DreamCloud vs Sealy: Which Mattress Has the Features You Need?

Do you long for a mattress that can give you luxury softness? Or do you need a mattress that can deliver on its anti-allergy promises?

Here, we’re looking at two big-name mattresses, the DreamCloud Luxury Hybrid and the Sealy Olympia Geltex mattress. They both have different features, so let’s dig into the DreamCloud vs Sealy data and see which mattress will fit your needs.

Our Highlights of DreamCloud vs Sealy:

You Might Love the DreamCloud Luxury Hybrid if:

  • You want a sleep trial to beat all others. You have 365 nights to try the DreamCloud mattress in your own home.
  • You like a “Forever” relationship with your mattress. DreamCloud offers a “Forever” warranty so your mattress is protected for longer.
  • You’re thinking of your budget. DreamCloud allows you to order directly from them, meaning that they cut costs to deliver a quality mattress for less.

You Might Love the Sealy Olympia Geltex if:

  • You are concerned about allergies. Like many in Sealy’s range, the Olympia is recognised by the Allergy UK for its allergen reducing properties.
  • You’re thinking of your back. The Olympia is a Posturepedic mattress to give you extra back support.
  • You enjoy staying cool during the night. Gel mattresses can provide better cooling, especially when you’re first settling down for the night.

Mattress Construction: Peeling Back the Layers on the DreamCloud and Sealy

The DreamCloud Luxury Hybrid

The DreamCloud Luxury Hybrid contains five major layers, each designed to do a specific job.

The first layer is a quilted top cover that contains phase change materials to draw in heat from your body and help you sleep cooler.

The second layer is a breathable memory foam layer that aims to give deep contouring. The next layer is a foam support layer to underpin the memory foam layer and ensure you feel cradled throughout the night.

These layers are followed by 15cm ActiveEdge coils to give targeted comfort while also providing edge support so you don’t slip off the bed.

Lastly, the DreamCloud Luxury Hybrid sports a support foam base layer which helps to give you even more support. This last layer also tries to further reduce motion transfer.

This is a single-sided mattress meaning you don’t have to flip it.

The Sealy Olympia Geltex

Unfortunately, Sealy doesn’t go into detail on the construction of its mattress. Here’s what we do know though.

The Olympia contains a 4cm Geltex layer to add breathability, pressure-point relief, and support.

The Olympia also contains a layer of individually wrapped pocket springs, with the King containing up to 1000 individually wrapped springs. The number of springs will scale depending on the size of the mattress you buy.

The Sealy is labelled as Posturepedic, which means it has been designed based on insights given by orthopaedic specialists.

The Sealy also contains Purotex technology that comes with natural probiotics. These probiotic microcapsules break open when you lie on the mattress and quickly get to work to reduce common allergens like those from dust mites.

The Sealy is quilted to provide a comfortable sleep surface. It contains Tencel cellulose fibres which are more breathable than traditional fibres and also wick away moisture.

The mattress also has zonal support to keep your spine supported and aligned correctly for pain-free sleep.

This is a single-sided, no-turn mattress.


The DreamCloud Luxury Hybrid has a depth of 29cm. The Sealy Olympia Geltex mattress is slightly deeper at 30cm.

While these sizes are not unusual on the market they are on the larger end of the scale. It is always best to check that your bed frame can accommodate your chosen mattress. Please be aware that there can be a +/-2cm tolerance on mattress measurements.



On a standard scale measuring firmness where one is the softest and 10 the most firm, DreamCloud rates its Luxury Hybrid mattress as 6.5 or “luxury-firm”. This matches DreamCloud’s usual medium-firm rating.


The Sealy Olympia Geltex is also rated as a medium-firm mattress. In both cases, individual factors may change your experience of the mattress, but medium-firm is usually a good fit for most sleepers.

Edge Support


The DreamCloud Luxury Hybrid incorporates ActiveEdge technology in its coil spring system. It combines this with premium memory foam. The two together are designed to provide you with even support across the sleep surface.


The Sealy Olympia Geltex mattress uses a gel foam layer together with pocket springs. Like the DreamCloud, we would expect this combination to have fair to good edge-to-edge support, but edge support is not specifically included in the design specifications of the Olympia Geltex so we cannot draw any firm conclusions.

