The Best Mattresses

So, you want your bed to feel like you’re on cloud nine? I can see your dreams coming true with the vast choices for the best soft mattress UK offers. 

After a long day at work, all my girlfriend wants is a bed to relax on and carry on with her exotic nighttime self-care routine. I’m sure that’s all you want too! 

A hard mattress won’t hold my girlfriend and me, as a matter of fact. It can get uncomfortable and make falling asleep even more challenging.

A mattress that cushions you while ensuring proper support for your spine is essential for any ideal mattress. 

Keep scrolling for my breakdown of the best soft mattresses and how to pick the right one for you.

Priced at an extremely affordable rate, this mattress is a strong competitor for the battle. It is something that absolutely blew my mind if I’m honest. 

Most soft mattresses are priced higher than other mattresses because of the extra padding they require. To find a smooth, plushy and comfortable mattress at this price was like finding some hidden treasure.

Additionally, a significant feature of this mattress is its customisable firmness. Their website allows you to enter your weight in stones (1 stone is equivalent to 14 pounds) and then reveals what firmness you’ll receive.

The maximum I could adjust the bar to was 28 stones (392 pounds) which offered an incredibly soft firmness rating. The least was 6 stones (84 pounds) which offered a medium-soft firmness rating. 

I personally prefer medium-firm mattresses because of my chronic aches, but my girlfriend would find this one a perfect fit. She’s lightweight and a side sleeper, too, which is what makes her the ideal candidate for this mattress.

Heavyweight sleepers would prefer a firmer mattress so that their joints and spine is adequately supported. This Happy Beds Spring Quilted Cotton Fabric mattress is therefore not a mattress suited for them.

The rating meter is incredibly genius from Happy Beds and makes analysing so much simpler. 

When I tried this mattress out, I found the feel extremely soft and luxurious, which was definitely because of the damask fabric and satin pads layer. It had a bounce, unlike standard mattresses, which I could credit to the solid open coil springs, which my girlfriend enjoyed a lot. 

The mattress also requires regular flipping every six weeks, so this could be a bit problematic to help it maintain its softness and prevent sagging.

It is similar to most soft mattresses in durability, which means its life may not be as long as firmer mattresses. Happy Beds, however, does provide you with a 5-year guarantee for the mattress so that you can rest easy for that long, at least!

Tempur Cloud Supreme Review

Organic Luxury Hybrid Mattress with Natural Foam & New Zealand Wool.

Specification

Weight 39.72 kg
Dimensions 150 x 200 cm for King (sizes vary based on mattress choice)
Materials Tempur Memory Foam with a polyfoam support core and stretch cover fabric

Priced at a niche rate that may be unaffordable for most average users, this one is a highly luxurious buy that’s worth your pennies.

Although I was initially apprehensive of the mattress for its price, I later discovered the benefits and features that drew my attention immediately.

My girlfriend, who loves cuddling, was floored because of its cushioning and Extra Soft Material with a depth of 5 cm.

I also found that it exceeded my expectations for its support to the hips, elbows, and neck. We both are side sleepers and found this a rare feature in soft mattresses, making it quite comfortable. 

It had an exceptionally soft feel, and I found the pressure redistribution feature especially helpful for me. Given my history with back and joint aches, I didn’t expect a lot of pressure relief from a soft mattress. The Tempur Cloud Supreme mattress surprised me for sure!

I wouldn’t say it’s extraordinarily soft regarding its firmness rating, but just about so. It’s a perfect mattress for all kinds of lightweight sleepers but may be inadequate for most average weight, heavyweight and combination sleepers.

The caveat I found most annoying was its inability to keep me cool. Most soft mattresses lack this feature, and this luxurious one does too. I’m a hot sleeper and usually require a bed with airflow technology, which I thought was the only lacking feature.

Although, I really liked the hygienic and washable covers, which made me feel a little less icky about all the sweating. It’s relatively simplistic, and the polyfoam covers are easy to remove too. 

