Doubleslee Memory Foam Mattress 5ft King
Product description
A medium firm memory foam mattress can help you get comfortable through the night, and the Doubleslee memory foam mattress is built around that idea with a pressure relieving top layer. If you like the feeling of being supported without feeling too hard, this 5FT King mattress is designed to contour to your body and support your sleep routine. It also comes in a practical in a box format, so setup is straightforward when you move rooms or want a simple replacement.
The construction described by the manufacturer focuses on a double layer foam system. There is a gel memory foam comfort layer, followed by a high density support layer meant to provide consistent backing. This combination is designed to reduce pressure points, ease everyday fatigue and stress, and create a cooler, more comfortable sleep feel. It’s also presented as hypoallergenic and breathable, with a cover that uses breathable holes to encourage airflow, which can matter if you tend to sleep warm. 😊

The essentials
What stands out about this Doubleslee mattress is the way the comfort layer is described to work with your body. The gel memory foam layer is described as soft and designed to be tailored to your contours, which can help reduce pressure points where your body makes the most contact. Many people find that memory foam support like this helps them feel less tense in the evening, then wake up feeling more settled.



The second layer is a high density foam support base, described as providing a solid, reliable foundation. Because it is intended to offer even support across the sleep surface, it can help maintain a steady sleeping feel from one night to the next. Alongside that, the manufacturer also highlights breathability and impact absorption properties, aiming to support a more comfortable sleep environment with less heat build up.
Finally, the in a box approach is meant to make delivery and access easier. Once you open the box, you are advised to wait 48 to 72 hours for the mattress to expand fully. That expansion time is part of the intended setup process, and it helps you get the mattress back to its proper shape for everyday use.

Key features
The comfort layer uses gel memory foam, and the manufacturer describes it as very soft while adapting to your body’s shape. This type of contouring is often chosen for pressure relief, because it spreads your weight more evenly across the surface. The stated goal is to reduce pressure points and create a sense of floating, which can feel especially helpful if you experience stiffness after a long day.

The support layer is described as high density foam with good breathability and impact absorption. That means it is intended to provide uniform support rather than a patchy feel. The manufacturer also links this layer to regulating temperature and moisture, aiming to keep the sleep surface more comfortable through the night, particularly during warmer conditions.
On breathability and comfort, the cover is described as hypoallergenic, with breathable holes. The manufacturer states it is made without harmful substances and meets the main industry standards. That emphasis on a fresh, breathable sleeping surface is a practical choice if you want a mattress that feels less stuffy, day to day.



Durability is another point the manufacturer makes clearly. The mattress is described as carefully designed and manufactured to maintain its form and support properties over time, even with frequent use. A further reassurance is offered through a replacement service if you find an issue during use, including scenarios like if it is stepped on and folded, with free replacement support promised by the manufacturer. ✅
Worth noting, sleep comfort is personal, so the medium firm feel may suit you best if you prefer a balanced support level rather than a very soft or very hard feel. It may not feel right if you only want a softer top that sinks deeply or if you prefer a traditional springier bounce. Still, the stated combination of gel memory foam comfort and high density support is designed to keep both comfort and backing in mind.
What’s included
This mattress is sealed in vacuum packaging, compressed for delivery, and placed into a compact cardboard box for easier transport. After you unpack it, you should allow 48 to 72 hours for full expansion, as recommended by the manufacturer. The practical packaging approach is meant to make it easier to get the mattress into your home with less hassle.
Who it’s for
It’s a good fit if you want a memory foam mattress with a gel comfort layer that is described as contouring and pressure relieving. It suits you if you like medium firm support and you want a stable feel supported by a high density foam base. You may also like it if you value breathability and hypoallergenic materials, especially if you tend to notice heat or discomfort when sleeping.
It might not be a great match if you prefer the feel of a fully breathable latex mattress or a very springy innerspring bounce. If you want a very plush sink in feel, you may find the medium firm profile less soft than expected. For best results, allow the expansion time and give the mattress a little time to settle into your routine.
