Every outdoor wedding photo shows the same quiet problem if you look closely: a chair leaning slightly, a row dipped into the lawn, a guest rocking on the legs. It happens because a seated adult's weight lands on four small points, and soft ground gives way under small points. This guide explains what each surface does to chairs, which of ours cope, and how to fix soft ground with cheap, simple steps. It applies to lawns in the Chicago suburbs, forest preserves, lakefront spots and backyards alike.

What each surface does

Three ground types and what happens to chair legs on each Three side views of a chair leg. On dry grass, the leg sits on top with little sinking. On wet grass or sand, the leg sinks and the chair tilts. On gravel, the leg rests on loose stones and the chair rocks. A plywood sheet under any of them keeps the chair level. Dry grass Wet grass, sand Gravel Usually fine Sinks, tilts Shifts, rocks A plywood or flooring layer fixes all three
Chair legs fail differently on each surface: they sink in wet ground and shift on loose stone.
  • Dry, firm grass. Most outdoor-friendly chairs sit fine for a ceremony. Mowed, level lawns do best.
  • Wet grass. Soil softens quickly in spring and after rain. Legs sink and chairs tilt back.
  • Sand. Legs sink unevenly, and sand works into joints and hinges. It is hard on folding chairs.
  • Gravel. Chairs wobble because legs rest on loose stone, and slim legs can shift when someone sits.

Which chairs cope

Our catalog marks seven chairs as outdoor-friendly: cross-back, ghost, rattan, infinity, shell, Windsor and the garden folding chair. Outdoor-friendly means the material tolerates the weather, not that every ground works.

Chair On firm grass On soft ground Note
Garden folding Good Needs flooring Slats and light weight
Cross-back Good Needs flooring Wood legs sink when wet
Windsor Good Needs flooring Wide stance helps a little
Shell Good Needs flooring Light, stackable
Infinity Fair Avoid Slim metal legs
Ghost Fair Avoid Slim legs, scratches
Rattan Fair Needs flooring Weave should stay dry

If you need a ceremony on soft turf, a flooring layer is better than switching chairs. If you cannot add flooring, choose the garden folding or the cross-back, which are the sturdiest stackable options. See garden folding vs white plastic chairs for how the folding chair handles it.

Fixes that work

  1. Plywood strips. Sheets of plywood under each row keep legs from sinking. They can be hidden with a runner or leaves.
  2. Interlocking flooring. Panels of plastic or wood form a firm base for rows or a whole tent.
  3. Chair pads or feet. Flat disc feet spread the weight on soft ground. Ask if your rental company can supply them.
  4. Aisle runner. A simple fabric runner doesn't fix the ground, but protects the aisle itself.
  5. Tent flooring. If you rent a tent, floor it. Ask the tent company about subfloors for uneven or soft ground.

Chicago-area notes

Spring rain and thaw can leave Chicago-area lawns soft for days. Lakefront and beach spots add sand and wind. If your ceremony is at a park, a forest preserve or a beach, check with the park district or forest preserve district that manages it about permits, vehicle access and what can be set up. Rules differ by location, so ask the managing agency before you plan. Our guide to outdoor event chairs and Chicago weather covers wind and temperature, and ceremony vs reception chairs helps you split chairs by surface.

For fall and early spring ceremonies, leaves, damp ground and low temperatures also make a base layer sensible. A dry plywood strip is both a safety measure and a way to keep dresses clean.

Frequently asked questions

Can I put chairs on grass?

Yes, on firm, dry, level grass. On wet or soft grass, put plywood or flooring under the rows to stop the legs sinking.

What is the best chair for sand?

None are ideal. If you must use sand, choose a light chair like the garden folding and set it on flooring or a firm path. Sand works into hinges and joints, so ask about cleaning.

Do chairs work on gravel?

Poorly. The legs rock on loose stone. Use flooring or move seating to a hard surface.

How do I stop chair legs sinking?

Place plywood strips or flooring under the rows, or use flat chair feet. Test with a person sitting before you finish the setup.

Are ghost chairs okay on grass?

Only on firm, dry grass. Their slim legs sink on soft ground, and the acrylic scratches on gravel.

Do I need a permit for an outdoor ceremony?

It depends on the location. Parks, beaches and forest preserves have their own rules, so ask the managing park district or forest preserve before you order.

Will the rental company set up chairs on a lawn?

Setup is quoted by location and conditions, so describe the ground when you request a quote.