The support core and high-density memory foam were great for my spine, and I found that movement was easy too. Again, this is another feature that most soft mattresses lack and allowed my girlfriend and me to sleep without disturbing one another. 

She particularly loved the mattress’s body contouring and conforming ability because she likes being held (she’s so cute). That is because of its actively moulding and adaptive visco-elastic cells that give you perfect cushioning.

Tempur provides free delivery, returns and also a 10-year guarantee for this bed. It checks the durability criteria and makes for an excellent investment too!

If you want to make sure you’re investing in the perfect mattress, they even offer a 100-night trial period for users. 

I really enjoyed this mattress, and I’m sure you will too.

Reylon Pocket Wool Silk Cashmere Mattress Review

Organic Luxury Hybrid Mattress with Natural Foam & New Zealand Wool.

Specification

Depth 26 cm
Weight 29 kg
Dimensions 150 x 200 cm for King (sizes vary based on mattress choice)
Materials Natural layers of wool, silk and cashmere with 1390 pocket springs and breathable hand-tufted wool fabric blend. The spring density is 463 per m2 for the King size.

Reasonably priced within the midrange, I found this mattress by Reylon surprisingly ideal for lightweight sleepers. 

Its deeply incorporated wool, silk, and cashmere layers make the bed bouncier and incredible because of the knitted wool fabrics. A total stressbuster- I swear I was running my hands through the covers just for the satisfaction it gave me. 

Along with this, I also found it incredibly breathable and soft. The biggest nitpick that I have about this mattress, though, is the insulation it provides. While this may be suited for cooler weathers, a hot sweater like myself could end up in a pool of sweat every morning. 

My girlfriend was a huge fan of this one- she called it fancy, and she’s not wrong! This bed is really fancy and moderately priced too. 

The upper side of the mattress is designed such that the springs contour your body based on the pressure provided to it. The lower side, however, works on the weight distribution and makes it a comfortable sleep. 

The combination of springs is definitely a big plus point for me, and the high-density foam also prevented any sagging. That, of course, made it more supportive, durable and meant more space.

I also found that in terms of care, this mattress was simpler to handle and transport.

Like all soft mattresses, this too can deteriorate quickly if not rotated. While turning is not necessary, you may find it handy to rotate it every once in a while. 

I found this mattress soft to medium soft and think it’s ideal for lightweight sleepers of any type. Front and combination sleepers may also find it adequate provided they’re light. 

This mattress put a smile on my girlfriend’s face for sure; I hope it puts one on yours too.

Simba Hybrid Mattress Review

Organic Luxury Hybrid Mattress with Natural Foam & New Zealand Wool.

Specification

Depth 25 cm
Weight 34 kg
Dimensions 150 x 200 cm for King (sizes vary based on mattress choice)

The Simba Hybrid Mattress maybe a little heavier on your pockets and its benefits too.

I enjoyed sleeping on this mattress and found it supremely comfortable too. I credit a lot of that to the unique mattress technology they incorporated into the bed. 

Along with a cool name, the brand also offers a breathable and cooling foam layer that kept my sweats at bay. If you’re a hot sleeper like me, this is perfect for you to sleep on. 

I also specifically loved the open-cell polyfoam layer combined with the 2,500 Aerocoil titanium alloy pocket springs that make motion isolation a dream. They also made the sinking not as intense as regular soft mattresses!

While their features fit every firm and medium-firm mattresses’ checklist, the feel and texture were exactly like a soft mattress.

The zoned support layer towards the bottom is what really drew my attention. It provided my back and shoulder with great support and increased pressure distribution. I noticed that it adapted to my body rather quickly and great spine alignment too.

Besides this, I loved that the mattress did not sag or sink as much as other soft mattresses. 

The only downside of this mattress was its covers- while it is low on the heating, they’re not removable, even if you sweat a lot. It also means you can’t wash the covers and means it’ll be a little unclean. 

They recommend a mattress protector to avoid this, but that’s an additional cost to the 909 you’re already paying. 

