Safety guide

Fisher-Price trampoline weight limit guide

Every trampoline in the Fisher-Price range has a maximum user weight that sets a clear boundary between safe use and risk. This guide lists the published weight limits for the four main UK models and explains how to match them to your child, how the limit is tested, and why it matters even more on smaller indoor models.

Published weight limits by model

The weight limits below are taken from the manufacturer's own packaging and instruction booklets for each UK-sold model. Always treat them as a hard ceiling, not an average target, and re-check your own booklet for the batch you own.

Model Age range Max weight
My First Trampoline (1.9 ft) 12–36 months ~25 lb / 11 kg
WonderJump 36-inch Mini 3+ years 55 lb / 25 kg
Junior Trampoline (~4 ft) 3–6 years ~75 lb / 34 kg
4.5 FT Outdoor with net 3–8 years ~100 lb / 45 kg

Manufacturer specifications are updated from time to time. Always defer to the booklet packaged with your own trampoline.

Why weight limits are not just a formality

1. The frame is sized for the load

Each Fisher-Price frame — from the 1.9 ft toddler bouncer to the 4.5 ft garden model — is engineered with a specific dynamic load in mind. A bouncing child puts forces on the frame that can reach two to three times their body weight at the peak of a jump. The stated weight limit builds a safety margin around the expected peak load, not just the child's static weight.

2. Springs and mat wear predictably

Jumpers who are close to or over the limit cause the springs to stretch further and the mat fabric to tension harder each cycle. Over weeks and months this accelerates sag, reduces bounce height, and eventually causes the trampoline to feel "dead" well before its expected lifespan.

3. Handlebars are stability aids, not load-bearing

The handlebars on the indoor toddler and junior models are designed to guide balance, not to take an adult's weight. Testing a toddler trampoline by standing on it yourself "just to check" can bend the uprights and void the warranty.

4. Fall-zones assume a child-size jumper

On the 4.5 ft outdoor model, the net, spring pad and pole padding are specified with children up to around 45 kg in mind. A jumper heavier than that can displace the net fabric or push springs past their intended deflection.

How to check your child's fit

  1. 1
    Weigh your child in light clothing using a household digital scale. Record the number in both kilograms and pounds so you can match whichever the booklet uses.
  2. 2
    Compare to the published limit on the model you own or are considering. Leave at least 10 percent of head-room for growth and for the dynamic peak of jumping forces.
  3. 3
    One jumper at a time. All Fisher-Price children's trampolines are designed for single-user use. Two smaller children together can easily exceed the rated dynamic load.
  4. 4
    Re-assess each birthday. Children grow quickly between ages 2 and 6. A trampoline that suited last summer may have been outgrown by this one.
  5. 5
    Upgrade when outgrown. A child approaching the upper age and weight of a model is ready for the next size up, not "one more summer" on the old one.

What the numbers mean in practice

It is easy to look at a figure like 55 lb or 25 kg on the WonderJump box and assume it is only relevant once your child reaches that weight. In reality, the limit sets the upper boundary for how the mat, springs and frame behave — so the closer a child is to the limit, the more noticeable any small loss of bounce becomes. Children under around 15 kg will get a very consistent, gentle bounce from the WonderJump; children hovering around 22 to 24 kg will still be within spec, but the trampoline will feel firmer and the mat will stretch more on each jump.

The same principle applies across the range. On My First Trampoline, designed for children from 12 to 36 months, the 11 kg limit leaves plenty of headroom for an 18-month-old weighing 10 kg but very little for a sturdy three-year-old. On the 4.5 ft outdoor model, children at the lower end of the 3 to 8 age band typically bounce at around 15–18 kg and barely tension the springs; older seven-year-olds at 35–40 kg will bring the springs closer to their full working range.

Because each trampoline is specified as a single-user product, never think of the limit as a "total" that can be shared between a parent and child or between two siblings. The dynamic forces from two jumpers, even if their combined weight is under the limit, are very different from one jumper and can damage the mat or frame.

Frequently asked questions

Can adults stand on the Fisher-Price 4.5 FT trampoline?

No. The 4.5 ft outdoor model is rated for children and is not a fitness rebounder. Adults should use a dedicated adult-rated trampoline.

Can two toddlers bounce together on My First Trampoline?

No. The frame and mat are designed for a single toddler up to around 11 kg. Taking turns is safer and more fun.

What if my 3-year-old is already near the WonderJump 55 lb limit?

Consider moving up to the Junior Trampoline or 4.5 FT outdoor model, which have higher weight ratings.

Does weight limit include shoes or socks?

The rating is simply the total weight of the jumper. Trampolines should generally be used in non-slip socks or bare feet, never in shoes.
