Mattress Topper - 4 Inch - Breathable Memory Foam - Select High Density by Viscosoft Queen

A: Hi Aly! Great question — the Select High Density topper actually has a medium-firm feel, so if medium is already too firm for you, this one likely isn't the best fit. It's designed to add firmness and support, not softness. For a plush feel, we'd suggest two options depending on your budget: Dusk Mattress Topper — medium-soft gel-infused memory foam, available in 2" or 3", great value starting at $72.95. Hybrid Lux Mattress Topper — dual-layer memory foam with a pillow top and Tencel cover for that extra cloud-like feel, currently on sale, starting at $149.95. Kind regards, Taisiya Viscosoft Support

A: Hello KZ, Thank you for your question. The memory foam inside the topper is light blue in color. The removable cover is white on the top and sides, with a dark blue bottom panel. So, the topper is not entirely blue. Kind regards, Taisiya Viscosoft Support

A: Hello Abuelita2, and thank you for your question. You can use the Viscosoft topper on top of your existing one, and it will likely help soften your firm mattress. The high-density foam is designed to contour to your body and relieve pressure points that a firm surface can aggravate. However, keep these points in mind: Stability: Stacking toppers can cause them to shift. Use the adjustable straps on the Viscosoft to secure both layers to the mattress. Support: If your current topper is already soft or sagging, adding another layer on top may cause you to sink too deep, which can lead to back alignment issues. Sheet Fit: Multiple layers will significantly increase the height of your bed, so you may need extra-deep pocket sheets. For the best results, place the firmer topper on the bottom and the Viscosoft on top. If your current topper is worn out, you may find better support by replacing it entirely rather than stacking. Kind regards, Taisiya Viscosoft Support

A: Hello Alison, Yes, a 3” topper can work on a 4” mattress and would bring your total height to approximately 7”, which fits within your travel trailer requirement. We recommend double-checking your mattress dimensions to ensure the topper fits properly, as RV and trailer beds often differ slightly from standard sizes. We do offer RV-friendly options such as Queen Short (74” x 59”) and King Short (74” x 71”), which are commonly used in travel trailers. Choosing the correct size will help prevent overhang or shifting and ensure the best comfort and fit. Please let us know if you’d like help selecting the right size. Kind regards, Taisiya ViscoSoft Support

A: Hello Sleeplover, You can place the topper on your mattress or any flat surface right away. However, we recommend allowing up to 48 hours for it to fully expand, as it arrives vacuum-packed. Some may expand faster, but giving it 1–2 days helps ensure the best comfort and support. Kind regards, Taisiya ViscoSoft Support

A: Hello Jspringator, We do not recommend trimming the topper, as cutting the foam can affect its performance and durability. Instead, we offer special RV-friendly sizes designed for smaller spaces: Queen Short: 74" L x 59" W (available in 2", 3", and 4") King Short: 74" L x 71" W (available in 3" only) These sizes are commonly used in campers and RVs and should be a much better fit. Kind regards, Taisiya ViscoSoft Support

A: Hello Robin, And that's a great question. All our Toppers are CertiPur certified. There are no harmful chemicals, formaldehyde, VOCs, or fiberglass and no fire retardant used on the Topper. It is tested constantly in our factory for quality assurance. If the Topper does not meet a quality standard, it is unable to be distributed. This certification ensures the foam meets strict standards for content, emissions, and durability, making it safe for everyday household use, including on a child’s bed. Kind regards, Taisiya Viscosoft Support

A: Hello Curious! Thank you for your question. None of our products contain fiberglass. I hope this helps. Kind regards, Taisiya Viscosoft Support

A: Hello Peggy. Thank you for your question. Yes, the ViscoSoft Select High Density memory foam topper is compatible with adjustable bases. The flexible memory foam bends smoothly with head and foot adjustments without affecting performance or durability. Kind regards, Taisiya, Viscosoft Support

A: Hello Kris, Thank you for your question. These toppers use high-density memory foam, approximately 3.0 lb/ft³. This density range is designed to balance pressure relief, durability, and breathability, providing consistent support without feeling overly firm.
