Our Guide to the Best Cold Frames Under $150
Five cold frames under $150 compared on raised-bed design, shelves, panels and venting, from the Outsunny bed to shelved fir cabinets.

11 min read5 products evaluated
Once you pass $100 the cold frame stops being a box with a lid and becomes furniture. You get raised beds, removable shelves, sloped roofs and real polycarbonate. That is good for results and for looks, and it brings new decisions.
The biggest is whether you want soil or shelves. The Outsunny sits over a 12 inch deep raised planter you fill with soil. The GRAFFY, DREAMADE and MCombo are shelved cabinets for pots and trays, and the Adigyco is a bare polycarbonate frame.
For regular use over several seasons, venting and drainage are what matter. A roof that sheds rain and lifts to at least two heights keeps plants dry and cool, and a base that lets water out keeps the wood from rotting.

Why Each Pick Made the Cut
Best Raised Bed1 of 5
Outsunny Raised Bed Cold Frame on Amazon (opens in a new tab)
The only one that is also a planter: a 12 inch raised bed with a twin-wall polycarbonate cold frame on top.
Best for
- growing in soil year round
Our take
A galvanized steel raised bed 35.5 inches wide, 31.5 deep and 12 inches high, with a 32.5 by 28.5 inch planting area, topped by a peaked twin-wall polycarbonate greenhouse in a stained fir frame. The roof opens for ventilation and the greenhouse can be used alone.
Where the other picks need pots or trays, this one lets roots go into soil, so lettuce, spinach and kale can grow for months. It also costs the most here and weighs more, so it is not a cabinet you move around.
Choose it for cut-and-come-again greens through winter. Skip it if you only grow pots, where the GRAFFY gives more tray space.
Key dimensions & specs
- 35.5 x 31.5 x 36 in
- 12 in deep steel bed
- Twin-wall polycarbonate
Pros
- 12 inch deep bed lets roots go into soil
- Twin-wall polycarbonate roof holds heat through cold nights
- Peak roof opens for venting and access
- Galvanized steel bed will not rot
Cons
- Costs the most and is heavy to move
- 32 inch planting area suits only a few plants
Best Shelved Frame2 of 5
GRAFFY 3-Shelf Wooden Cold Frame on Amazon (opens in a new tab)
Three removable shelves and a sloped, shedding roof make it the tidy choice for trays and potted starts.
Best for
- trays and pots on shelves
Our take
A natural fir frame with three removable shelves, a transparent flip-top roof and a sloped design that drains rain quickly. At about 20 lb it can still be moved between spots, and it is 58 inches tall.
Compared with the DREAMADE it has a flip roof rather than two doors, which makes airing the whole frame at once simpler. It is bigger than the Adigyco and holds far more trays, but it does not offer a soil bed like the Outsunny.
Pick it for seed trays and hardening off. Skip it if you want to grow directly in the ground.
Key dimensions & specs
- 3 removable shelves
- Fir wood, 20 lb
- Sloped flip-top roof
Pros
- Three removable shelves hold many trays
- Sloped roof drains rain without pooling
- Weighs about 20 lb, still movable
- Flip-top roof airs all shelves together
Cons
- Untreated fir needs sealing against rot
- 58 inch height catches wind on open sites
Best Two-Door Cabinet3 of 5
DREAMADE 3-Tier Wooden Greenhouse on Amazon (opens in a new tab)
Two flip-top doors let you vent the top shelf without exposing seedlings below it.
Best for
- ventilating one shelf at a time
Our take
A natural fir three-tier cabinet, 52.5 inches tall, with removable shelves, transparent polycarbonate panels and two flip-top doors with side support rods. It weighs about 20 lb and the surface is polished for staining or painting.
The two doors give better control than the GRAFFY's single roof: you can open one side on a mild day and keep delicate plants sealed. It has the same shelf count and weight as the GRAFFY.
