How these alternatives compare
BedStory 3 Inch Queen Firm Mattress Topper
The BedStory Queen Firm Topper offers a dual-firmness design, allowing you to customize support levels by flipping the cover. This is a practical difference from the Glendan, which provides a single firm feel. Both models share a three-inch thickness and a removable, machine-washable cover. However, the BedStory is limited to Queen size, while the Glendan fits the larger California King frame. You should pick the BedStory if you want adjustable firmness on a standard Queen bed. Choose the Glendan if you need the extra length and width of a California King with consistent, firm support throughout the night.
BedStory 3-Inch Firm Full Memory Foam Topper
The BedStory Full Firm Topper uses a two-layer foam construction to deliver targeted pressure relief for back and stomach sleepers. Like the Glendan, it features a firm profile and a machine-washable cover. The key difference is size; this model is designed for Full beds, measuring 54 by 74 inches. The Glendan is significantly larger at 72 by 84 inches. If you sleep on a Full-sized bed, this BedStory option provides similar firm support and easy maintenance. If you require a California King footprint, the Glendan remains the better choice for its ergonomic five-zone design and larger surface area.
Glendan Full-XL Firm Mattress Topper
The Glendan Full-XL Firm Topper mirrors the original California King model in design, featuring a three-inch bamboo charcoal foam layer and a five-zone ergonomic structure. Both share the same firm feel, removable cover, and safety certifications. The primary distinction is the bed size. The Full-XL version measures 54 by 80 inches, fitting a Full XL mattress. The original California King topper measures 72 by 84 inches. You should select the Full-XL model if your bed frame is smaller. Select the original Glendan if you need the extended length and width for a California King bed while maintaining identical support characteristics.
ViscoSoft 3-Inch High Density Mattress Topper
The ViscoSoft High Density Topper uses gel-infused memory foam to prioritize cooling and spinal alignment. It shares the three-inch thickness and firm feel of the Glendan. However, it is designed for Twin beds, measuring 38 by 74 inches. The Glendan is much larger at 72 by 84 inches. The ViscoSoft also weighs 19 pounds, indicating a dense build. You should choose the ViscoSoft if you need a firm, cooling topper for a Twin bed. Pick the Glendan if you require a California King size with a five-zone ergonomic design for precise weight distribution and pressure relief across a larger surface.
BedStory 3 Inch Firm Queen Mattress Topper
The BedStory Queen Firm Grey Topper offers a firm, three-inch profile similar to the Glendan. It includes adjustable comfort features and focuses on stability and cooling. Both models are firm and suitable for back or stomach sleepers. The main difference is size and color. The BedStory is a Queen size, measuring 60 by 80 inches, and comes in Grey. The Glendan is a California King size, measuring 72 by 84 inches, and is White. Choose the BedStory if you need a Queen size with adjustable comfort. Choose the Glendan if you require the larger California King dimensions and a specific five-zone ergonomic design.
BDEUS Dual Layer 5-Inch King Mattress Topper
The BDEUS Dual Layer King Topper offers a plush, five-inch profile with a quilted pillow top and down alternative fill. This contrasts sharply with the Glendan’s firm, three-inch foam construction. The BDEUS measures 78 by 80 inches, fitting a standard King bed, while the Glendan fits a California King at 72 by 84 inches. The BDEUS prioritizes softness and temperature adjustment via cooling gel. The Glendan prioritizes firm support and spinal alignment. You should pick the BDEUS if you prefer a plush, soft surface. Choose the Glendan if you need a firm, supportive surface for pain relief on a California King bed.
