Side-by-Side Comparison of Topper Specs
Size Compatibility
Product A is designed specifically for a Queen size bed, measuring 60 inches wide by 80 inches long. Product B is sized for a Full bed, with dimensions of 54 inches wide by 74 inches long. This is a critical distinction because the toppers are not interchangeable. You must choose the model that matches your mattress dimensions exactly. Using the wrong size will leave parts of your mattress exposed or cause the topper to bunch up, disrupting sleep. Check your bed frame measurements carefully before purchasing to ensure a proper fit for your specific sleeping surface.
Thickness Profile
The two toppers differ in height, which affects how they feel on your mattress. Product A has a thickness of 3 inches, while Product B is 4 inches thick. The extra inch in Product B provides more material for pressure relief and cushioning. This additional height may make a firm mattress feel significantly softer or more supportive, depending on your preference. Product A offers a moderate lift, suitable for those who want some contouring without adding too much height to the bed. Your choice should depend on whether you prefer a deeper sink or a more stable, surface-level feel.
Firmness Options
Product A stands out with a dual-sided design that offers two firmness levels in one topper. One side is firm, and the other is extra-firm, allowing you to flip the topper to adjust the feel. Product B is listed as a single firm option. It features a memory foam layer on top and a support foam layer below, but it does not offer reversible firmness. If you are unsure about your preferred firmness level, Product A gives you the flexibility to test both sides. Product B is a straightforward choice for those who already know they want a consistent firm feel.
Cover and Attachment
Product B includes a removable cover and four corner straps to keep the topper securely in place on your mattress. This feature simplifies cleaning and ensures the topper does not shift during the night. Product A does not list a removable cover or attachment straps in its specifications. Without straps, you may need to use separate mattress anchors or a fitted sheet to keep Product A from moving. The included cover on Product B adds convenience for maintenance and stability, which is a practical advantage for daily use.
Material Density
Product A specifies the use of 38D high-density memory foam, which is noted for superior resilience and resistance to sagging. This density supports users of various weights and helps maintain the topper's shape over time. Product B lists its core material as memory foam and support foam but does not provide a specific density rating. The 38D rating in Product A gives you a concrete metric for durability and support quality. Without this data for Product B, it is harder to compare the long-term structural integrity of the foam layers directly.

Frequently asked questions
Which BedStory topper is better for back pain relief?
Both models target back pain relief through firm support. The 3-inch Queen Extra uses high-density foam for durable alignment. The 4-inch Firm Memory Foam uses a two-layer design to stabilize your bed. You should choose based on whether you need a Queen or Full size for your frame.
Is the 3-inch topper suitable for side sleepers?
The 3-inch Queen Extra is best for sleepers wanting firm support and spine alignment. It is not described as plush. The 4-inch model is explicitly recommended for back and stomach sleepers. Side sleepers might find these firm options too rigid unless they prefer minimal sink.

The BedStory 3-inch Queen Extra stands 3 inches tall. The BedStory 4-inch Firm Memory Foam is 4 inches thick. This extra inch adds more height to your bed profile. You will notice a more pronounced elevation with the 4-inch model compared to the 3-inch version.
Do these toppers come with securing straps?
The 4-inch Firm Memory Foam includes secure straps to stabilize it on your mattress. The product data for the 3-inch Queen Extra does not mention straps. You may need to purchase separate straps for the 3-inch model if you want to prevent shifting during the night.
Can I use the 4-inch topper on a Queen bed?
The 4-inch Firm Memory Foam is sized for a Full bed, measuring 54 by 74 inches. It will not fit a standard Queen bed, which is 60 by 80 inches. You should stick with the 3-inch Queen Extra if you need a topper for a Queen size frame.
Is the 3-inch topper made of memory foam?
The 3-inch Queen Extra uses high-density foam, specified as 38D density. The 4-inch model is explicitly labeled as memory foam. While both provide firm support, the materials differ. You might prefer the specific contouring of memory foam or the durable feel of high-density foam.
