looks like 6 to me; 4 for the base and 2 for the headboard......most wood pallets are 40 x 48
You might think that pallet wood is free BUT it AIN'T .. there are lots of splinters in that rough hewn wood that is used in pallet construction .... and you will spend many HOURS in sanding and use os a wood plane to get that wood in a usable condition... you have a lot of waste in trying to size the pallet lumber to a full size bed ==== it is cheaper to buy good wood and follow some good plans to make a bed that will work for you .... pallet wood will destroy your linens --- there are good free woodworking plans on the inet == look them up .........