However, in all other areas, this mattress was a true delight. I found it excellent in terms of durability, edge support, and joint support. It had a remarkable and sturdy mattress firmness with the soft and plushy feel of a soft mattress. 

It has an incredible 200-day trial and returns policy along with a 10-year guarantee too!

Brook + Wilde have perfect mattresses for heavyweight sleepers below 250 lbs within a moderate to high price range. 

They have three types of mattresses- soft, medium and firm. Their mattress guide states the scores for each of their mattresses, making it perfectly smooth and supportive. Each of these suits different preferences, and the medium-firm and firm mattresses may suit heavyweight sleepers the most.

Their Lux model is ideal for solo use and couples, too; my girlfriend and I both slept incredibly well on this mattress. She prefers a softer mattress, though, considering she’s a lightweight sleeper. 

What makes this mattress so much more worth it is its six layers of memory foam designed to provide you with the support you need. That is, again, really rare for a softer feel mattress and blew my mind away.

Their unique ‘Wave Technology’ allocated four zones that target and support your neck, shoulders, hip, and legs too. Take it from a person who bickers way too much about his aches; this really was extraordinarily pressure relieving. 

I thoroughly enjoyed this hybrid mattress that had the perfect combination of memory foam and pocket springs. I found that this was particularly very helpful for spine alignment and targeted pressure points.

Additionally, I loved this mattress for its incredibly breathable cooling technology with adequate airflow too. The cooling memory foam made my sweating much less of a hassle while correctly moulding my body.

My girlfriend loved this feature for its conforming ability and because my tossing and turning didn’t bother her during the night.

Brook + Wilde, an award-winning company, offers a 10-year warranty and guarantees you’ll sleep easier. They additionally have a free premium two-person delivery process within the UK.

Buying Guide

Features to look for in Mattresses.

Although I’ve listed out the options I think would ideally suit you, you may have a few inhibitions about them. Or maybe you just prefer a specific brand or are curious about the things to look out for.

Soft mattresses tend to be more costly than the average medium mattress, and knowing which one to invest in is essential. You don’t want to be wasting your hard-earned money on something that you won’t like either! So, to give you a thorough breakdown of what makes the best soft mattress, I’ve put together this buyer’s guide that should guide you well. That soft and plushy mattress is almost yours!

Mattress Type

There are too many mattresses out there, and also too many types of them. Each type of mattress is explicitly crafted to help provide you with the softness or firmness you prefer. While factors can influence your choices, such as sleeping style or position, it is, eventually, a matter of preferences. For an ideal soft mattress, you could choose a foam or innerspring mattress that gives you an extra bounce. You could also opt for a hybrid mattress if you want the best of both. Latex mattresses are also bouncy and sufficiently soft if that’s what you’re going for. There are many such mattresses that you could opt for. The only caveat with latex mattresses is their heating capacity. It may not be suited for hot sleepers like me! Other than that, mattress type may get influenced by the build, layers, and materials used.

Sleeping Style

Sleeping styles and positions are divided into three categories: side sleepers, such as myself, back sleepers, and front sleepers. It usually gets determined by the position or posture you hold while falling asleep comfortably. Your natural sleeping position guides the softness or firmness of the mattress that suits you. That is because different parts of your body may touch the mattress and cause pressure to the mattress. It could be your rib cage, elbows, neck or even ankles. Side sleepers don’t like a firm mattress and are more likely to develop aches in the morning with them. The ideal mattress, therefore, would be a soft to medium soft mattress. For stomach sleepers, however, a firm mattress would allow even weight distribution and adequate spinal support. Thus, it is an essential aspect to consider while shopping for a mattress that gives you the support you need for your back, neck, and joints!

Weight

In my experience, the firmness or softness of a mattress is a personal choice. While lightweight to average weight sleepers prefers softer mattresses, most average weight to heavyweight sleepers choose firmer ones. That is because it impacts how well your pressure points are supported and how well oxygen flows through your body. A combination of your sleeping style and weight can influence how you get a good night’s sleep. Softer or medium-soft mattresses have options that help with weight distribution, as I’ve gone over those above. However, it’s always ideal to go for a medium-soft to firm mattress if you’re a front sleeper or average to heavy weighted. You can check how your weight would impact the mattress's sagginess, body conformity, and adaptability before investing in it.

