Mattress Topper - 3 Inch - CertiPUR-US Certified Gel Memory Foam - Hybrid Lux Dual Layer by Viscosoft Twin

A: If the sponge is to big can I cut it?

A: Hello Shirley, Thank you for your question. Our 4-inch Hybrid Lux Dual Layer includes 3 inches of memory foam and 1.5 inches of ultra-plush, Eco Origin fiberfill in the cover. The actual foam piece is 3 inches thick. Should you have any other questions, do not hesitate to contact our support team. Best regards, Taisiya ViscoSoft Support support@viscosoft.com (844) 888-4726

A: Thank you for your question, Molly! “Breathable” generally means the materials allow air to circulate, which may help reduce heat buildup. The Hybrid Lux combines gel-infused memory foam with a quilted pillow-top cover made with breathable TENCEL™ fibers, offering contouring support and a soft, cushioned feel. Kind regards, Taisiya ViscoSoft Support

A: Hello Rosalie, Thank you for your question. The topper does not have a cutout area. The image uses a cutaway view for illustration purposes to show the topper’s two layers: the memory foam layer and the quilted pillow-top cover. In actual use, the cover completely encloses the foam and covers the surface of your mattress. We hope this helps! Kind regards, Taisiya Viscosoft Support

A: Thank you for your question! While we’re unfortunately unable to disclose the ILD rating, the memory foam in our 4-inch Hybrid Lux Mattress Topper has an average density of 2.5 lb/ft³. Kind regards, Taisiya ViscoSoft Support

A: Hello Ntweety, Our Hybrid Lux topper is a great option for adding cushioning and pressure relief to a super-firm dorm mattress. However, a Queen Short topper may not fit a Full-size dorm bed correctly. Please measure your dorm mattress’s length and width, then compare the measurements with the size guide in the product listing before ordering. Kind regards, Taisiya ViscoSoft Support

A: Hi Krystal, yes—the plush pillow-top layer is approximately 1.5" thick on both the 3" and 4" Hybrid Luxe models. The difference is in the memory-foam base: the 4" model has a thicker foam layer for additional support and cushioning. Kind regards, Taisiya ViscoSoft Support

A: Hello Barbara, Thank you for your question! The sheet depth you need depends on the combined height of your mattress and topper. Please add your mattress thickness to the topper thickness you select, then choose fitted sheets with pockets deep enough for that total. For example, a 12" mattress with the 4" Hybrid Lux topper will generally need sheets with at least 16" deep pockets. The Hybrid Lux cover itself has an 18" elastic skirt to secure it around the mattress. For the most comfortable sleep, we recommend breathable cotton, TENCEL™, bamboo, or linen sheets. These materials help airflow and moisture-wicking, while microfiber or polyester sheets can hold in more warmth. Kind regards, Taisiya Viscosoft Support

A: Hello Nancy, Thank you for your question! Yes, our Hybrid Lux Mattress Topper can be a great option for a sleeper sofa with a thin mattress. The combination of gel memory foam and the plush pillow-top cover helps add cushioning and pressure relief, making a thin sleeper mattress much more comfortable. The foam is also CertiPUR-US certified, and the removable cover is machine washable for easy care. One thing to keep in mind is that if you have a pull-out sleeper sofa, you'll most likely need to remove the topper before folding the bed back into the sofa, as a 3" or 4" topper typically won't fit inside the sofa when it is closed. If you're comfortable storing the topper separately during the day, it should work very well. If you could let us know whether you're considering the 3" or 4" version—or even the make and model of your sleeper sofa—we'd be happy to recommend the best option for your setup. Kind regards, ViscoSoft Support

A: Hello, Thank you for your question. Yes, the mattress topper is made with CertiPUR-US® certified memory foam and is latex-free. The foam is made without fiberglass, formaldehyde, ozone depleters, or harmful flame retardants, and it has low VOC emissions for indoor air quality. While no bedding product can be guaranteed to be completely allergy-free for every individual, the materials used are designed to be safe and suitable for most sleepers, including those with sensitivities. Please let us know if you have any other questions. Kind regards, Taisiya ViscoSoft Support

A: Yes, our Hybrid Lux Mattress Topper is compatible with most adjustable bases. The memory foam is flexible enough to contour with the movement of the bed as the head and foot sections are adjusted. For the best experience, we recommend ensuring the topper is properly secured to the mattress using the elastic corner straps and fitted cover included with the topper.
