Mattress Topper - 3 Inch - Breathable Memory Foam - Select High Density by Viscosoft Short Queen

A: Hello AM, The weight of our High Density Twin XL 3'' topper is 20.35 lbs. Let me know if you have any other questions. Kind regards, Taisiya Viscosoft Support

A: Hello Da, Great question! The short answer is yes — but the key is picking the right type of topper. Here's what Viscosoft's own sleep experts say about this exact situation: Why your mattress is causing back pain: When a mattress is too soft, your hips sink lower than your shoulders, causing your spine to curve unnaturally (sometimes called "hammocking"). That's the root cause of the lower back pain. Will the Select High Density topper help? Yes, this is actually one of the best choices for this problem. Because the foam is denser than standard toppers (3.5 lb density), it creates a firm, supportive layer on top of your soft mattress rather than sinking into it. The 3-inch thickness is the sweet spot — it's enough material to form an independent support layer that helps realign your spine. The 2-inch may not be quite enough to mask what's underneath, while the 4-inch is better suited for larger-framed sleepers. What about the Active Cooling topper? This is also a solid option, and it actually solves two problems at once. Soft mattresses tend to sleep hot because you sink into them and trap body heat. The Active Cooling topper gives you 4 inches of supportive foam (enough to correct the sinking feeling) plus copper-infused memory foam that actively draws heat away from your body. If you run warm at night, this one is worth the consideration. One important caveat: If your mattress has a permanent physical dip or divot (from worn-out springs or collapsed foam), a topper will eventually follow that shape. A topper works best when the mattress is structurally sound but just feels too soft for your preference. You can do a quick "elbow test" — press your elbow into the center of the mattress and lean your weight in. If it sinks more than about 2 inches and takes a long time to spring back, a topper should help significantly. To summarize the two best options for your situation: Select High Density (3") — best for firmer support and back/hip pain relief, medium-firm feel Active Cooling Copper (4") — best if you also sleep hot; slightly more cushion with equal or better support depth Kind regards, Taisiya Viscosoft Support

A: Hello! Thank you for your question. Yes, the ViscoSoft Select High Density Mattress Topper can absolutely make a noticeable difference on a medium firm mattress — it just depends on what you're looking for. If your medium firm mattress is giving you a solid foundation but you'd like a bit more cushioning and pressure relief on top, this topper is a great solution. The high-density memory foam conforms to your body to relieve pressure points while still providing support underneath. Here's a quick guide on thickness: 2" – A subtle softening effect; great if you mostly like your mattress and just want a touch more comfort 3" – Our most popular choice; noticeably softer feel without sacrificing support — ideal for medium firm mattresses 4" – Maximum plushness; transforms a firm sleep surface into something much more cushioned Many of our customers with medium firm mattresses go with the 3" option and love the result. Kind regards, Taisiya Viscosoft Support

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.

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.
