What our reviewers found

Pros

  • This mattress strikes a perfect balance of firmness and softness as needed, providing sleepers with overall comfort and support.
  • Well-regarded for its excellent value for money, blending quality construction and materials without having you overpay.
  • The quality memory foam used in its construction offers a premium, luxurious experience of comfort and support.
  • Its consistent good quality and performance reinforce the strong reputation that Komfi mattresses are known for.
  • Finally, customers appreciate the favourable price point given the high-grade, deluxe nature of this specific Komfi mattress model.

Cons

  • The 17cm depth of this mattress might not provide sufficient support for heavier individuals, potentially leading to discomfort over time.
  • While the mattress has cooling properties with its Neuform memory foam, those with a tendency to sleep hot may still find memory foam mattress types retaining excessive heat.
  • Although the mattress is medium to firm, some sleepers, especially side sleepers with an hourglass figure or people with specific joint ailments, might require a softer mattress for better pressure relief.

If you're searching for a mattress that provides both restful comfort and awesome value, the Komfi Unity Memory Deluxe Mattress might be what you've been hunting for. But before you make a decision, you might want to know a little more about this potential new addition to your sleeping routine.

Design and Features

The Komfi Unity Memory Deluxe mattress is unique in its combination of both clever mattress technology and sustainable design principles. The mattress measures at a depth of 17cm and is composed of a collection of various foam layers, each contributing to the overall comfort and support provided by this mattress.

At the top tier of the model, the specialised Neuform memory foam provides an initial layer of snug support for your body. This cloud-like layer of support works to alleviate pressure on key tension areas such as joints and muscles, promoting relaxation and peaceful sleep.

Another integral layer in the heart of this mattress is its reflex foam. This foam contours to your individual shape, absorbing movement and limiting disturbance from other movements on the bed for uninterrupted sleep, night after night.

The Komfi Unity Memory Deluxe mattress manifests commitment to sustainability through its bottom layer of recycled eco foam. This layers provides firm support and a clear conscience knowing your sleep is contributing to less damage on the environment.

Mattress Comfort

When it comes to firmness, the Komfi Unity Memory Deluxe mattress takes a balanced approach with a medium to firm rating. This level of firmness is versatile and can accommodate various sleeping positions. Whether you're a back, side, or front sleeper, this mattress has got you covered. Its blend of sturdy support and plush comfort sets high bars for other mattresses on the market in terms of versatile appeal.

The mattress is designed to be easy to care for with a single-sided design. The mattress only requires rotation from top to toe every month to maintain its quality, reducing the stress around the upkeep, typically associated with other models.

Suitability

From my perspective, this mattress would suit a variety of sleepers. It is particularly ideal for those who enjoy a firm yet comfortable foundation to sleep on but don't drastically fall on either end of the firmness spectrum. It strikes a balance between offering the clouds' softness and the ground's firmness. Specifically, this mattress would support side and back sleepers of average weight very well. However, piled-up side sleepers might want to consider a gentler option.

What customers thought

Owners mostly call it comfortable, and several are pleased with how firm it is. "Its very firm but that is what I wanted," one owner wrote, while another called it a "Great comfortable firm mattress." The complaints are about the same thing. One owner said only that it "Was too firm". Another wrote, "It is supposed to be medium and it’s like trying to sleep on the floor." Value comes up often, with one owner describing a "great price for the quality" and another writing, "Very comfy memory foam deluxe mattress for the price." Some owners use it on a spare or guest bed, and delivery arriving on time gets a few mentions.

The Verdict

Finishing with my personal insights, it's clear that this budget-friendly offering from Komfi provides a decent density of memory foam at a price that doesn't break the bank. While some may find that the memory foam layer induces a bit of heat, those who don't typically sleep hot should find this a non-issue.

This mattress offers incredible value. It strikes a perfect balance between price and quality, making it an attractive choice. However, potential buyers should keep in mind that the mattresses firmness would be more suitable for average weighted people. As always, it's essential to consider personal comfort preferences when investing in a new mattress.

Suitability

  • Back Sleepers 4/5
  • The amount of support offered from a mattress will vary depending on the firmness of the tension and the type of support layer used. Based on a person of average build.
  • Side Sleepers 4/5
  • If you sleep on your side you typically need a supportive tension that is not too firm, nor too soft. This is because your hips and shoulders need adequate sinkage.
  • Stomach Sleepers 4/5
  • Stomach sleepers need a reasonable amount of tension in the base support layer to adequately offer body contouring and help prevent aches and pains. Results will vary based on your build.

Performance

  • Breathability 3.5/5
  • Mattresses that feature breathable materials help promote airflow and keep you cool making for a more hygienic night's sleep.
  • Turning on mattress 3.5/5
  • Certain materials like memory foam can make it difficult to move about on the mattress while you toss and turn. Same too for pillow tops which can create a cloud like sensation which can make manoeuvrability challenging.
  • Stability 4/5
  • Depending on the type of support layer in place can have an impact on stability, edge to edge support and roll together prevention. Pocket springs of a firmer tension will have better stability than open coil soft tension, for example.

Odour

  • Initial Odour 3/5
  • Materials in mattresses, particularly memory foam and rolled bed-in-a-box mattresses can have an initial odour, this is typically short term and reduces considerably within 24 hours.
  • Long Standing Odour 4.5/5
  • Certain materials inside different mattresses can produce a small odour. Typically this is short term rather than long standing but there are minor exceptions.

Brand Rating

  • Overall Brand Rating 4.5/5
  • This is based on community driven customer reviews tied to product reviews and grouped together at a brand level to produce a score.

This is the most uncomfortable mattress I have ever had. It is supposed to be medium and it's like trying to sleep on the floor. Do not purchase unless you want a very hard mattress

Mattress came well packaged and was clean and complete when opened. It's for a spare bed and so I haven't actually slept on it but it feels comfy when lying on it.
