1. Amerisleep AS4

In our opinion, the most comfortable soft mattress is Amerisleep’s AS4. We like Amerisleep as a brand because they make mattresses designed for types of sleepers and simplify the process of finding the right bed for you. On their website, they display who their beds are recommended for and how firm they are— this helps you narrow down your options and make a decision without feeling doubtful. They sell only five mattresses, each ranging in firmness. For example, their AS1 is their firmest mattress and recommended for back sleepers. Their AS2 is their medium-firm, AS3 medium, AS4 medium-soft, and AS5 soft. Now, you may be wondering why we chose their AS4 instead of their AS5, and we’ll get to that shortly.

Let’s talk about the layers in the AS4.

The AS4 has three layers, a comfort layer of Bio-Pur®, a support layer of HIVE®, and a sturdy base of Bio-Core®. Overall, this bed is 12 inches tall.

Bio-Pur® is plant-based memory foam, and when you lay down on the AS4, this material will mold to your body’s curves and offer instant pressure relief and comfort. The Bio-Pur® layer is 4 inches thick, which is a lot of memory foam; this thick layer gives you plenty of room to compress in the mattress and feel optimal comfort.

Below the Bio-Pur® is this bed’s zoned support system. HIVE® technology contains five comfort and support zones. In your feet, torso, and neck, this technology feels firmer and offers more support to your body, fostering a healthy spine. Around your hips and shoulders, this foam is softer to cushion these areas and alleviate pressure.

These two layers combined equal to 5 inches of comfort in the AS4. The core of the mattress is 7 inches thick, offering a stable surface for the two layers above.

The AS4 differs from the AS5 because the AS5 contains a layer none of the other Amerisleep mattresses have— a layer of latex-like foam, called Active Flex. Unlike memory foam, latex and latex-like foam are more responsive and don’t necessarily cradle your body; instead, they offer a more “lifting” feeling and keep your body suspended in the mattress. The AS5 is an excellent option for sleepers over 250 pounds looking for a soft bed, but need extra support. For sleepers that weigh between 130 and 200 pounds, this bed may actually feel firmer than the AS4, due to the responsiveness of the Active Flex material. Overall, we chose the AS4 as the softest mattress because it has 4 inches of Bio-Pur® in comparison to the AS5’s 3 inches of Bio-Pur® memory foam.

When shopping, don’t overlook sleep trials and warranties, especially when buying online. Amerisleep sells their beds primarily on their website and only just recently started opening showrooms, so they offer a 100-night sleep trial with their beds. Plus, their beds come with a 20-year warranty, protecting your investment for two decades.

2. Loom and Leaf Mattress

Loom and Leaf is a subsidiary of the well-known Saavta brand. Saavta sells three beds under three brand names: an innerspring bed called Saatva, a latex bed named Zenhaven, and their memory foam option Loom and Leaf. For sleepers seeking a soft bed, choose Saatva’s memory foam option, Loom and Leaf. We like this brand because they’ve been around for almost a decade now and have established themselves a reliable reputation, as they receive great reviews regarding both their beds and their customer service.

The Loom and Leaf mattress stands 12 inches tall, meeting our recommendation for height. Within those 12 inches, are four layers of foam.

The first layer is 2 inches of their Cooling Spinal Gel material, a memory foam infused with gel swirls. The two benefits of infusing gel into this memory foam layer include temperature regulation and extra support. The gel in this layer is strategically placed in the torso area, preventing your spine from sinking too far into the mattress. When you lay on this layer, the memory foam will contour to your body and offer some relief for pressure points.

The next layer in this bed is also memory foam but is 2.5 inches thick. The second layer of memory foam allows for deep compression in the mattress. Because the top two layers of this mattress equal to 4.5 inches in soft memory foam, this bed should most certainly feel like it’s cradling you as you sink in.

For extra support, Loom and Leaf includes a thin layer of poly-foam to keep your body suspended above the dense foam core of this bed, reinforcing the spinal gel above.

