dosleeps King Size Mattress 5FT (150x200x27cm) – Extra Thick Memory Foam & Pocket Sprung, Medium Firm 9‑Zone Support

The essentials

If you’re shopping for a king size mattress that’s trying to balance support and sleep comfort, the dosleeps King Size Mattress 5FT is worth a look on paper. It pairs individually pocketed spring coils (arranged into a 9-zone support system) with a layer of extra memory foam on top, aiming to reduce pressure and movement disturbance. The headline idea here is pretty clear: zoned support for your body shape, plus motion isolation so you’re less likely to feel your partner’s restless nights.

It’s also presented as a “Tencel surface” mattress, which matters if you tend to run warm at night. The brand claims the TENCEL Lyocell fibres absorb moisture more efficiently and help with the body’s thermal regulating mechanism.

That said, without reviews or firmness/comfort tester data, you’ll want to treat it as a medium-firm option that could suit many people, but may not feel right if you prefer a softer “hug” or a much more plush top layer.

What to know about the support system

The mattress uses a 9-zone support system built from individual pocketed coils. Each spring coil is made of tempered stainless steel wire and placed into a bucket shape, then compressed and sealed in a fabric pocket. The purpose of the pocketing is twofold: reduce noise from coil collision and isolate movement between zones.

On the comfort side, the pocket coils are described as individually and independently wrapped, so they can contour around different parts of the body. The claim is that this helps eliminate pressure points and can reduce motion disturbance—so if you’re the sort of sleeper who wakes when someone shifts position, this is the type of mattress that’s designed to reduce that “wave” effect.

There’s also mention of an 9-zone approach for “orthopedic support”. That’s a broad promise, and in real life it usually comes down to whether the firmness level and the way the top layers behave match your weight distribution.

Comfort layer: extra memory foam (and what to expect)

On top of the pocket springs, there’s an extra memory foam layer. The manufacturer says it can reduce up to 87% of pressure on the neck, spine and hip area, and that the foam absorbs pressure to reduce body turning during sleep.

For buyers, the practical takeaway is that this is positioned as a pressure-relief comfort build—not just a “springs only” mattress. Memory foam can feel more enveloping and can help with aches for some sleepers, but it can also feel warmer or slower to respond depending on the overall foam thickness and your preference for bouncy support. With only the marketing claims available here, it’s a little hard to predict exactly how “active” it will feel compared with springier options.

Motion isolation and edge support: the day-to-day difference

The mattress is explicitly marketed for motion isolation. Because each pocketed coil is individually wrapped, the idea is that you’ll experience less motion transfer if a partner moves at night.

Edge support is also mentioned in the product title, which matters if you tend to sit on the edge when getting ready, or if you use the full sleeping surface rather than staying centred. However, the details provided don’t explain how the edge is reinforced—so it’s best to consider this as a positive signal rather than a guarantee.

Tencel surface for moisture and temperature

The “Tencel surface” is a specific point of differentiation. The brand claims the smooth fibre surface of TENCEL Lyocell absorbs moisture more efficiently, supporting the body’s natural thermal regulating mechanism. The expectation, in plain terms, is a cooler, drier feel through the day and night.

If you’ve previously found that certain mattresses hold onto warmth, this is a reasonable feature to focus on. If you’re very cold at night, though, you may not automatically find it “warmer”—it’s designed to move moisture and support temperature regulation.

Who it suits best (and who should pause)

It’s a good fit if you want a king size mattress with a zoned pocket spring base, plus a memory foam top layer aimed at reducing pressure and partner movement. The medium firm positioning also suggests it may suit a wide range of sleeping styles—especially if you like the idea of support that’s not overly soft.

It may not be the best match if you strongly prefer either a very plush mattress (more immediate sinking and softer comfort) or a very springy, minimal-foam feel. It also might not suit you if you dislike memory foam’s characteristic feel—dense, contouring and slower response—because that’s the comfort direction it’s clearly leaning into.

A small limitation to keep in mind: we only have the trial information and feature claims, not measured outcomes. So it’s the sort of purchase where the 100-night sleep trial (mentioned in the base description) becomes especially important.

Should you buy it?

Consider buying the dosleeps King Size Mattress 5FT if you’re after a medium-firm, extra-thick comfort setup with pocketed springs in a 9-zone arrangement and a memory foam top for pressure relief and reduced motion disturbance. It’s particularly sensible if you care about temperature/moisture management and you want something designed to keep you and your partner from feeling each other’s movements.

You may want to skip it if you know you prefer a firmer “bouncy” feel without memory foam contouring, or if you’re looking for a mattress that’s clearly described in terms of exact thickness breakdown beyond “10.6" extra thick” and overall dimensions. In those cases, a different comfort style could fit you better.

If you do buy, the practical approach is simple: use the sleep trial to check whether the pressure relief and medium-firm feel actually match your sleeping position and body type. That’s the only safe way to confirm the fit, especially with memory foam behaviour varying so much person to person.

FAQs

How firm is it?

It’s described as medium firm. That’s a useful starting point, but firmness can still feel different depending on body weight, sleep position and how you perceive memory foam.

Does it help with partner movement?

The mattress is marketed for motion isolation, with individually wrapped pocket coils intended to reduce motion disturbance if someone moves during the night.

What’s the benefit of the 9-zone design?

The 9-zone support system is meant to provide targeted support across different body areas, while the pocketed coil build is also designed to reduce noise and movement transfer.

What does the Tencel surface do?

The Tencel Lyocell surface is claimed to absorb moisture more efficiently and support temperature regulation for a cooler, drier feel.

How long can you try it?

A 100-night sleep trial is mentioned, which is particularly important if you’re unsure about how the memory foam will feel for you.