Motion Transfer

The introduction of pocket springs into any mattress will usually lead to more freedom of movement. This is a great addition to memory foam’s contouring and can stop you from feeling trapped.

However, by increasing your ability to move freely, pocket springs may also increase the possibility of motion transfer unless steps have been taken to insulate that movement.


Due to the layers of foam in the DreamCloud Luxury Hybrid, together with the fact that its coils are encased, we would expect that while there may be some motion transfer it will not be an overriding concern for most sleepers, though individual experiences may vary.


Similar to the DreamCloud, the Sealy Olympia Geltex uses gel foam together with a pocket spring layer. Any motion transfer may be offset by the foam layers and the way the springs perform but, without more information, we cannot draw firm conclusions on motion transfer.

Breathability & Temperature


The DreamCloud Luxury Hybrid’s quilted cover incorporates so-called phase change materials. These materials pull in and store heat to keep you cooler throughout the night.

The science on whether phase change materials deliver on this promise is mixed, but individual experiences may vary.

The DreamCloud Luxury Hybrid also incorporates foam that adds more breathability, as well as its coil system which may increase air circulation within the mattress and help to improve temperature control.


The Sealy Olympia Geltex mattress has several design features that may keep you cool throughout the night.

One feature is the 4cm Geltex layer. Geltex is an air-permeable foam combined with gel. The gel takes heat from your mattress and stores it to give you a fresher night’s sleep. Gel foam tends to work best at the beginning of the night, with its cooling effect tapering off throughout the night.

However, the Sealy Olympia Geltex also contains Tencel or lyocell fibres. These fibres are made from eucalyptus and are cooler than many other materials. They can also wick away moisture.

These features, combined with pocket springs and Sealy’s own-brand cooling fibres may mean that the Sealy Olympia Geltex delivers a comfortable temperature for longer.

Overall Mattress Comparison & Review


The DreamCloud Luxury Hybrid is designed to provide comfort to all sleepers. While the memory foam feel isn’t for everyone, if you are someone who craves the memory foam hug, DreamCloud’s multi-layered approach teamed with its ActiveEdge system is designed to blend contouring and responsiveness.

Compromises come in the form of a limited product range, a lack of EU sizing, and the potential for more motion transfer than traditional memory foam.

DreamCloud offsets these potential pitfalls with the promise of edge-to-edge support and more breathability than the traditional memory foam. It sets itself apart from the Sealy the most, however, with its 365-night trial and the “Forever” warranty.


The Sealy mattress is designed to provide extra back support. Together with its cooling Geltex and breathable, hypoallergenic fibres, this mattress is all about creating a comfortable, supportive and pain-free sleeping environment.

The Sealy Olympia Geltex doesn’t just claim to be hypoallergenic, either. It has been certified by the group Allergy UK for its ability to reduce the presence of dust mites. That means you can have confidence that the hypoallergenic label means something.

Sealy offers a wide range of mattresses that incorporate many of the features here, so you are likely to find an equivalent mattress in a store near you if the Olympia isn’t available to try.

One other drawback of the Sealy is that it does not offer easy access to detailed information on what is actually in its mattresses.

Pricing and Sizes

Below we show the available sizes and prices for the DreamCloud vs Sealy. Prices are correct as of 13/04/2021 but are subject to change.

Size (Width x Length) DreamCloud Luxury Hybrid


Sealy Olympia Geltex


Single (90 x 190cm) £549 £509
Double (135 x 190cm) £649 £679
King (150 x 200cm) £749 £713
Super King (180 x 200cm) £849 £959



DreamCloud uses top quality foams together with its spring technology to deliver a high-end mattress. Despite this, it is lower in cost than many on the market. The prices above are taken from the DreamCloud website and show that, for a hybrid mattress that focuses on softness, this mattress is competitively priced.

You will find mattresses cheaper than the DreamCloud, but they often do not use quality foams and don’t come with the same “Forever” guarantee.


The prices for the Sealy here are illustrative based on one retailer’s pricing, but they give a sense of the price bracket for this mattress.

When we compare the Sealy Olympia Geltex to other mattresses, we see it is competitively priced given its Geltex layer and the anti-allergy properties in its fibres. It goes toe-to-toe with the DreamCloud until the Super King size.

