wowttrelax King 5ft 8 memory foam mattress

A king size memory foam mattress can make a real difference when your goal is comfort that feels consistent night after night. The wowttrelax king size mattress is built around layered foam for body contouring support, plus a removable cover that is designed to be easier to live with over time. With a medium firm feel and a fire resistant barrier, this mattress is intended for everyday sleep use in a standard king bed setup, measuring 150x200x20cm for a snug fit in most compatible frames. 🛏️

You get a soft touch fabric top, a construction that aims to balance pressure relief with support, and practical delivery and setup guidance using compression for easier handling. If you share a bed, the design also targets reduced motion transfer so you can both move and turn without fully waking the other person. It can be a strong option to consider if you want memory foam comfort with a removable cover and straightforward aftercare.

Key features

The surface fabric is described as OEKO-TEX certified, with a soft, breathable feel that helps you stay comfortable through the night. The cover is removable and washable, which matters for day to day hygiene and freshness. You can also expect a medium firm sleeping experience that aims to support natural body positioning rather than feeling overly hard.

Under the fabric, the mattress uses a two layer foam approach. The upper layer includes a gel memory foam component said to provide a close fit to your body, with a slow rebound feel that takes around 3 to 5 seconds. Below that, a high density support layer is designed to help distribute your weight more evenly.

It is also designed to suit different sleeping positions, including side sleeping, back sleeping, and stomach sleeping. If you like to switch posture during the night, the aim is to make those position changes feel smoother and more stable. 💤

What to know

When you unbox compressed mattresses, timing matters. The wowttrelax king size mattress is delivered compressed so the volume is reduced to around a quarter of the original, and you should allow 48 to 72 hours for it to expand fully. This helps it reach the shape intended for daily sleep and makes the first night more consistent. 🧊

Sleep comfort is closely linked to how pressure is managed, and this model is described as absorbing a high percentage of body pressure to help support your weight. It is also described as designed to help align the spine by distributing load more evenly across the mattress. If you are sensitive to pressure points, this is one of the reasons people choose memory foam mattresses for bedroom comfort.

The support core is described with air fibres and a three dimensional hollow technology approach to help improve breathability, aiming to keep the sleeping surface more comfortable. You should also take note that the performance you feel can depend on your body shape, sleep position, and how the mattress works with your specific bed frame and base. It is described as being made to support long term use and to avoid easy collapse.

For anyone who sleeps with a partner, the mattress is described as helping reduce disturbance from movement and turning. There is also a 100 day sleep trial service offered with the purchase, which can be useful if you want time to judge feel at home.

The included fabric and fire barrier are presented as safety focused elements, including a fire resistant barrier and non toxic, hypoallergenic positioning in the product description. If you are looking for a king size memory foam mattress that combines comfort layering with a removable cover, this wowttrelax option is worth considering as part of your shortlist. It suits side, back, and stomach sleeping preferences, with a medium firm feel that aims for a balanced, all night support experience.

When it’s a good fit

It’s a good fit if you want memory foam contouring with a medium firm feel, and you prefer the convenience of a removable, machine washable cover. It also makes sense if you like to change sleeping positions during the night and want pressure relief that targets multiple postures. You may want to skip it if you are looking for a very firm mattress feel without any slow rebound characteristics, or if you cannot allow the 48 to 72 hour expansion period after delivery.