The Loom and Leaf is sold exclusively on their website, and not available in stores. Because they sell their beds online only, they offer a generous 120-night sleep trial with their beds. However, it’s important to note that the sleep trial isn’t completely free. Should you decide to return your mattress to Loom and Leaf, it’ll cost you a $99 transportation fee. This bed also comes with a 15-year warranty, protecting your bed for the duration of it’s expected lifespan.

What to Consider When Buying a Soft Mattress

Before heading to a mattress retailer or browsing online, it’s necessary to take your own sleep preferences into account to find the right bed for you. For starters, think about how you sleep at night.

Are you most comfortable on your back, stomach, or side? When you wake up in the morning, how do you feel? Are you struggling to get out of bed due to aches and pains, or are you ready to take on the day?

Even if you’re not happy with your current sleep set, that puts you one step further in your search for a new bed— you already know what you don’t like. With that knowledge, you can learn about other mattresses and how they could be a better fit for you. To touch on sleep positions, for the most part, side sleepers are best suited for soft beds because they cushion the shoulders and hips while you rest. Back and stomach sleepers aren’t necessarily not suited for a soft mattress, but they do require a bit more support.

In these next sections, we’ll be explaining the three key things to look for in a soft bed to make sure you’re buying the most suitable and comfortable option to improve your sleep.


Generally, the taller the mattress, the softer it is. The more cushioning material inside, the more cushion. All beds require a sturdy core, whether that be a pocketed coil system or a high-density poly-foam base layer. That means the layers above are responsible for providing you the plush, cloud-like feeling you want in a bed. Mattresses that are only 8 or 10 inches tall typically don’t have enough cushioning materials to create a softer sleeping surface. Whereas mattresses that are 12 inches or taller commonly provide more plushness. However, height isn’t the only thing you need to take into account. The number of layers inside the mattress matter, too.

Mattress Layers

A tall bed with numerous layers, over 4 or 5, may not feel as soft as you’d like. Though the bed is tall, each layer inside is very thin, offering less comfort. Thicker layers allow your body to sink further in the bed, giving you the more cradling feel soft mattresses provide. When searching on the internet, look for diagrams of the mattress explaining the layers inside; usually, online mattress brands offer this information on their website. These will show you how thick the layers are and what materials are used. Often, you’ll find in innerspring, hybrid, and memory foam beds alike that the top layer is foam— whether that be latex foam, poly-foam, or memory foam. Sometimes, the top layers will be cotton or wool, softer textiles. To get the best cradling feeling, choose a bed with memory foam.

Zoned Support

Soft mattresses are great for a number of sleepers; however, a big concern with them is the chance of your torso sinking too far in the bed, causing unnatural and unhealthy alignment of your spine. Over time, sleeping on a bed that doesn’t offer enough support to promote good posture can lead to chronic back problems. When buying a soft mattress, look for a bed that has zoned support or extra support in the lumbar area. Zoned support is a system of comfort and support zones in bed, designed to release pressure points and keep your spine in a neutral position. Lumbar support, on the other hand, is just extra support in the middle region of the mattress, preventing your spine from sinking uncomfortably far; this can be made with firmer foam or the inclusion of gel to make the foam more supportive.

In addition to these primary things, don’t forget to consider your body type. Firmness is subjective, and what feels soft to one person may not feel soft to you. If you’re a smaller individual and don’t weigh much, you’re going to need a very plush mattress to feel like a bed is truly soft. However, heavier individuals who carry more weight will likely feel most beds are soft. Heavier sleepers looking for more support from a mattress need to find something firm to keep their body suspended and on top of the bed.

Did You Find Your Next Bed?

When you’re looking for a plush bed, it’s crucial to find a healthy balance of cushion and support, or you could be sacrificing restful sleep. We hope this guide has helped break down the key things to look for before investing in a top-rated mattress. Remember to use online mattress reviews and free sleep trials to your advantage because they can help point you towards the right mattress for you.