Choose it when you grow plants with different temperature needs on separate shelves. Skip it if you want a simpler single-lid design.
Key dimensions & specs
- 3 removable shelves
- Two flip-top doors
- Fir wood, 20 lb
Pros
- Two flip-top doors vent shelves separately
- Polycarbonate panels let light in evenly
- Support rods hold doors open at angles
- Polished fir can be stained or painted
Cons
- Two doors mean more hinges to maintain
- No steel or metal parts to resist rot
Best Adjustable Shelf4 of 5
MCombo Wooden Cold Frame Greenhouse on Amazon (opens in a new tab)
One shelf with four preset heights, roof grooves for drainage and four metal brackets for stability.
Best for
- mixing tall and short pots
Our take
A pure fir cold frame with one shelf that moves through four preset heights, a roof held open by a side bolt and screws set at different positions to adjust the vent gap. Grooves in the roof stop rain pooling, and four metal brackets add stability.
It is the lowest-profile of the cabinets at about 27.6 inches tall, so it suits low pots rather than the GRAFFY's tall trays. The adjustable vent gap offers more control than a plain flip lid.
Pick it for a few tall pots on one shelf and low ones below. Skip it for lots of trays, where the GRAFFY holds more.
Key dimensions & specs
- 4 preset shelf heights
- Pure fir wood
- Roof groove drains water
Pros
- Shelf adjusts through four preset heights
- Vent gap set by moving screws
- Roof grooves shed rainwater instead of letting it pool
- Four metal brackets steady the frame
Cons
- Only one shelf, so tray capacity is limited
- Low 27 inch height limits tall seedlings and starts
Best Rigid Panels5 of 5
Adigyco Polycarbonate Cold Frame on Amazon (opens in a new tab)
A rot-free aluminum frame with polycarbonate panels, the lowest-maintenance cold frame in this group.
Best for
- a durable, low-maintenance frame
Our take
A 38.5 by 22.4 by 24 inch frame in aluminum with polycarbonate panels and an openable roof. It weighs about 6.6 lb, so it is the lightest choice and easy to carry.
Unlike the fir cabinets it has no wood to seal and no rot. It also has no shelves and the smallest growing area, so it is for a few trays rather than a whole collection.
Choose it if you want a frame you can leave outside for years. Skip it if you need shelves or a soil bed.
Key dimensions & specs
- 38.5 x 22.4 x 24 in
- Aluminum frame
- Polycarbonate roof opens
Pros
- Aluminum frame never rots or needs sealing
- Rigid polycarbonate panels hold overnight heat
- Weighs about 6.6 lb for easy carrying
- Roof opens for watering and ventilation
Cons
- Small footprint, no shelves for trays
- Light weight means it needs anchoring
How We Built This Shortlist
Each pick was assessed across 5 criteria weighted for real-world use.
- Soil or shelf design
- Each frame was sorted by whether it grows in soil or holds pots, since that decides what a gardener can do with it.
- Roof and venting
- Lid shape, support rods and vent adjustment were compared for how well each handles heat and rain.
- Panel and frame material
- Twin-wall, fluted and clear panels and fir, steel or aluminum frames were compared for insulation and durability.
- Stability and weight
- Weights, brackets and heights were compared to see which frames resist wind and which need anchoring.
- Value in the $100 to $150 band
- Extras such as shelves, brackets and raised beds were weighed against cost.
What Matters Before You Choose a Cold Frame
Key buying criteria so you get the right fit the first time.
Soil bed versus shelves
A cold frame with a soil bed grows roots, while a shelved frame only protects pots and trays. Greens grown in soil under cover can last through winter, but pots stop growing when roots freeze. Decide whether you plant or pot before comparing the rest.
Roof angle and drainage
A sloped or peaked roof sheds rain, and one that pools water rots the wood and drips onto seedlings. Roof grooves, as on the MCombo, add drainage. Check that the lid sits on a slope and is not flat.
