Thule Sleek

see 7 parent reviews

The Thule Sleek was released in June 2018 and awarded the prestigious Reddot Design Award in the same year. This modern, highly versatile stroller (or a stroller system) is suitable for one single child as well as convertible into a double - tandem mode, when a sibling arrives, or if you are expecting twins. By adding the optional glider board, the Sleek can handle up to three children. To achieve the lightest weight, maximum durability, and a higher weight capacity, the chassis is made of aluminum. It also features soft suspension for a smoother ride. The smaller front wheels are foam-filled, while the rear wheels are more substantial and feature foam-filled tires. The Sleek allows you to fold the chassis even with the seat still attached, but it is not the most compact fold.

The Sleek is usually available as a stroller only, with one or two carrycots, the second, slightly smaller seat, and/or car seat adapters for various car seat brands sold separately. It comes with a soft seat liner and an adapter kit included; all other accessories are available optionally. The bucket-type seat unit can be easily tilted into three positions. The leg rest is adjustable too. Thanks to the soft padding and the ventilation in the hood and the back of the base, the spacious carrycot offers comfortable space for the baby. Using the included tandem adapters, the chassis is compatible with two seat units (in any direction), a combination of a seat unit with a carrycot or a car seat, two carrycots, or two car seats. The Sleek offers 14 various combinations, so you can choose exactly what you need.

Parent reviews of the Thule Sleek

if you own(ed) it, own it ;-)
parents say thx^^

If you don't live in a city, don't buy this

1
  • Good push
  • Sturdy (if you see this as a pro, like my husband did, in the store. His perception changed once he started to haul it to our appartment and in the trunk of the car...)
  • Clunky
  • Not folding with the seat
  • Heavy
  • Wobbly baby bassinet
  • Buttons are so damn hard to push (this might be a Thule "feature" as we own a bike trailer from and the buttons on that are just as hard to push)

Don't buy this, especially if you live in a city. Honestly even if you don't live in a city, don't buy this. It's super clunky, it's super heavy, my husband describes it as a tank. That sums it up pretty well. It's a nice push but that's about it. Unfortunately, it's also entirely unsuitable beyond 16 months. My son, who is maybe on the taller side, just didn't fit in it at all anymore at 16 months. It's really not worth the money.

Poor design

2
  • The sibling seat is too small for second child and only fits in the bottom forward-facing position where you would typically want the larger child
  • The sibling seat is small – seat depth only appropriate for smaller child so with twins both seats would need to be same size
  • Very disappointed in the way the design is presented and advertised. Paid a lot of money for something that is not functional for twins. Called customer support, and they agreed with me (not a good sign)

Purchased used for twins, but not appropriate… poor design.

A larger toddler won't fit in the seat anymore, and it's hard to put him in the lower seat. Otherwise, it feels good in my hand - it is simply just better for twins than for a baby and a toddler.

  • good-looking
  • quality
  • sibling-ready
  • foldable bassinet
  • bulky
  • not many nice colors to choose from
  • dark bassinet

It is very nice-looking, and with quite a spacious main seat. We only use it as a single at the moment - and bought it hoping to have a second in the near future. It is not the smallest folded size but it's understandable. I only wish they'd make it in colors as well.

  • solid frame
  • basket is zip-close
  • steering
  • well-made materials
  • unique look
  • nice suspension
  • rain cover included
  • seat is shallow
  • seat wobbles on the frame
  • takes up a lot of room therefore not easy to store in a small flat
  • difficult to carry - on the heavy side and without a carry handle
  • not a smooth fold
  • not easy to get hold of the recline mechanism
  • I'd welcome more recline positions
  • harness buckle

They call it a city stroller, and yes, it's mostly that. I very much like it on paper, but some features could be maybe better thought-of, they may be frustrating. The versatility of the single as well as double use is great - you have various options. AND it folds with the seat attached, which is not always the case. The bulky fold and the not-always-smooth mechanisms nag me quite a bit, however.

A premium stroller

4
  • quality fabrics & finishes
  • solid chassis
  • on the larger side

A premium stroller: quality fabrics, finishes, and a solid chassis that works well. The carrycot is deep and comfortable. Recommended.

We were deciding between the Sleek and the Vista. We went for the Sleek and I am not sure we did so well. It's difficult to put apart (removing the rear wheels and the carrycot). The frame squeaks a bit. When on terrain or snow, the front wheels get full and you push the stroller by force. I expected a bit more.