All that said, the Sealy does not come with a sleep trial and has only a five-year guarantee. You will need to be sure the Sealy is for you when you order it, so the investment may be slightly more of a risk than with the DreamCloud. Your investment may not last as long, either.

This may make the Sealy Olympia Geltex more expensive in the long run, though this is a personal thing depending on what features you value.



At the time of writing, DreamCloud is offering a free “no-contact” service to most UK mainland addresses where a delivery driver will leave your boxed mattress on your doorstep. The current shipping time is around two working days.

DreamCloud is not currently offering its two-person service due to Covid-19 safety concerns. This is subject to change based on government advice.

DreamCloud does offer a service to take away your old mattress. There is a fee of £35 for this service, and it is made available at the time of check-out.


The delivery service offered to you for your Sealy mattress may depend on the store from which you buy it.

When Sealy is delivering directly, it offers free delivery within 14-21 days. Under normal circumstances, Sealy operates a two-person delivery service that can take your mattress to your room and help set it up. The team will also remove any packaging.

This service is available to most mainland postcodes in England, Scotland, and Wales, though some restrictions apply and if you live outside the areas covered you may have to pay an additional charge.

Different delivery options may be provided due to Covid-19 safety concerns.



DreamCloud allows for traditional returns as well as returns under its 365-night trial and “Forever” warranty. All of these can be accessed by contacting the DreamCloud customer service team through DreamCloud’s website.

Remember that returns are subject to terms and conditions and you may need to show proof of purchase as well as provide reasons and evidence for your return.


Sealy allows returns up to 14 days after you receive your mattress. You can contact the customer care team through Sealy’s website. If you bought through a store, you may need to contact the store first to find out the way forward for your returns procedure.

Returns under the five-year warranty should go through the retailer from whom you purchased your Sealy mattress.

Sleep Trial


The DreamCloud Luxury Hybrid comes with a 365-night sleep trial. This means that after 30 days of receiving your mattress and within the limits of the trial, you may return your mattress for whatever reason (subject to terms) if you are not completely satisfied.


The Sealy Olympia Geltex does not come with a sleep trial. While there may be valid reasons for this, a sleep trial is quickly becoming a must-have feature among big-brand mattresses, so its lack here may put you off.

You may however be able to try out Sealy mattresses in some stores.


It’s really important with warranties that you take the time to understand your obligations. For example, standard requirements include that you must place your mattress on a suitable bed frame. Other requirements can be that you rotate your mattress regularly to ensure even wear.


DreamCloud’s “Forever” warranty is one of the leading on the market. It promises that, if your mattress develops a fault within the first 10 years of you having your mattress, DreamCloud will replace it at no cost to you.

After those 10 years, DreamCloud will recover, repair, or replace your mattress. You may incur charges for transportation of the mattress but, if the problem is the result of a manufacturing fault or material defect, DreamCloud will waive those fees.

The warranty does not cover things like improper use, or loss of perceived comfort related to age.


Any claims under Sealy’s five-year guarantee must be made through the retailer from which you purchased the mattress. You will need to ensure you have proof of purchase to make a valid claim.

If you purchased directly from Sealy, you can contact the customer care team directly with proof of purchase and photos of the issue.

Sealy covers issues that arise due to a fault in manufacturing or materials. It will not cover you if the mattress is deemed unhygienic or if it has been improperly used by, for example, being bent or mishandled.

Final Thoughts

The DreamCloud Luxury Hybrid and the Sealy Olympia Geltex mattresses are both solid choices, each with their strengths.

The DreamCloud provides comfort at an affordable price that is backed up by a market-leading 365-night sleep trial and a “Forever” warranty, but it doesn’t focus on preventing allergies like the Sealy or providing tailored back support.

The Sealy Olympia Geltex may be a good option if you require a mattress that is endorsed by Allergy UK for its ability to give you a healthier night’s sleep. It may also be suitable if you want Geltex cooling and firm support. This mattress isn’t going to give you the plushness of the DreamCloud, though.

The choice between these mattresses comes down to personal preference. If you want a mattress to last you long term, the DreamCloud seems a good fit. If you need specific back support and a low-allergen mattress, the Sealy may be the dream mattress for you.
