Build Quality
The Gorilla Grip Silky Memory Foam Wrist Rest uses a 3-layer construction: a rubber slip-resistant base on the bottom, a memory foam core measuring 1.2 inches thick, and a soft spandex cover on top. That spandex is listed as water and stain resistant, which in practice means liquid beads rather than soaks through immediately, and a damp cloth removes most smudges without leaving residue. The full assembly weighs 0.4 lbs, which is light enough that the rubber base does real work keeping it planted - during a firm, fast typing session, the rest does not creep toward the monitor or shift sideways.
The 2-piece set includes both the keyboard rest at 17 x 3.5 inches and a mouse rest at 6 x 3.3 inches. Both pieces share the same 3-layer build and rubber base. No peeling, delamination, or color-bleed issues appear in 2026 product listings, and the design has remained consistent since prior model years, suggesting Gorilla Grip has not made material changes to the construction. Gorilla Grip publishes a support email (hello@gorillagrip.com) for warranty claims, which is more than most sub-$20 accessories provide.
One honest concern: Gorilla Grip does not publish foam density in kilograms per cubic meter, which is the standard measure for predicting long-term durability in memory foam. Without that number, there is no way to verify how the foam holds up after 12-18 months of daily compression. Generic memory foam rests in this price range often show visible flattening within a year.
Comfort & Ergonomics
The 1.2-inch height is the product's single strongest selling point. Most budget wrist rests in the $10-15 range measure closer to 0.75-0.9 inches, which provides minimal elevation. Gorilla Grip's extra thickness meaningfully reduces wrist extension angle for average-height adults using standard 28-30 inch desks. The slow-rebound foam distributes pressure across the wrist rather than creating a hard pressure point at the carpal tunnel area.
That said, ergonomics are body-specific. The fixed 1.2-inch height is ideal for users whose keyboard surface sits roughly at elbow height. Users with higher-set desks or thicker keyboards (keycap height above 10mm) may find the rest positions their wrists at an upward angle, which increases rather than decreases strain. There is no adjustment mechanism to correct for this.
The spandex surface is genuinely smooth and does not create friction burn during long typing sessions, which cheaper cloth-top rests sometimes do.
Adjustability
There is none. The Gorilla Grip ships at one fixed height, one fixed width, and one fixed length. No height inserts, no angle wedges, no secondary sizing options exist in the product line as of 2026. If 1.2 inches does not match your wrist anatomy and desk setup, this product will not work for you regardless of price.
ErgoFoam ($25-35) provides adjustable height inserts that let buyers customize elevation in 0.5-inch increments. For buyers with non-standard ergonomic needs, that $10-20 premium is functionally mandatory.
Assembly
There is no assembly. The keyboard and mouse rests arrive ready to place on your desk. Positioning takes under 60 seconds. The rubber base adheres to desk surfaces through friction alone - no adhesive, no screws, no brackets. Removing and repositioning the rest does not leave residue.
Value for Money
At $15.99 from Walmart (the lowest confirmed 2026 street price), this is one of the cheapest 3-layer memory foam wrist rests from a named brand available in the US market. Gimars Upgrade Enlarge Silky Gel Memory Foam runs approximately $20 for a comparable gel-foam hybrid. Generic AliExpress variants cost $15-25 but carry no warranty support and unverifiable foam quality.
For a buyer who fits the product's fixed geometry, $16 for a 1.2-inch, slip-resistant, water-resistant wrist rest is a reasonable spend. For anyone who might need adjustability or who types more than 6 hours daily and wants proven foam longevity, spending $25-35 on ErgoFoam is the more defensible long-term purchase.
