Side-by-Side Hybrid Mattress Comparison
Firmness level
The VISCOFLEX 14 Inch Full Hybrid is labeled as Medium Firm in its key specs, while the VISCOFLEX Extra Firm Queen Hybrid is listed as Extra Firm. This distinction matters for support preferences. You may find the Full size model offers a slightly softer feel suitable for side sleepers who need pressure relief on shoulders and hips. The Queen model targets those who prefer a sturdier surface for back support. Both use pocketed coils, but the firmness rating changes how you sink into the mattress. Choose the Medium Firm option if you want balanced cushioning. Select the Extra Firm version if you need rigid lumbar support.
Mattress construction
Both models utilize a hybrid design combining pocket springs and foam layers. The Full size specifies a cooling gel comfort foam layer, while the Queen model mentions premium foam layers without specifying the gel component in its key specs. However, the attributes for the Queen model also list Cooling Gel as the cover material. Both constructions aim to promote airflow through open structures. The pocketed coils in each mattress are designed to absorb motion, isolating movement so you do not feel your partner shift. This shared coil-and-foam approach ensures similar breathability and durability for both sleepers.
Size and dimensions
The primary physical difference is the size. The Full model measures 54 inches wide by 74 inches long. The Queen model is wider at 60 inches and longer at 80 inches. This provides 6 inches of extra width and 6 inches of extra length for the Queen. If you share the bed, the Queen offers more personal space. The Full size is better for single sleepers or smaller rooms. Both share the same 14-inch height. The Queen model is heavier due to the larger surface area, though exact weights are not provided for both. You must choose based on your room dimensions and sleeping arrangement.
Certification and safety
Both mattresses meet strict safety standards with CertiPUR-US and OEKO-TEX certifications. They are both fiberglass-free and feature ultra-low VOCs to ensure safe breathing. The product data confirms that neither model contains harmful chemicals or off-gassing agents. This makes both options safe for families and those with chemical sensitivities. The certifications apply to the foam components in both the Full and Queen sizes. You can trust that both models adhere to the same quality and health guidelines. This shared commitment to certified materials ensures peace of mind regardless of which size you select.
Special features
Both models are offered as a Bed in a Box, meaning they arrive compressed and rolled for easier delivery. The Full size attributes explicitly list this special feature. The Queen model does not explicitly state this in its attributes, but the shared construction and brand practices imply similar packaging. Both feature cooling gel elements for temperature regulation. The pocketed coil systems in both models provide motion isolation, absorbing 83% of movement. These shared features ensure that you get a convenient setup and a quiet sleep environment with either choice. The difference remains strictly in the size and firmness rating.
Which viscoflex mattress suits you
Side sleepers needing pressure relief
The Full model is labeled Medium Firm. This softer feel cushions shoulders and hips better than the Extra Firm option. You get targeted support from pocketed coils without excessive hardness. The 14-inch height provides ample comfort layers. This setup helps maintain spinal alignment while reducing pressure points for side sleepers.
Back sleepers wanting firm support
The Queen model is Extra Firm. This higher firmness level offers enhanced lumbar support for back sleepers. The 14-inch hybrid construction keeps your spine neutral. You get responsive pocketed coils that adapt to your curves. The extra firmness prevents sinking, ensuring you wake up with balanced comfort and less stiffness.
Couples prioritizing motion isolation
Both models absorb 83% of motion. The Full size offers a slightly narrower sleep zone. This can feel more contained for some couples. The pocketed coils work independently to isolate movement. You will experience undisturbed sleep regardless of which size you choose, as both share this advanced spring design technology.

Does the cooling gel cover help with temperature regulation?
Both mattresses feature a cooling gel cover material designed to help manage heat. This feature assists in dissipating body warmth during the night, promoting a cooler sleep environment.
