15–18.5-Inch Ledge Riser for Signature Chaise Deep

If the ledge is deeper than your Signature Chaise Deep supports on its own, the right riser may let you keep the seat you enjoy. This riser is the 15–18.5-inch configuration for one Chaise Deep. Check the water where the chaise will actually sit before choosing it.

This is a fit-specific adapter for one standard Signature Chaise Deep. The Backyard Solstice offer on this page is only for water measuring more than 15 inches and no more than 18.5 inches at the exact placement location.

Is This the Right Riser?

• Choose it when: the finished water depth is greater than 15 inches and no more than 18.5 inches where the Chaise Deep will sit.
• Do not choose it at 15 inches or less: the Signature Chaise Deep is designed for that range without this riser.
• Do not choose it over 18.5 inches: this configuration is not intended for deeper water.
• Do not choose it for: the standard Signature Chaise, Adjustable Reclining Chaise, Signature Chair, Signature Lowback Chair or any Autograph product.

Measure Before Ordering

Measure from the finished ledge surface to the waterline at the exact place the Chaise Deep will stand, with the pool at its normal operating level. Check more than one point across the full placement area.

Pause before ordering if the ledge slopes, the readings vary across the footprint, the normal water level crosses the 15- or 18.5-inch boundary, or your measurement sits exactly on a boundary you are unsure about. The riser changes the Chaise Deep's relationship to the water, but it does not correct an uneven, undersized or unsuitable ledge. Use our tanning-ledge measurement guide or send the measurements through Personal Product Guidance.

What the Riser Changes

The riser raises the Chaise Deep so it does not sit as low in deeper water. This can reduce the amount of water around the seat and help preserve the intended fixed-recline experience. The result still depends on the exact depth, normal water-level variation and where the chaise is positioned.

The riser does not make the Chaise Deep upright or adjustable. If you want a chair-like posture or movable back positions, choose the appropriate seating product rather than using a riser to imitate a different one.

What Is Included

• One Signature Chaise Deep Riser assembly for one Signature Chaise Deep
• Your selected resin color: Gray, Cloud or White

Not included: Signature Chaise Deep, cushion, pillow, shade, table, tools not specified by the assembly instructions or any other accessory. Product photography may show seating and accessories for context.

Dimensions, Setup and Ownership

• 26.5 inches long × 21.5 inches wide × 11.5 inches high
• 12 lb before installation
• Five-step assembly required

Follow the supplied setup instructions and confirm that the Chaise Deep is seated correctly in the riser before use. Do not stack risers, add improvised blocks or combine this adapter with another furniture family.

The UV-stabilized resin is designed for pool environments and is compatible with all pool types, including vinyl. Choose the color deliberately when matching an older Chaise Deep whose finish has experienced years of sun and water exposure. For routine care, rinse with water and clean gently with a soft cloth or soft-bristle brush and mild soap. Avoid abrasive tools.

Timing, Warranty and Returns

See the selected option’s estimated ship-out time beside Add to cart. Delivery transit is additional. Timing and availability can change by color and order date, and a delivery date is not guaranteed. Backyard Solstice confirms current availability after the order is placed.

The manufacturer provides a 15-year residential and 10-year commercial warranty against covered material defects. Review the warranty terms for exclusions and claim requirements.

Because this is a made-to-order, compatibility-specific product, confirm the depth and chaise model before ordering. Eligible returns require prior authorization and must meet the condition, packaging and timing requirements in our Return & Refund Policy. Return shipping and a restocking fee may apply. Shipping eligibility and service details are governed by our Shipping Policy.

Still Deciding?

If your ledge is deeper than 18.5 inches, varies across the placement area or does not clearly fit this depth range, do not guess. Send us the exact water-depth readings, a photo of the ledge and the name of the chaise you own through Personal Product Guidance. The correct answer may be a different supported configuration—or no current Backyard Solstice configuration at all.