Vent gap adjustment
A lid that opens fully is not enough, because many days need a two-inch gap, not a wide open frame. Look for support rods, bolts or screw holes that hold the lid at more than one angle. A stiff single prop leaves you with one setting.
Panel type and clarity
Twin-wall polycarbonate insulates better than a single-skin or fluted panel, while a clear panel passes the most light. For winter greens, pick twin-wall. For seed starting under mild sun, a clear or fluted panel works.
Fir wood care
Untreated fir greys and rots if it stays wet, so exterior stain or sealant extends its life. Look for a polished or smooth surface, which takes finish better. Metal brackets help stop joints loosening.
Frame weight and wind
A 20 lb cabinet tips less easily than a 6 lb frame, yet either will blow over on an exposed site. Keep tall frames against a wall or fence, and weigh the base with bricks. Heavier frames are harder to move between beds.

Shelved Cabinet vs Raised Bed Frame
- Shelved cabinets
- Hold trays and pots on shelves with a lid or doors, and they are easy to move. Best for seed starting and hardening off. In this comparison: GRAFFY 3-Shelf Wooden Cold Frame, DREAMADE 3-Tier Wooden Greenhouse and MCombo Wooden Cold Frame Greenhouse.
- Raised bed frames
- Sit over soil and let roots grow, which keeps greens producing in winter. Best for in-ground growing. In this comparison: Outsunny Raised Bed Cold Frame and Adigyco Polycarbonate Cold Frame.
Most gardeners who want winter harvests should choose the raised bed, and others the cabinet.
By Wind and Site
| Site | Recommended pick | Why |
|---|---|---|
| Sheltered patio | GRAFFY 3-Shelf Wooden Cold Frame | 58 inch frame stays upright against a wall |
| Exposed corner | Outsunny Raised Bed Cold Frame | Steel bed adds weight and stability |
| Balcony railing | MCombo Wooden Cold Frame Greenhouse | Low 27 inch height and metal brackets |
| Mixed sun and shade | DREAMADE 3-Tier Wooden Greenhouse | Two doors adjust per shelf |
| Anywhere, light frame | Adigyco Polycarbonate Cold Frame | Light enough to move, anchor it down |

For Winter Greens Specifically
- Look for
- A soil bed deep enough for roots, twin-wall panels for insulation and a vent gap you can set for cold sunny days.
- In this comparison
- The Outsunny Raised Bed Cold Frame has a 12 inch bed and twin-wall roof, while the Adigyco Polycarbonate Cold Frame adds a rigid cover over a bed you already have.
When to Spend More
- Spend more if
- You want a bigger raised bed or a greenhouse cabinet in aluminum. The Outsunny Raised Bed Cold Frame is the top pick at this tier, and mini greenhouses above $150 add height.
- Save if
- You only start a few trays. The Adigyco Polycarbonate Cold Frame is the simplest frame and lasts.
Before You Bring One Home
Can I grow vegetables in a cold frame over winter?
Yes, cold-hardy greens such as spinach, kale and lettuce do well under twin-wall panels in a raised bed. Water sparingly and vent on sunny days.
Do I need a bed under a cold frame?
A cold frame sits over soil or a raised bed, so you need one or the other. The Outsunny includes the bed, while the cabinets sit on a patio and hold pots.
How much ventilation does a cold frame need?
Open the lid a couple of inches on sunny days, and wider as it warms. A frame that can overheat on a sunny 60 degree day needs a lid that opens often.
Will fir wood rot in a cold frame?
Untreated fir can rot if kept wet. Stain or seal it, keep the base off wet ground, and choose a sloped roof.
Are polycarbonate panels better than clear plastic?
Twin-wall polycarbonate insulates better overnight and lasts longer. Thin clear plastic passes more light but ages in sun.
How do I harden off seedlings in a cold frame?
Start with the lid closed, then prop it open longer each day for a week. The GRAFFY and DREAMADE let you vent one side while the other stays shut.
