What the CPSC Data Shows

Hammocks (CPSC product code 5037, in the Swimming, Water & Beach Equipment category) generate an estimated 4,329 emergency-room visits every year in the United States, adding up to roughly 86,570 ER-treated injuries across the 20-year span from 2005 to 2024. PlainSafety derives a danger score of 37/100 for this category (low risk), combining raw injury volume, demographic reach, severity of outcome, and multi-year trend. The five-year trajectory shows that injury counts are rising by about 19% over the last five years, with the busiest year on record being 2022 (6,556 estimated ER visits) and the quietest 2006 (2,401 estimated visits).

The single most common ER diagnosis for hammocks is internal injury to the head, accounting for approximately 15,383 visits across the 20-year NEISS window, followed by laceration to the head (6,418 cases). The 5-14 age group absorbs the largest share of injuries, about 35,357 cases over the NEISS window, and females appear slightly more often than the opposite sex in that cohort. Severity outcomes from the NEISS disposition field show that 3.6% of ER visits involving this product end in hospital admission or transfer.

Beyond the hospital-sampled NEISS projections, this page also aggregates 26 consumer incident reports filed directly on SaferProducts.gov, plus 20 anonymized ER narratives - together forming a layered picture of how hammocks fail in real households. Every figure on this page comes from CPSC-published data: NEISS projects national estimates from a probability sample of about 100 U.S. hospital emergency departments, while SaferProducts.gov collects voluntary reports from consumers, manufacturers, and clinicians. The danger score, trend indicators, and demographic breakdowns update automatically when CPSC releases a new yearly NEISS file, which is why this page is dated 2024-12-31.

9/27/2014 · Injury, No First Aid or Medical Attention Received · Vivere Ltd. · Georgia

I bought a Vivere 2 person hammock. When the hammock was hooked up and sat in, the ropes on one side snapped and the person fell to the ground hitting her head. The ropes were tied together in a knot and the hammock was tried again. the other side of the hammock ropes started to crackle and also ripped apart, making the person fall to the ground a second time, this time hitting their legs and rear end on the ground.

9/26/2015 · Injury, Seen by Medical Professional · Bed Bath & Beyond Inc. · Michigan

I laid on the hammock and when I tried to move up alittle the hook popped out and I fell first hitting my head very bad on the pole thats angled and landing on the pole that is on the ground which resulted in me not being able to walk the next morning without having back spasms. I produced a bruise from the top of my tailbone that became extremely wide also over my buttock. I had to go to urgent care and got x-rayed for my tailbone and was given a shot to help with the spasms.

9/1/2017 · Incident, No Injury · Binxy Baby, LLC · Massachusetts

I was given a binxy baby shopping cart hammock as a baby gift. Today, I was in target using it with my baby (born 5-9-17). The hammock was installed on the cart as instructed and she was bucked in. After some time, she wriggled out in a way that made her head come over one side of the hammock and become stuck between the hammock and the far end of the cart. Not only was her head stick such that she couldn't free it, her head and neck were in a very unnatural pisition. I had only looked away for seconds and I freed her immediately. She seems fine. I think the hammock is problematic, particularly when the cart it is used on has sides that are not nearly parallel. The baby leans to one side and their head can too easily come off the hammock and hang down and even become stuck, as my daughter' did.

8/9/2016 · Injury, No First Aid or Medical Attention Received · Bring Your Adventure Sports · California

We set up the hammock as directed in the instructions and the ring/tie mechanism failed when someone who was laying in the hammock tried to get out of the hammock. The weight limit is for 400 lbs, and the individual is well-under the weight limit at 280 lbs. They attempted to get out, but the ring/tie mechanism failed at the same time and he fell to the ground. With only slight bruising on his bottom, he was fine, but the recall on this item states that it is only for items sold just 2 months earlier, and I believe this product also belongs in this category.

8/30/2018 · Injury, Emergency Department Treatment Received · costway · Alabama

the item was purchased online at walmart.com. The supplier is costway. The pod hammock swing broke with my 8 yr old son in the seat. He fell from the swing, it ripped at the top, and as a result received a concussion. He was transported to the ER by ambulance. He had difficulity walking and talking. He was in great pain. The product is aimed at children. The swing did not break at any seam, it ripped below the ring that hooks to the c stand. This product is extremely unsafe. I asked the company to add a warning label so other children wont get harmed, but they refused to communicate with me. My son should never never been in that swing, because it is dangerous. I read online that many of their items are not properly made. Someone please help, so no other child gets hurt. My son is autistic and this swing is aimed at children with special needs. This is dangerous.

8/26/2011 · Injury, First Aid Received by Non-Medical Professional · L G Sourcing, Inc. · Georgia

I have Garden Treasures Hammock (Item #: 206254 | Model #:SC-XHMK-NN) bought at Lowes in April 2010. On August 20, 2011 the stitching in the end seam of hammock bed came apart with my 7 year old son (weighs about 60 lbs) sitting on it and he fell. He was just sitting, not bouncing or jumping. It appears that the stitching is made from a thin cotton, non-durable tread. The tread was certainly not suitable for an outdoor product. It creates a very foreseeable safety/falling hazard. While my son only sustained minor bumps and bruises it could have been much worse had an adult been laying prone on the hammock. Customer reviews on Lowes website indicate this is a common problem. Your assistance in getting this hazardous product off the market is needed. Thank you [REDACTED]
