & Charcoal Mattress is consistently more expensive than the Sealy, the gap isn’t a large one. For the features in these mattresses, you are getting a lot for your money.
OTTY’s mattress may be a better long-term investment because the warranty is longer.

Sleep Trial
Sealy
Sealy does not offer a sleep trial for the Olympia Geltex.
OTTY
OTTY offers a 100-night sleep trial for the Hybrid Bamboo & Charcoal Mattress so you can try the mattress at home and, if you are not completely satisfied, return the mattress for your money back.
The OTTY trial comes with specific terms that are arguably more stringent than others we have seen.
A cleaning fee may be deducted from your return payment if OTTY feels cleaning your returned mattress is necessary. OTTY may also refuse to honour the trial if you return the mattress soiled past the point of cleaning. Other stipulations apply.
The 100-night warranty is only available for UK and Ireland mainland residents and may be subject to postcode restrictions.
The company will work with you to collect your mattress if you do wish to return it. Once inspected, OTTY will process your refund usually within 14 days of receipt of the mattress.
Warranty
Sealy
Sealy offers a five-year guarantee for the Olympia Geltex. This covers any defects that are the result of material or construction faults.
The guarantee does not cover improper use of the mattress. For example, using an unsuitable bed base. You’re also not covered if the mattress is soiled or damaged.
To claim under the Sealy warranty you must go through the outlet from which you purchased your mattress. If this was Sealy, start the process by contacting Sealy’s customer service team.
OTTY
OTTY offers a 10-year guarantee on its Hybrid Bamboo & Charcoal Mattress.
OTTY’s warranty covers sags or dips in the foam layers of the mattress that are more than one inch (2.5cm). It also covers instances where a spring in the mattress has broken or malfunctioned.
Mattresses that do not recover to their advertised size after being compressed may be covered if the compression is over a tolerance of 3cm.
The guarantee may also cover defective stitching.
OTTY makes clear in its terms that to maintain your mattress you must adhere to the care guidelines. The instructions include rotating your mattress head-to-toe once every month for the first six months. Regularly rotating your mattress can help the mattress age evenly and prevent dips from forming.
Final Thoughts
The Sealy and OTTY mattresses come with a lot of nifty features that can help you to sleep soundly.
The Sealy Olympia Geltex emphasizes caring for your back while giving you a healthy sleep surface. The mattress also contains Purotex which can help to reduce allergens.
The OTTY costs slightly more than the Sealy but arguably makes up for it with the 100-night sleep trial and a 10-year warranty. The layered design of this mattress caters for many different needs and might be particularly good if you and your sleep partner have different sleep styles.
Whether you choose the Sealy or the OTTY mattress, both have impressive features that could help give you a restful and relaxing night’s sleep.
