Our Experience with the PlushBeds Natural Latex Topper
The Natural Latex Topper by Plushbeds is certainly one of the firmest and most eco-friendly toppers on the market. Made of 100% pure Talalay latex, this organic topper gives you a floating sensation and relaxing pressure point relief. It also features an open-cell foam design that offers contouring and promotes airflow within the topper. Additionally, this product sets itself apart from other models by letting you choose between two thickness options and four different firmness levels, depending on your specific needs and preferences. With firmness options ranging from Soft, all the way to Extra Firm, the Plushbeds Latex Topper is suitable for all sleeper types, regardless of their body weight.
First of all, I want to point out that you can choose between a 2″ and 3″ thick toppers depending on your thickness preference. We recommend either the Soft or the Medium versions for side sleepers because they offer the most cushioning and pressure relief. The Soft option is better suited for lighter individuals and the Medium version is recommended for average weight side sleepers. On the other hand, back and stomach sleepers require a more supportive sleeping surface to ensure a neutral spinal alignment. Therefore, they should opt for either the Medium-Firm or the Extra-Firm mattress topper to make their mattress firmer and more responsive.
This premium mattress topper is made of 100% pure Talalay latex, which is a buoyant material that distributes weight over a wider area than memory foam or polyfoam. Derived from the sap of rubber trees, natural latex is hypoallergenic, antimicrobial, and resistant to dust mites and mildew, which makes this topper a great choice for allergy sufferers. Hot sleepers will also enjoy how cool this topper sleeps due to its open-cell latex foam structure. The only downside of this topper is that it has high motion transfer, which might be a deal breaker for people who sleep with a restless partner or a pet. Overall, this product is outstanding in many aspects especially if you’re looking for a premium firm mattress topper.

Our Experience with the Amerisleep Lift Topper
Manufactured by one of the best bed-in-the-box companies in the U.S. , the Lift Mattress Topper features Amerisleep’s premium proprietary materials and technology. The Lift topper’s unique open-cell memory foam has all the benefits of traditional memory foam but none of its drawbacks. It offers amazing pressure relief and provides you with a breathable sleep surface for maximum comfort. This model is eco-friendly and is available in two firmness options: Comfort Lift and Support Lift, making it a versatile choice for most sleepers. Today, our review will be focused on the Support Lift version by Amerisleep as it is one of the best firm mattress toppers on the market.
The Support Lift topper is most suitable for back and stomach sleepers who need the reinforced support for maintaining a healthy spinal alignment. This version of the Lift topper is quite responsive, so you’ll feel like you’re floating on top of it rather than sinking into its layers. Combination sleepers will love how easy it is to move around and switch positions on this topper. And if you sleep hot, this topper’s open-cell foam promotes airflow and helps you stay cool throughout the night. The Support Lift might be too firm for some side sleepers, especially those who weigh below 130 lbs, in which case the Comfort Lift version would be better.
The Lift Mattress Topper is 3″ tall and both of its versions are made of slightly different proprietary foams. The Comfort Lift is made with Bio-Pur Foam which has an open-cell structure and provides sleepers with extra cushioning and pressure relief. While the Support Lift is made using another proprietary material called Affinity Foam, which has reinforced support and gives you a firmer sleeping surface. Basically, you should choose the Comfort Lift if you prefer more pressure relief and sinkage. And you should opt for the Support Lift if you need a topper that can support your spine and keep it in a neutral alignment.

The Avocado Vegan Mattress Topper is made entirely out of sustainable materials such as organic latex and cotton to provide sleepers with great comfort and relaxing pressure relief. It’s offered in two firmness levels: Plush, and Firm, to accommodate all sleeper types regardless of their body type.

Today, we will be focusing on the Firm option and how it can help you get the best night’s sleep.
The Firm version of the Avocado Vegan Topper works best for back and stomach sleepers who require a more supportive surface for their spine and hips. The topper’s latex construction also makes it quite bouncy and responsive which is a great quality for combination sleepers who frequently switch sleeping positions. However, if you’re side sleeper and you want to try out this topper, we suggest that you go for the Plush option. The right topper for you is one that provides nice cushioning to relieve pressure points and contouring for your body’s curves. And unlike traditional memory foam, this latex topper does not trap body heat, so you don’t have to worry about sleeping hot.

Choosing the best firm mattress topper
These are the main factors that you should consider when selecting the best firm mattress topper:
Material – Mattress toppers are commonly made using memory foam, latex, or polyester blends. Some models are made of unique proprietary materials, such as the Airweave’s Airfiber technology. Each of these materials has its own pros and cons, and you should choose the one that’s best suited to your needs.
Thickness – Generally, thicker toppers can alter a bed’s feel to a greater extent than thinner toppers. Thicker toppers also tend to be more expensive, but this is not always the case as one of the most expensive mattress topper’s on the market, the Airweave Top Mattress, is only 2″ thick.
Body weight – Most people looking for firm mattress toppers are usually back and stomach sleepers. Assuming that you are one these individuals, you should opt for a topper that can accommodate your weight and give you the support that you need to sleep comfortably.
Durability and Price – Lastly, you should look for a mattress topper that has great value for money. The best firm mattress toppers are highly durable and are made with premium materials for the best results.
Potential pros and cons of firm mattress toppers
Pros:
- Extra support – Firm toppers are great for back and stomach sleepers who need a firm sleeping surface to promote a neutral spinal alignment. A firm topper can also aid in pain relief, especially those who suffer from back pain.
- Prolongs the lifespan of your mattress – A firm mattress topper can increase a bed’s longevity by reducing pressure on the springs, delaying sagging, and mitigating general wear and tear of the mattress.
- Adds responsiveness – If you find yourself struggling to move around your mattress because you feel overly stuck, then you should try putting a firm topper or mattress pad on top of it to prevent excessive sinkage and increase the bed’s buoyancy. This tends to result in easier movement when you’re trying to switch from sleeping position to another.
Cons:
- Not suitable for side sleepers – A firm mattress topper does not have that much give to cushion a side sleepers sensitive joints. If you sleep on your side, you should opt for a softer topper, preferably one that’s made with gel-infused memory foam.
- Not suitable for some lightweight sleepers – Some individuals who weigh below 130lbs would be more comfortable sleeping on a mattress topper that has a medium-soft to medium-firm feel.
