Trundle beds slide under the main bed for storage and pop out when guests visit. The mattress needs to be thin (under 8″) to fit under the main bed, firm enough to use occasionally, and easy to move. Here are our top picks.
| Pick | Thickness | Best For |
| Zinus Green Tea 6″ | 6″ | Most trundles |
| Linenspa 8″ Hybrid | 8″ | Larger trundles |
| Allswell Original Slim | 8″ | Budget pick |
| Tuft & Needle Mint | 10″ | High-clearance trundles |
| Tempur-Adapt Slim | 8″ | Premium foam |
1. Zinus Green Tea 6″
The thinnest option — fits virtually every trundle frame. Adequate comfort for guest use.
2. Linenspa 8″ Hybrid
Pocket coils at 8″ thickness — better support for adult guests.
3. Allswell Original Slim
Slightly more premium than Linenspa, similar dimensions.
4. Tuft & Needle Mint
For oversized trundles with extra clearance. Premium foam comfort for guests.
5. Tempur-Adapt Slim
Premium memory foam in a thinner profile — overkill but indulgent for guests.
Measure your trundle frame
Most trundles accept 6-8″ mattresses. Some support up to 10″. Measure clearance before buying.
