7 tips for building a gravel patio as a seating area

Gravel is a quick and economical way of transforming an unused part of the garden into a space you want to spend time in.

Pea gravel, slate chippings, and pebbles are significantly cheaper than most other patio or decking options.

Plus, a gravel patio is comparably quick and easy to install. The DIY-ers amongst us (even some of those firmly in the " Don't DIY " camp) would consider building a gravel patio themselves.

But choosing the right outdoor furniture for a gravelled patio area is crucial for turning your new favourite spot in the garden into a relaxing oasis. Because if you’re not careful, you could end up with a wonky table, chairs that are difficult to move, and expensive garden furniture that soon scratches and chips.

I may be biased, but on gravel, I recommend embracing the Mediterranean outdoor aesthetic by opting for a lounging area rather than a formal dining table and chairs. Think garden bean bags and comfortable modular sofas, with weatherproof ottomans for sharing plates.

Here’s our top tips for building a gravelled seating area that works.

Is gravel good for a seating area?

Yes, if you choose the right type of furniture for it. The best furniture for gravel features broad bases or sled legs to prevent sinking, and rust/rot-resistant materials that don’t scratch or tear easily. 

Gravel is fuss-free, low-maintenance, and a quick, achievable solution for creating the perfect spot in the garden to relax.

7 tips for a gravel patio that outdoor furniture won't sink into

1. Choose the best gravel for a seating area

The experts at Stone Warehouse also recommend opting for angular chippings over rounded pebbles. Angular chippings bed together and lie flatter, forming a smoother surface for furniture.

I'd advise choosing stones that are not too small but - to channel Goldilocks - not too big either.

Between 12mm and 20mm works well. Smaller stones will shift and slide under furniture, leaving garden guests feeling sea-sick every time they sit down! And larger stones can be uncomfortable underfoot.

There is a wealth of size and colour options for a gravel patio from pea shingle to decorative slate chippings. Much comes down to your personal preferences and outdoor aesthetic.

2. Lay a patio sub-base

It adds heaps more stability for garden furniture. The recommendation is a MOT Type 1 aggregate laid to a depth of 10cm. This will promote easy drainage but compact to an even surface.

Make sure to put weed membrane fabric down on top of the sub-base and under the decorative gravel top layer - it stops them from mixing.

3. Put weed membrane under the gravel patio

If you decide not to use a patio sub-base, at the very least, put down landscape fabric. 

It will prevent patio furniture from pushing the stones into the underlying soil, as well as reduce the time future-you spends weeding!

4. Think carefully about the depth of gravel on your patio

The rough rule is to fill your patio area to a depth of at least twice the gravel size to minimise bare patches, i.e., if you're using 20mm gravel, fill to a depth of 40mm.

For a seating area, don't be tempted to overfill. Especially if you’re choosing furniture with legs, you’ll feel like you're shoving the chair legs through sand every time you move them. Plus, the legs of your furniture will sink deeper and more unevenly. 

If you want to avoid sinking in completely, opt for furniture with a flat base. Take a look at our bean bag sofa sets. The wide, flat base made from durable fabric works well on all gravel patios. 

5. Consider using a honeycomb stabilisation grid

For extra stability and a firm base for outdoor tables and chairs, use a gravel grid. The honeycomb-shaped base layer will hold the gravel in place and bind it into a firm, flat surface. 

With a gravel grid stopping stones from migrating, there is less temptation to overfill your patio and risk the feeling of sitting on sand. You need just enough gravel to fill the pockets in the grid, plus a shallow topdressing so you don't see it.

Putting down a grid to secure the stones will also make your gravel patio more accessible to wheelchair users. 

6. Use slabs under heavy furniture

To give garden furniture a solid, even base, you could use cheap patio slabs under the furniture and push the gravel around and over them. This works well for a table, bench, or fixed garden sofa. It's less of a convenient solution for chairs that need to move over the ground.

7. Choose the right furniture for a gravel patio

Gravel is often used for an 'off-patio' seating area - perhaps a bench in a cosy corner or a fire pit area with fixed bespoke seating.

However, if you do want a table and chairs on your gravel patio, bear in mind that gravel shifts and moves under narrow table legs - even when all of the above is considered. 

It will also chip and damage metal or rattan, increasing the risk of rot or rust. Look for furniture with plastic screw-in feet for added protection.

What is the best outdoor furniture for a gravel patio?

Look for lightweight patio furniture that’s broad-based, tough and easy to clean. Here’s a handy guide to help you choose the right furniture for your seating area. 

  • Using lightweight furniture, like garden bean bags, as opposed to heavy furniture, which compresses the stones into the ground, quickly making it uneven.

  • In dry weather, dust from the stones of a gravel patio can accumulate on garden furniture, and in wetter weather, especially without an underlying weed membrane, mud will come up from the ground and stain sofas and chairs, so choose patio furniture that can be jet-washed to minimise maintenance time and maximise time spent enjoying your patio! 

The most important feature of your gravel patio furniture is that it is wonderfully comfy! A gravel patio adorned with bright, patterned fabrics and plush, inviting seating is the perfect place to relax and host friends.
