Why We Love this Outdoor Chaise Lounge

I had originally built this project for a rental property, but it turned out so well, we just had to keep it for ourselves.  It's such a versatile piece.  Here's why we love it:

  • NO moving parts, so it's less things to break and maintain.  Instead of a reclining back, the base is long enough to be a bed on it's own.  Simply arrange pillows for the perfect back support.
  • Versatile - can work as an outdoor sofa or sectional too!
  • Easy to build
  • Simple style works with most other pieces
  • Can be stained or painted a variety of colors

How Much Did it Cost To Build?

The wood frame cost about $75 to build, the cushion cost about $50, and then add in all the pillows, stain etc, I estimate $150-$200 per chaise lounge.

We also ended up LOVING these chaise lounges so much, we spent another $50 on waterproof covers to cover them when not in use.

What Did You Use for a Cushion?

For the cushion I used a foam cot mattress measuring 30" x 75" - I bought mine at Fred Meyer (a Kroger Chain store similar to Walmart).

The foam should drain water through.  You can drill small holes in the foam to allow water drainage if the foam cells do not allow water drainage.  There are lots of options on Amazon to buy a "foam cot sized mattress".  

I then added a layer of outdoor batting to the top, so the mattress didn't seem so square and added some softness, and sewed a cushion cover.  Here is a good tutorial for sewing a box cushion cover (I am not an expert a sewing, so will defer you to someone who is).

Other Options for Cushions

This plan is easily adaptable to work with different sized cushions.  Here's a few options to consider:

  • Twin Mattress - foam, waterproof or use a waterproof cover.  Can use a twin daybed cover or twin fitted sheet - spray with waterproofing fabric spray to protect it (Scotchguard).  
  • Three Deep Seat Cushions - Deep seat cushions are a great choice and will already come covered.  Some may even come with pillows.  Measure the size of the cushions and adjust the cuts accordingly.
  • Chaise Lounge Cushion - yep, you can use this.  But do consider since there is no reclining back, there may be an oddly placed break in the cushion.  

What Type of Wood To Use for Outdoor Furniture?

The best option for wood is hem fir 2x4 material (the red toned 2x4s).  I even prefer fir to cedar, since it is a more dense wood and I see it holding up better over time when finished appropriately.

For the slats, cedar is preferred - yes, you can use fence pickets but do sand well.

You can also use fir or pine, but do keep up with finishing the wood, re-coating as directed on the stain can.


What Type of Finish Should I Use for Outdoor Furniture?

Choose an exterior stain used for decks, siding and fences.  For a "paint" look, use an opaque stain in your desired color.  Avoid film forming paints or clear poly coats that may crack and peel when the wood expands and contracts with moisture.  

Exterior stains are also easy to recoat to keep your projects looking beautiful and protected for years to come.


Consider Ordering Covers

I loved this project so much, I ordered covers on Amazon for $25 each.  The covers will protect the cushions and pillows too.
