Quick Answer: SereneLife sells four current mini trampolines: the 48-inch Pro Aerobics with a built-in handrail (264 lb capacity, about $107.99), a 40-inch adjustable-handrail model (220 lb, $104.99-$169.99), a 36-inch foldable mini with no handrail (around $59.99-$95.99), and a 36-inch kids’ model (150 lb, about $72.99). The 48-inch Pro Aerobics is the best overall pick for most adults on capacity and price. The one thing to verify before buying: the 36-inch foldable mini’s own retailer listings disagree on weight rating by 110 lb — one lists 330 lb, another lists 220 lb for the identical model — so don’t assume the higher number without checking the listing you’re actually buying from.
SereneLife already gets passing mentions on this site — the 48-inch handrail model shows up in our best trampoline for seniors guide and our best trampoline handlebar guide as the built-in-rail alternative to JumpSport — but the brand has never had its own dedicated roundup here. SereneLife actually sells four different rebounders, not one, and sizing them up side by side surfaced a real spec conflict worth flagging before anyone buys based on a single retailer listing.
By the numbers
- 264 lb vs. 220 lb — the single-jumper weight rating on SereneLife’s 48-inch Pro Aerobics versus its 40-inch adjustable-handrail model, per Walmart’s and Target’s own listings — the larger rebounder carries the higher capacity, not just a bigger jump surface.
- 330 lb vs. 220 lb — the two conflicting weight ratings found for the identical 36-inch foldable mini (model SLSPT365) across different retailer listings, a 50% spread on the same product.
- 43-51 in — the adjustable handrail height range SereneLife publishes for both its handrail-equipped models, sized to fit most adult users without a separate accessory purchase.
- 0 — the number of CPSC recalls on record for any SereneLife trampoline or rebounder, as of this writing (CPSC.gov search, direct).

1. SereneLife Pro Aerobics (SLELT518) — Best Overall
SereneLife Pro Aerobics Fitness Trampoline, 48 Inch
- The largest jump surface and the highest weight rating in SereneLife's current lineup, at 264 lb — ahead of the 40-inch model's 220 lb rating.
- Built-in adjustable handrail, roughly 43-51 inches, so there's no separate accessory to buy or fit.
- Galvanized steel frame, listed for indoor or outdoor use, folding for storage between sessions.
- Already this site's reference pick for a built-in-rail alternative in our best trampoline for seniors guide.
Ordering the rebounder and a floor mat to go underneath it at the same time? Try Amazon Prime free for 30 days so both arrive together instead of the mat trickling in days later while the rebounder sits unused on bare flooring.
The size-to-capacity jump here is real, not just marketing — a bigger mat with a genuinely higher weight rating, for a modest price step over the 40-inch model. For most adults without a strict space constraint, this is the one to buy.
2. SereneLife 40-Inch Adjustable Handrail — Best for Smaller Spaces
SereneLife 40-Inch Portable Fitness Trampoline with Adjustable Handrail
- Same built-in adjustable handrail design as the Pro Aerobics, in a smaller 40-inch frame that fits tighter rooms.
- 220 lb capacity — 44 lb lower than the 48-inch Pro Aerobics, the direct tradeoff for the smaller footprint.
- Includes a padded cushion and travel bag on current listings, a bundle the larger model doesn't include.
- Pricing swings widely by retailer and sale timing — we found listings from $104.99 (sale) up to $169.99 (list) for the same model.
Worth it specifically if the Pro Aerobics’ 48-inch footprint doesn’t fit the room — otherwise the larger model’s higher capacity at a similar real-world price makes it the better default.
3. SereneLife 36-Inch Foldable Mini (SLSPT365) — Best Budget / Storage
SereneLife 36-Inch Foldable Mini Rebounder
- The smallest and least expensive model in the lineup, and the only one designed to fold flat for storage under a bed or in a closet.
- No built-in handrail — pair it with an add-on bar from our best trampoline handlebar guide if balance support matters.
- Important: retailer listings disagree on this model's weight rating — one lists 330 lb, another lists 220 lb for the same SLSPT365 model number. Shop against the lower figure and leave real margin rather than assuming the higher one applies to your specific listing.
- Exposed metal joints at the frame hinges have drawn safety comments in buyer reviews — padding them before use is a reasonable precaution on this specific model.
The cheapest way into rebounding, but the one model here where it’s worth reading the specific listing’s weight rating carefully rather than trusting a single number across retailers.
4. SereneLife 36-Inch Kids’ Model — Best for Kids
SereneLife 36-Inch Kids' Trampoline with Padded Frame Cover
- Rated to 150 lb, the lowest capacity in the lineup, scoped specifically for kids rather than adult rebounding.
- Padded frame cover over the springs, a safety feature the adult-focused models in this lineup skip.
- If a full-size backyard trampoline is the actual goal rather than an indoor rebounder, see our best toddler trampoline guide instead — this model is an indoor fitness-style mini, not a yard trampoline.
The right pick only if a kid-scaled indoor mini is actually what’s needed — most households shopping for a backyard trampoline for a child want a full-size model instead.
The one spec worth double-checking
SereneLife’s lineup is otherwise straightforward — capacity tracks size, and the two larger models both include the handrail the smaller two skip. The exception is the 36-inch foldable mini: its own retailer listings can’t agree on the weight rating, with one source putting it at 330 lb and another at 220 lb for the same SLSPT365 model. That’s not a rounding difference or a sale-price-style discrepancy — it’s a 50% gap on a safety-relevant number. Until SereneLife’s own spec sheet resolves it consistently across every listing, the safer approach is to shop against the lower figure and add real margin under it, the same conservative-rating guidance this site already applies to the handlebar-equipped rebounders in our best trampoline for seniors guide.
The bottom line
SereneLife’s four current rebounders run from a $59.99-$95.99 36-inch foldable mini up to a $107.99 48-inch Pro Aerobics, with the two larger models adding a built-in adjustable handrail the smaller two don’t have. The 48-inch Pro Aerobics is the best overall buy for most adults — the highest capacity in the lineup at a price close to the smaller handrail model’s own sale pricing. Buy the 40-inch model only if space is genuinely tight, and if the 36-inch foldable mini is the one you’re considering, check your specific listing’s weight rating before assuming the higher of the two conflicting numbers applies. No CPSC recall exists for any SereneLife trampoline as of this writing; the one SereneLife recall on record is for an unrelated above-ground pool product.
