Euro Gusset Upgrade for Sterling Mattresses

Euro Gusset Upgrade — Add a 3" Comfort Layer Compartment to Your Sterling Mattress

The Euro Gusset is a zip-on fabric compartment that attaches to the top of your existing Sterling mattress, adding a 3" space to house interchangeable comfort layers. It’s the easiest way to upgrade your current bed to a Euro Top configuration without replacing the entire mattress.

Note: Comfort layers (3" latex or memory foam) are not included and must be purchased separately. Two 1/2-sheet comfort layers are required to fill the gusset on Queen, King, and Cal King sizes.

Compatible Comfort Layers (Sold Separately)

• 3" Natural Talalay Latex Topper — Soft (19–22 ILD) or Firm (34–38 ILD)
• 3" Plush Memory Foam Topper — 5 lb. density

Mix and match — choose a different option for each side of the bed to customize comfort per sleeper.

Compatible With

• Sterling Imperial Series mattresses
• Sterling Silver Lining Series mattresses
• Sterling Softside Waterbed cover systems (8300, 8400 & 8500 series)

How It Works

1. Unzip your current mattress top cover
2. Zip on the Euro Gusset in its place
3. Insert your choice of 3" comfort layers — one per side

Why Upgrade to a Euro Top?

• Customize each side of the bed independently — different firmness per sleeper
• Swap or replace comfort layers as your preferences change — no need to buy a new mattress
• Adds a more traditional mattress feel on top of your waterbed or innerspring system
• Extends the life of your existing Sterling mattress