Durability, Materials and Temperature Control

The mattress’s durability is mainly determined by the materials used in its design. The denser the materials, the more likely they will last for a more extended period. It means that the fabric can withstand more wear and tear without sagging or indenting. Memory foam mattresses are a good choice if you want temperature regulation and soft covering in your mattress. Viscoelastic cells and gel foam with air cooling and breathable materials can help significantly with this. Innerspring mattresses and pocket spring mattresses have springs or coils that help the mattress maintain its structure and firmness. That is especially crucial if you're hunting for pressure-relieving mattresses. Firm mattresses are perfect for people who are either heavier or sleep on their stomachs and suffer from joint pain. However, you may also find appropriate softer mattresses that don't make you feel like you're sleeping on a rock!

Body Contouring, Motion Isolation and Responsiveness

Soft mattresses have the best body contouring ability. It holds you closely and warmly like an actual hug, and I think that’s beautiful. A body-contouring or adjustable mattress conforms to your body’s structure based on the pressure or weight applied to it. That can give you a feeling of true comfort and support too. However, it's essential to choose a mattress that allows movement easily too. In my experience, I've found that body contouring mattresses can sometimes make it harder to shift positions. Motion isolation which lets you and your partner have an undisturbed sleep is another feature that goes hand in hand with your mattress's contour ability. The soft padding usually achieves body contouring within the layers for that extra softness and bounce. Responsiveness refers to how fast your mattress adapts to the change in your body's movement. That, again, goes hand in hand in with motion isolation and body contouring. You're more likely to find less responsive mattresses with sifter mattresses. That could be restrictive for your movement but could be what you're looking for too.

Frequently Asked Questions

The firmness of a mattress is a personal preference and differs from person to person. However, many criteria determine how to pick the ideal mattress for you. Weight, sleeping position and mattress type are huge factors that contribute to it. 

I wouldn’t recommend soft mattresses for average weight and heavy sleepers. You should also not rely on softer mattresses if you prefer sleeping on your stomach.

Softer mattresses have a higher body contouring ability and allow sinking, which is not great for your spine’s alignment. It could affect the spine and cause it to curve abnormally. 

It can also lead to general aches and joint pains in the future.

Soft mattresses rarely have an excellent pressure-relieving or support system. I, however, being the mattress connoisseur, have found some that do. These are, of course, not highly soft but are soft enough to feel like a cloud.

It’s a thought that came to my mind earlier too! I’ve always found medium or more firm mattresses cheaper than softer mattresses, but I never knew why. Thankfully, I know now.

Soft mattresses have soft padded layering made of satin or cotton that help make the mattress softer and bouncier. These layers are often the reason why soft beds are more expensive and are absent in firmer mattresses.

Latex mattresses are also more expensive because of the materials used in their constructions.

Besides this ensuring that softer mattresses protect your spine’s alignment and pressure points adequately, soft beds need additional technology. 

Softer mattresses are also less cooling, so incorporating gel foams or cooling technology can be expensive. 

The firmness of a mattress depends on its user and your preferences. If you’re looking for a mattress that feels like a marshmallow, these options will make your hunt much more.

In a bid to find the best soft mattress UK offers for my girlfriend, a petite side sleeper, I found the map to a good night’s sleep for you too. Wasn’t that the sweetest and most handy thing I’ve ever done?

My girlfriend found her favourite one, and I hope you do too. You deserve to feel like you’re floating on a cloud with a soft and plushy bed no matter what.

With a detailed account of my experiences and guidance, I hope you got an insight into the clear winners of each category. It was a long, tedious and very dreamy experience, and I enjoyed every bit of it. 

With that, I hope you find whatever helps you sleep at night!
