Overall winner for small spaces: ProForm Carbon TLS. It adds 2% more incline and one-touch controls, and its listed folded size is far smaller, which is what counts when the treadmill has to disappear after each walk. The ProForm Carbon TL is the better fit if you will move it often and want the lighter frame.

ProForm Carbon TL vs TLS: The ProForm Carbon TL and Carbon TLS are near twins: both have a 2.6 HP motor, 0–10 mph, an 18 × 55-inch deck with ProShox cushioning, a 5-inch LCD with a device shelf, a 300-lb rating and iFIT support. The TLS climbs to 12% instead of 10%, adds one-touch speed and incline buttons and, per its Amazon listing, folds down to about 34 × 32 × 28 inches; the TL is about 39 lb lighter but its listed folded size is much longer.
The Carbon TL ranks #3 in our best budget treadmill guide and #4 in our best treadmill for small spaces guide. For more detail, read our ProForm Carbon TL review and ProForm Carbon TLS review.
Head-to-Head Specs
Here are the two models side by side, from their Amazon US listings. A check mark shows the stronger spec on each line. Before you order either model, search the CPSC recall database: the U.S. Consumer Product Safety Commission lists treadmill recalls and the fix offered. The American Heart Association recommends at least 150 minutes of moderate or 75 minutes of vigorous aerobic activity a week. If you train for road races, a 1996 study of trained runners found that a 1% incline best matched the energy cost of outdoor running at about 6.5 to 11 mph.

FitScore Duel
Both scores use the weights of our best treadmill for small spaces guide: practicality 50%, comfort 15%, and performance, durability and affordability 10% each, with features at 5%. In a small room, footprint, folding and storage decide whether the treadmill gets used, so practicality counts most. The TLS leads on practicality (72 to 61) thanks to its smaller listed folded size, and edges ahead on performance and durability with its steeper incline; comfort, features and affordability score the same. The TLS is not one of the five treadmills ranked in that guide, so its score uses the same weights.
Key Differences
- The TLS climbs to 12% incline; the TL to 10%. Motor, speed and deck are the same.
- The TLS has one-touch speed and incline buttons; both have a 5-inch LCD and a device shelf.
- Folded, the TLS is listed at about 33.75 × 31.6 × 28.1 inches against about 65.7 × 32.1 × 32.9 inches for the TL.
- The TL is lighter, at about 166 lb against about 205 lb.
- The 300-lb rating, the iFIT features and the listed warranty are the same.
Round 1 of 5
ProForm Carbon TL vs TLS: Motor, Speed and Incline
ProForm Carbon TLS wins this round
Both use a 2.6 HP motor with a 0–10 mph range, which suits walking, incline walking and light jogging rather than regular running. The TLS climbs to 12% incline against 10% on the TL, which matters if hill walking is your main workout.
With an iFIT membership, trainers adjust speed and incline for you on both. Owners of the TL describe it as quiet enough for everyday walking; we found no owner or tester feedback specific to the TLS, so its running feel cannot be compared first-hand.
Round 2 of 5
Running Deck and Cushioning
Tie. Neither model has a clear edge here.
Both list an 18 × 55-inch deck with ProShox cushioning. That length and width suit walkers and light joggers; taller users and runners will find it short and narrow on either model.
Testers of the larger Carbon TLX, which uses the same ProShox name, found the cushioning middle-of-the-road. Expect the same moderate feel here.
Round 3 of 5
Folding and Storage
ProForm Carbon TLS wins this round
This is the real difference for a small room. Both fold, and both listings mention a hydraulic foot bar for a smooth landing. Per the listings, the TL still measures about 65.7 × 32.1 × 32.9 inches folded, while the TLS gives about 33.75 × 31.6 × 28.1 inches, roughly half the length.
Check the listing photos and measure the spot before buying: storage size is the reason to pay for the TLS. The TL’s lighter frame, about 39 lb less, is easier to roll and reposition.
Round 4 of 5
Console, Controls and iFIT
ProForm Carbon TLS wins this round
Both have a 5-inch LCD and a device shelf for a phone or tablet running iFIT. The TLS adds one-touch buttons to jump straight to a speed or incline.
Classes, SmartAdjust and automatic speed and incline control need an iFIT Train membership on both. TL owners report few useful workouts without the app, no pause function and a small unlit display, so plan on iFIT or on keeping things simple.
Round 5 of 5
Assembly, Durability and Warranty
Tie. Neither model has a clear edge here.
TL owners describe a demanding two-person assembly, and some report units failing within a year or two. We found no comparable long-term reports for the TLS yet.
The listed warranty is identical: 10 years on the frame and 1 year on the motor, parts and labor.
Who Should Buy Each
Walkers who must store it after each use
Choose the ProForm Carbon TLS for 12% incline, one-touch controls and the smaller listed folded size.
Walkers who move it around
Choose the ProForm Carbon TL for the same motor and deck in a lighter frame with 10% incline.
Consider Instead
If you jog or run, the ProForm Carbon TLX steps up to a 3 HP motor, 12 mph and a 20 × 60-inch deck; see our ProForm Carbon TL vs TLX comparison. For more compact options, browse our best treadmill for small spaces guide.
Final Verdict
For a small room, the ProForm Carbon TLS is the better buy: the same motor, speed and deck as the TL, plus 12% incline, one-touch controls and a much smaller listed folded size. Choose the ProForm Carbon TL if you will move the treadmill often and the lighter frame matters more than storage size.
ProForm Carbon TLS vs ProForm Carbon TL FAQ
For small spaces, yes: it scores 72.6 against 66.5 with 12% incline, one-touch controls and a smaller listed folded size. The TL is lighter.

An iFIT Train membership is needed for classes, SmartAdjust and automatic speed and incline control on both.
The Carbon TL, at about 166 lb against about 205 lb for the TLS.
Neither. Both are listed at 300 lb.
